Extensive urticaria. Urticaria photo symptoms and treatment in adults. Treatment of urticaria in adults, drugs

Urticaria can often be called urticaria, urticaria, or urticarial dermographism. This disease is mainly allergic, and is a rather difficult disease in terms of diagnosis and treatment.

When the first symptoms appear, you should seek help from an allergist-immunologist.. The skin can become covered with a rash such as urticaria for a variety of reasons, so it is necessary to conduct a full examination of the patient and prescribe an individual course of therapy.

The term “urticaria” today unites a large group of diseases that differ from each other in their nature, but have similar clinical symptoms: blisters form on the skin, looking like burn marks from nettles.

Causes of urticaria and its types

Depending on the complexity of the disease, experts distinguish two forms of urticaria: chronic and acute. The main sign of the chronic form is that relapses of the disease can occur either after a couple of months or after several years, often alternating with almost daily rashes and the formation of light gaps. Acute urticaria usually lasts.

Besides, in some cases, doctors diagnose artificial urticaria. This occurs when blister-like stripes of an edematous nature appear on the human body. A similar phenomenon can also be observed in patients suffering from ordinary urticaria.

Some experts also distinguish the so-called atypical form - persistent chronic papular urticaria. However, many doctors dispute the existence of this form due to insufficiently compelling reasons.

There is also a fairly rare disease called mastocytosis. Several of its forms can be called nothing other than urticaria pigmentosa. However, it is completely different from ordinary hives.

Special forms include:

Aquagenic;
Adrenergic;
Cholinergic;
Contact.

Depending on the clinical and pathogenetic features, the following types of this disease are distinguished:

Dermographic;
Vibrating;
Physical;
Cold;
Urticaria, the appearance of which is associated with increased blood pressure.

In fact, urticaria is a classic polyetiological disease. There are quite a large number of reasons for the appearance of the same symptoms.

The most widespread is allergic urticaria, which develops when a person has immediate hypersensitivity to various allergens. This mechanism is the basis of the majority of allergic manifestations. This type of allergy is observed mainly after an insect bite or consumption of any food product.

The immunocomplex type of urticaria develops as a pathological process caused by too active formation of special antigen-antibody complexes. Typically, a rash is a reaction of the body to the administration of serums or medications.

Skin problems are no less common. associated with the manifestation of anaphylactoid reactions. They are characterized by a fairly high ability of mast cells to secrete active proteins, as well as various enzymes. However, there is no effect on the cells of the immune system.

One of the important reasons for the development of urticaria, regardless of its form, is a disruption of normal liver function, which provokes disruptions in the process of destroying histamine, which is a fairly active component of inflammation of allergic etiology. Often the disease is a consequence of autoimmune inflammation, when the immune system mistakes its own body tissues for foreign ones.

Symptoms and manifestations

The main symptom of this disease is the covering of the skin with small blisters - protruding areas of the skin that are very similar to nettle burns or insect bites. Their occurrence is accompanied by quite severe itching. Around the blisters, the surface of the skin becomes reddish. Newly formed elements often grow to relatively large sizes, merging with each other. Such rashes are symmetrical in nature.

Urticaria is characterized by complete reversibility of all skin elements. This means that after the attack of the disease is stopped, the skin will return to its original state, completely cleared of traces of hyperpigmentation and whitish spots. It should be noted that scars do not remain.

Typically, the rash can damage the skin on any part of the body. In addition, they often migrate, appearing on the stomach, on the neck, or in other places. The entire process of urticaria disease is divided into three separate stages:

The beginning of the so-called immunological stage coincides with the moment of direct contact of the human body with any irritant or allergen. Then the pathogen, along with the bloodstream, gradually spreads throughout the body, while the body secretes and accumulates the corresponding antibodies.
During the pathochemical stage, the formation and release of ready-made mediators of the allergic reaction and their contact with the allergen are observed.
The pathophysical stage of the disease is a response of various tissues and internal organs to previously released mediators. It is after an increase in the concentration of mediators in the blood that clinical symptoms of the disease appear.

During the course of the disease, a person experiences itching, which may intensify. Due to the constant desire to scratch areas covered with a rash, small wounds may form on the surface of the skin. What to do if it itches a lot? Everything here is simple and complex at the same time. Try not to scratch.

