Symptoms of hives

The rash characteristic of allergy urticaria, very specific - if you see it at least once, you will never go wrong. But for those who have not had the good fortune to witness an eruption of urticaria, we describe the clinical course of this allergic reaction.

Rash in the development of hives strong enough rises above the surface of the skin - 3-5 millimeters. Rash itself looks well-defined blisters, exactly like contact with nettles. These blisters can be very different color - from pale pink to bright red. For this rash is characterized by the following feature - if you click on the blister, it will become normal skin color and disappear. But it is necessary to let go, as immediately appear again.

Dimensions blisters can also be very different - from a couple of millimeters to several centimeters, and the number of lesions themselves can vary from single to multiple, covering almost the entire surface of the skin of the body. Typically, if a lot of lesions, they merge into a large spot diameter of several to tens of centimeters. Probably it would be superfluous to say that the rash hives unbearable itch.

Depending on the time during which the stored rash, doctors distinguish two forms of the disease course:

  • The acute form of urticaria

In this form of the disease symptoms develop very, very quickly - within one hour after exposure to the allergen. Typically, a lot of blisters, they are large in size and very itchy. Symptoms disappear quickly - a maximum during the day after the removal of the allergen.

  • The chronic form of urticaria

If you are "lucky" to face with chronic allergy urticaria, the picture of the disease will be somewhat different. First, the disease develops gradually - every day you discover all new rashes and old will disappear. Although, of course, lesions in the chronic form is much less than in the acute form. Persist such chronic urticaria can be a very long time - weeks or even months. The most common of such allergic dermatitis affects middle-aged women