Be patient. Yes, it’s difficult, but it’s necessary. You can be very careful, but if you scratch the wounds it will only get much worse and can lead to complications, which we talk about at the end of the article.

To distinguish urticaria from rubella, you need to know that the second case is characterized by the following symptoms:

Feeling worse a few days before the rash appears;
Headache;
Decreased appetite;
Malaise;
Runny nose;
The surface of the pharynx takes on a reddish tint;
A couple of days before the rash, body temperature rises to 38.5-39 degrees;
The posterior cervical, occipital and postauricular lymph nodes enlarge, and their pain also increases;
The rashes, oval or round in shape and with a diameter of 2 to 5 mm, are light pink in color;
The rash is small-spotted and does not merge into one spot;
There are no elevations above the skin;
Thickening of the rash is typical for the back, extensor parts and buttocks;
Disappears after 1-3 days.

In some people, rubella is also accompanied by the appearance of asthenovegetative syndrome and quite severe aches in the joints and various muscles.

Often, based on the primary symptoms, urticaria can be confused with a regular allergy. However, with a simple allergic reaction, the rash usually covers the neck, upper and lower extremities, which very rarely occurs with the development of urticaria, which differs in its manifestation mainly on the torso.

Photo of urticaria on the body

Let's see what urticaria looks like in adults in photo pictures:

When to see a doctor? Diagnostics

If the first symptoms of urticaria appear, you should immediately seek help from a specialist such as an allergist-immunologist.

Only he can confirm the diagnosis, because symptoms can be provoked by various factors, and therefore patients with suspected urticaria need to undergo many tests in order to determine the exact cause and prescribe correct and effective treatment therapy.

Standard examination plan:

One of the important components of the treatment course for urticaria is a special lifestyle and mandatory compliance. In addition, it is necessary to take into account that with this disease it is prohibited to take most of the medications that are often prescribed to treat diseases associated with urticaria. Read more about what to do.

Prohibited medications include: codeine, aspirin and any of its derivatives, as well as all kinds of ACE inhibitors. Therefore, it is necessary to warn the attending physician that the patient suffers from urticaria.

As a rule, to treat this disease, an allergist prescribes antihistamines. It is recommended to take the following medications: Zyrtec, Telfast, Erius and other third-generation medications. In some cases, the course of treatment takes at least three months. Don't forget about .

Enema for urticaria

Within three days you need to do a cleansing enema. To do this, you should prepare an Esmarch mug, the position of which will have to be constantly adjusted if necessary. Pure water is poured into it, heated to a temperature of approximately 400C. To achieve maximum emptying, add three teaspoons of rock salt to the water.

If desired, it can be replaced with a few tablespoons of glycerin. Some people use herbal infusions that have an anti-inflammatory effect. The pointed tip of Esmarch's mug is greased with vegetable oil or Vaseline to more gently insert the device into the anus.

Then air is released from the tube, and when liquid flows out of the tip, the tap must be turned off. In this case, it is enough to introduce about two liters of water, holding it in the body for about ten minutes. When repeating the procedure, you should wait about forty minutes so that the rinsing waters of the previous enema completely leave the body.

Does it affect the internal organs of a person - liver, intestines?

The occurrence of urticaria does not in any way affect the condition and functions of various internal organs, because this is a disease of the skin and its causative agent does not affect the tissue of the liver and kidneys, intestinal walls and other organs.

Consequences and complications

Urticaria is characterized by the fact that most people who suffer from it are children and adolescents. The development of the disease in them is caused by the entry of a food allergen into the body. But it is not always possible to determine what exactly is the causative agent of the disease.

The course of the disease should not be left to chance, because neglect of treatment leads to the fact that urticaria turns into an acute form, which worsens from time to time, and relapses can be repeated throughout life. Read about the dangers.

During an exacerbation, patients complain of severe itching, which brings real suffering, as well as scratching the skin until open wounds form on its surface, through which infection can penetrate.

Do they take you into the army if you have hives?

If a young man’s medical history indicates that he suffers from chronic urticaria, the duration of which is more than six months, then he is not subject to conscription into the army. In this case, it does not matter what caused the development of the disease.

Urticaria only seems like a completely harmless disease, but in fact this disease can last a lifetime, bringing many troubles: the body looks ugly due to rashes and scratched wounds, constant unbearable itching, as well as a fairly high risk of contracting other infections.

Hives is a common dermatological disease, its characteristic manifestation is the appearance of blisters on the surface of the skin, which is accompanied by severe itching.

Adults suffer from this disease much harder than children, since there is a certain risk of serious complications. The situation is usually aggravated by failure to seek professional medical help, an incorrect course of treatment, or an incorrect diagnosis.

This article will discuss all the main factors contributing to the appearance of urticaria, as well as its main types, symptoms and methods of treatment.

What is urticaria?

Hives received this name because its external manifestations have a certain resemblance to the reaction that usually occurs when the skin comes into contact with nettles.

Anyone can get it, regardless of age, but in older age the risk of health and life-threatening complications increases. The cause of skin damage during the integument is swelling of the papillary layers of the epidermis, which can occur for a variety of reasons.

Types of urticaria

Depending on the pathogenetic form of the disease, two main groups can be distinguished:

Allergic urticaria. This disease always occurs under the influence of allergens and is of immune origin.
Pseudoallergic urticaria. This form of the disease can occur for a variety of reasons, but allergens do not participate in the provoking processes.

Pseudoallergic urticaria can also be classified into three main forms:

Depending on the clinical picture, three main forms of this disease in adults can also be distinguished:

Acute form, which is characterized not only by damage to the skin, but also by an increase in body temperature and general poor health of the patient.
Chronic form may be observed in the event of the transition of acute urticaria to a recurrent variety. In such a situation, the symptoms of the disease can be observed for several months or even years, after which the urticaria does not manifest itself for some time, but then relapses occur again.
Persistent papular chronic form consists in the constant presence of lesions of the skin, while the disease can progress, capturing more and more new areas of the body. This type of urticaria has many subtypes, the classification is carried out taking into account the reasons that provoked this disease.

Stages

In most cases, the course of the disease can be divided into three main stages, which are described below:

Immunological stage, during which the body comes into contact with the causative allergen or is subject to other irritating effects. In the allergic form, the causative agents of urticaria spread throughout the body along with the blood, which promotes the production and accumulation of antibodies.
Pathochemical stage, on which the first biologically active substances, which are allergy mediators, are usually formed. In case of relapses, ready-made substances are simply produced that begin to interact with allergens.
Pathophysiological stage accompanied by a natural reaction from the internal organs, which is a response to the resulting mediators. An increase in their number and an increase in concentration in the blood causes the main symptoms characteristic of urticaria.

Causes of urticaria in adults

Today, experts believe that the main cause of urticaria in an adult is a genetic predisposition combined with an acute allergic reaction.

However, there are many more factors that can provoke this disease, all of them are listed below:

Symptoms of urticaria in adults

The presence of urticaria can be determined by the following symptoms characteristic of this disease:

The appearance of a feeling of severe itching in certain areas of the body.
Overflow of blood vessels, which is a response to scratching.
The appearance of blisters, the color of which varies from pale pink to red. They may be almost flat or noticeably raised above the skin in the affected areas.
The appearance of grayish or white blisters. Such symptoms develop over time and are a consequence of increasing swelling, while the affected areas retain a red tint along the periphery.
The formation of plaques, which are a consequence of the fusion of round and oval blisters. The outlines can have different shapes, outlines and other features.
Fever, complete loss of appetite, weakness, headache and an increase in body temperature up to 39°C are the main symptoms of acute urticaria.

The blisters that occur with hives and affect the body usually look like this:

The size of the blisters can vary and range from a few millimeters to centimeters.
The color of the blisters is usually pink or red, but in the later stages of the disease it begins to fade.
Hives can affect the entire body or local areas at once.
The lesions can be localized around the genitals, in which case the blisters reach large sizes, but disappear very quickly.

Photo

Below is a photo that clearly demonstrates what urticaria looks like when it affects the human body:

What does hives on the face look like?

Sometimes urticaria affects only the skin of the face or irritation is present on it simultaneously with a rash covering the body.

It looks like this:

Rashes on the face usually appear unexpectedly; no accompanying symptoms or deterioration in well-being are observed.
Externally, the rashes are similar to a typical allergic rash, but they can be confused with acne.
When the lesion is localized in the area around the eyes, fairly large blisters appear, but they quickly decrease in size.

Stories from our readers!
"For a long time I experienced discomfort from dandruff and hair loss. Standard shampoos helped, but the effect was short-term. But this complex was recommended by a friend who used it herself. An excellent product!

The skin stopped itching, the hair combed well and was not so greasy. The loss stopped fairly quickly. I couldn’t even dream of such an effect! I recommend."

What and how to treat urticaria?

Before prescribing treatment consultation with a specialist is required and carrying out primary diagnostics. Usually, making a diagnosis is not particularly difficult, but in some cases, urticaria can be confused with acne, vasculitis, scabies or erythema nodosum. It is for this reason that an examination by a doctor is required to rule out the presence of other diseases.

To avoid confusing urticaria with scabies, you can look here.

Treatment at home

If you seek medical help in a timely manner, treatment is usually carried out without any problems, but in the acute form of the disease it can take up to 6 weeks.

At home therapy usually includes:

Identification of a possible allergen pathogen and eliminating any contact with him. Measures in this case may include more thorough cleaning of the premises, adherence to special dietary requirements, exclusion of contact with pets, or discontinuation of the course of taking certain pharmacological medications.
Systemic therapy, which involves oral administration of drugs, as well as their intravenous or subcutaneous administration.
Local treatment, which is mostly aimed at reducing itching, which minimizes scratching, which complicates the situation.

Diet

When treating urticaria, it is almost always necessary to follow a special diet.

It consists of avoiding the following foods and drinks:

Products containing large amounts of animal fats. In most cases, it is impossible to completely stop their intake into the body, so a maximum reduction in volume is required.
Products containing potentially harmful food additives, hot spices, dyes, flavor stabilizers.
Alcohol products in any form and quantity.

Other important conditions are minimizing contact with various poisons and toxic substances, as well as completely stopping smoking.

Ointments

Local treatment with various ointments can only be prescribed by a specialist: most of these products contain hormonal components, so their independent choice is strictly prohibited.

To eliminate the main symptoms of urticaria, the following drugs are usually prescribed:

"Loriden S" is a common remedy for the treatment of urticaria, its effectiveness is due to the combined effect of the main active ingredients: flumethasone pivalate and clioquinol. They are able to have antifungal and antibacterial effects, as well as relieve existing inflammation. Both substances penetrate quite quickly through the upper layers of the epidermis and quickly eliminate the main manifestations of urticaria. To achieve a positive result, treatment of the affected areas is required 2-3 times a day, the duration of the course should not exceed 2 weeks.
"Gistan N" is an ointment based on glucocorticosteroids of synthetic origin, which in a fairly short time can relieve swelling, stop the spread of an allergic reaction and eliminate existing inflammatory processes. It must be taken into account that this drug has a strong effect on the body, so it is contraindicated for children, pregnant women and nursing mothers, and it is also prohibited for use by patients with syphilis, tuberculosis, any viral infections and fungal infections.
Zinc ointment is considered one of the safest drugs for local treatment of urticaria, so it is often prescribed not only to adult patients, but also to children. This product contains no hormonal components, so it actually does not have any side effects. for urticaria - the ointment will relieve inflammation, dry the affected areas of the skin, and also have an antimicrobial effect.
"Sinaflan" is a fatty ointment that is applied once a day before bedtime. The composition includes hormonal substances, so the drug begins to act quite quickly, but it is prescribed only if it is advisable to use such a potent drug in general therapy.
"Elokom" is an ointment with a rather specific composition, the main active components influence a number of processes and reduce the volume of intracellular acids. Such an effect usually helps to reduce skin intoxication.

Medicines

Any pharmacological drugs for the treatment of urticaria should be prescribed by a specialist, since their choice depends on the form of the disease and the characteristics of its course.

Typically, after diagnosis, the attending physician prescribes the following medications:

Various antihistamines, for example, Loratadine or Chloropyramine. In some cases, more modern drugs are prescribed, which are H1 receptor blockers: Zyrtec or Zodak.
Systemic glucocorticosteroids can be used to treat urticaria, accompanied by multiple skin lesions. The most commonly prescribed drugs are Prednisolone or Dexamethasone.
Sodium thiosulfate is prescribed for intravenous infusions; depending on the characteristics of the disease, from 5 to 10 procedures are required. You can read it in the feature article.
"Hystaglobulin" for subcutaneous administration. A gradual increase in the dosage of the drug is required; the specifics of the course are determined by the attending physician on an individual basis.
Adrenaline hydrochloride solution used for subcutaneous administration if the disease is complicated by laryngeal edema, which leads to impaired respiratory function.

Traditional treatment

Traditional medicine has still not lost its relevance and in some cases they are used to treat urticaria.

Some options are discussed below:

Hot shower as well as rubbing with freshly squeezed lemon juice or an alcohol solution helps reduce itching.
Rubbing with infusion of string, as well as a decoction of chamomile or oak bark is practiced after relieving acute symptoms to eliminate remnants of the rash.
Drinking one teaspoon of natural bee honey in the morning or royal jelly in a volume of no more than 5g. This procedure must be carried out before eating.
Infusion based on yarrow taken orally, the procedure is repeated 3-4 times a day, the dosage is no more than 70 ml during each dose. To prepare the product, you will need to dilute one tablespoon of dry herb with 200 ml of water, previously brought to a boil.
Evening warm baths, to which he adds 0.5 liters of infusion based on St. John's wort or celandine.
A product obtained by mixing equal proportions of tinctures of valerian, hawthorn and desert, which can be purchased at any pharmacy. Every day you need to take 30 drops of this mixture, the procedure is carried out before bed.

In what cases is emergency assistance required?

There are a number of cases in which urgent seeking professional medical help is required.

Among the main alarming symptoms are:

Respiratory dysfunction.
Loss of consciousness.
Lack of positive dynamics.
Feelings of nausea occur.
Localization of the lesion in the neck or face, as well as rapid progression of swelling in these places.

Why is urticaria dangerous in adults?

Hives itself does not pose a serious threat to humans, but some of its consequences can be extremely dangerous.

Among the main complications are:

Quincke's edema, which can lead to suffocation and death of the patient. You can look here.
Infections with various fungal and bacterial infections that enter the body through wounds on the scratched surface of the skin, which leads to the formation of boils and ulcers.

When the first alarming symptoms or suspicion of complications appear, you should immediately call an ambulance. Before her arrival, the patient is provided with first aid depending on the symptoms that arise.

Prevention

The preventive measures discussed below can minimize the risk of urticaria in people prone to this disease:

Avoid any contact with allergens.
Following a diet that excludes potentially dangerous dishes and products.
Maintaining a healthy lifestyle, completely giving up bad habits.
Taking comprehensive measures to strengthen the immune system.
Compliance with the measures necessary to prevent exacerbation of chronic diseases, especially if they are related to the functioning of the digestive system.

To summarize, it can be noted that urticaria in itself is not a dangerous disease, but many people aggravate the situation by independently prescribing treatment or failing to take timely measures, which can lead to serious complications.

When the first symptoms appear, you should immediately seek help from specialists before the lesions have spread throughout the body.

People at risk should teach their relatives how to provide first aid in the event of a possible exacerbation. Compliance with these simple rules greatly increases human safety and facilitates the process of treating the disease.

If the skin begins to itch and pimples appear on it in places, like nettles, you should seek help from a medical facility. Such rashes may indicate a number of health problems: from allergies to disorders in the functioning of human internal organs.

Urticaria is a human autoimmune disease that causes nettle-like blisters to appear on the skin. Additional symptoms are added to the main ones:

human body temperature rises;
chills, nausea, increased excitability, insomnia appear;
Some parts of the face and body may swell.

Urticaria in children and adults can last from one to one and a half months and up to ten years.

Manifestations of urticaria in a child are the result of exposure to a number of external factors on the skin:

allergic reaction to food, cosmetics, plants, animals, insect bites, cold, etc.;
infection with worms;
bacterial infection, herpes virus;
taking medications for a long period of time;
disruptions in the functioning of the endocrine system, gastrointestinal tract, and cardiovascular system;
stress, excessive physical activity, emotional overload.

The video tells everything about urticaria.

Types of urticaria in children

If a rash similar to a nettle burn appears on your baby's body, it is important to visit the office of a qualified dermatologist. The doctor must determine which type of similar disease manifested itself in the small patient.

Dermographic urticaria

The demographic type of urticaria often occurs in children who wear synthetic, tight clothing. Those areas of the skin that are susceptible to friction and pressure are more likely to scratch and develop a rash. The blisters take on the appearance of a strip placed in the direction of exposure to tight clothing. For example, the tight elastic band of sweatpants or the neck of a tight golf shirt.

Let's celebrate! If pimples appear and are itchy, under no circumstances should they be punctured or scratched, otherwise a surge of infection may occur. This aspect is extremely important to convey to parents and the baby himself.

When treating the disease you need:

protect the skin of a sick baby from exposure to traumatic factors;
take a course of 2nd and 3rd generation antihistamines.

Cholinergic urticaria

Cholinergic urticaria is often characteristic of young children: blisters appear on the child’s skin, the skin turns red and itches very much. The clinical picture becomes clear 5-60 minutes after active games, a hot bath, or a walk in damp weather. The rash concentrates on the face and skin of the upper body.

Important! Scientists have found that a similar reaction in a child’s body manifests itself under strong emotional stress, as well as the presence of pathologies of the digestive system and thyroid gland.

Treatment includes:

following a hypoallergenic diet;
taking antihistamines;
selection of clothes for the baby according to the weather;
monitoring the level of physical activity of the child.

Idiopathic urticaria

The idiopathic type of the disease manifests itself in children after sleep: the skin turns red, itching, and a rash appear. The main reasons for the appearance in most cases are associated with autoimmune processes characteristic of the body of a small patient. With chronic urticaria, blisters will periodically appear on the skin and disappear after a course of treatment.

Urticaria pigmentosa

Pigmented urticaria appears as purple spots that form in place of the original blisters. The main cause of the disease lies in the excessive accumulation of mast cells in the skin and internal organs of babies.

Urticaria pigmentosa is treated symptomatically:

the doctor will prescribe an antihistamine with cetirizine, systemic, local corticosteroids;
Sometimes treatment with cytostatics, for example Fluorouracil, or photochemotherapy is indicated.

Let's sum it up

Children suffer from hives more often than adults. The main reasons for this are: allergic reactions to external factors, tight clothing, emotional overload, etc. The problem must be treated immediately after its manifestation so that it does not develop into a chronic form of urticaria.

Urticaria is a disease that occurs quite often. From 10 to 35% of people have encountered it. In most cases it is acute. Let's try to figure out what urticaria looks like and what are the causes of its occurrence.

What is urticaria

Urticaria refers to a whole group of diseases that are caused by different reasons, but have the same manifestations on the skin. The appearance is similar to a nettle burn on the skin; itchy pink or red blisters have clear boundaries and turn pale when pressed.

Types of urticaria

Based on clinical manifestations, there are 3 types of urticaria.

Acute form characterized by the sudden appearance of a rash, the blisters are most often round, they often merge together, the skin lesions are quite extensive. A special case is this. In a patient, urticaria spreads to a limited area of the skin or mucous membrane. The affected areas turn white and become dense to the touch. Quincke's edema goes away within a few hours, sometimes lasting up to 1-2 days. If it occurs in the larynx, the patient is at risk of narrowing and suffocation.

Chronic phase may occur if the acute stage transitions to a recurrent one. Then the disease manifests itself through periods of remission, when the person seems healthy at this time, and periods of exacerbation.

Manifestations of persistent papular urticaria arise in places of long-lasting rashes, the stage of papules begins. The affected areas undergo pigmentation, changes in the stratum corneum of the epidermis leads to keratinization. Papular nodules are often found on the folds of the arms and legs and have a reddish-brown tint.

Hives have various causes. Physical is caused by exposure to irritants on the skin. The following types of physical urticaria are distinguished:

demographic, the cause of which can be various skin irritants, resulting in light scratches and minor damage to the skin. In this case, the blisters spread in the direction of scratching and have the shape of stripes. Such urticaria can occur on any part of the body, but it is less common on the face
slow, which manifests itself when the skin is compressed (sitting for a long time) after a few hours. Occurs on the part of the body that has received pressure. Pale pink, free-form blisters go away on their own after a while
cold(skin reaction to cold air, wind or food). Volumetric pale pink itchy blisters appear on the skin, which disappear within half an hour after warming up. This type of urticaria is often accompanied by angioedema; the increased risk of developing anaphylactic shock when swimming in cold water lasts a lifetime. The skin's reaction to cold may be accompanied by disruption of the central nervous system (dizziness), respiratory system (bronchospasm), gastrointestinal tract (vomiting, diarrhea), circulatory system (change in blood pressure)
thermal(under local thermal influence). The rashes are mostly small on congested skin, often accompanied by diarrhea and headache
solar caused by ultraviolet radiation. The red blisters often coalesce and hives resemble a sunburn. Additional body reactions (bronchospasm, decreased blood pressure) rarely develop. symptoms go away if you keep your skin away from the sun for a few days)
vibration, which occurs under the influence of vibration (when working with a jackhammer). The main symptoms are itching and redness of the skin, which do not require special treatment.

The following types are discussed separately:

Causes

In adults and children, urticaria can be caused by various reasons.

Taking medications: antibiotics (penicillin), non-steroidal anti-inflammatory drugs (aspirin), hormonal contraceptives. Sometimes the reaction appears after a few days
Food consumption: honey, fish, seafood, eggs, nuts, some fruits. In this case, urticaria usually occurs in children
Contact with certain substances: latex, household chemicals
Insect bites: wasps, bees, mosquitoes. Hives at the site of the bite sometimes persist for a day

Certain diseases can trigger the development of urticaria:

Physical reasons: sunlight, vibration, pressure, water, heat, cold, physical activity.

Symptoms of urticaria in adults and children

Adults may experience increased body temperature, malaise, and headache. Hives manifest themselves as bright pink or red blisters, clearly defined, ranging in size from a few millimeters to 10 cm in diameter. When the skin is stretched, the blister disappears. After some time, due to compression of the capillaries, the blisters turn pale. They can have any shape. Itching can also occur in areas where there are no rashes. It intensifies in the evening and at night. Pain and burning are characteristic of Quincke's edema.

It is easy for parents to notice even the onset of the disease in their children. It begins without previous symptoms, and acute stages of the disease predominate. Urticaria is accompanied by severe itching and is rare in children under six months of age.

The rash can be located on the mucous membrane (gastrointestinal tract, lips, eyes). The most dangerous is Quincke's edema in the larynx. The child develops a cough, breathing becomes difficult, and suffocation may occur. Swelling in the gastrointestinal tract is accompanied by diarrhea and nausea. The course of the disease is accompanied by nervous weakness, irritability, and dizziness. The temperature can rise to 39 degrees. There is a risk of the acute form becoming chronic, so do not postpone a visit to the doctor.

Treatment

First, you need to avoid contact with an irritating factor (taking medications, exposure to physical factors, etc.). Secondly, start drug treatment: taking antihistamines should start with a minimum dosage. If they do not help, then use hormonal medications (prednisolone). In severe cases, your doctor may prescribe immunosuppressants. Ointments containing hormones and non-hormonal ones are also used. read with us.

Hospitalization and treatment under the supervision of a physician may be necessary. The regimen eliminates contact with allergens, stress, and physical activity. It is necessary to detoxify the body and follow a hypoallergenic diet. Treatment in hospital may take 5-10 days.

You should not ignore hives, even if it occurs once. If the rashes recur, then you need to consult a doctor who can prescribe proper treatment. Do not forget that this disease can have many causes. Read more about it here. Hives are a possible symptom of a more serious condition. Take care of your health!

They appear in the form of blisters. Externally, the skin looks like it has been “scalded” by nettles. Hence the appropriate name.

If hives break out, redness is pink color And size from 1 mm before several cm, when pressure is applied to them they turn pale. The most unpleasant thing is that rash in the form of urticaria unbearable itches. Not only individual areas are affected, but the entire body.

Urticaria is a skin rash that accompanied fever, weakness, headaches.

Nature of the rash urticaria is divided into types:

Spontaneous urticaria appears without exposure to a visible irritant. If it is accompanied by difficulty breathing, you need to call an ambulance.

Causes and symptoms

The manifestation of symptoms depends on the form of the disease.

Urticaria rash - description of the causes:

Localization and nature of the rash

The clinical manifestation of the disease can vary, but the main symptom is rash and itching. The rash takes the form of small, blistered blisters.

Localized urticaria, description of the rash: if you examine it in magnification, you will see a dense oval bubble with clear boundaries. The color can range from pale pink to white-violet.

The rashes have the following characteristics:

unexpected rapid appearance;
ephemeral disappearance;
existence up to 24 hours;
peripheral growth and fusion.

The rash (urticaria on the body) can be located either on individual affected areas, which are characteristic of a particular type of disease, or on the entire area of the patient’s body. If the allergy is caused by a specific allergen, a rash will cover areas that come into contact with it.

Rashes due to chronic pathology

Chronic form characterized by frequent relapses. As a rule, exacerbation states occur unexpectedly. The rash appears without objective reasons.
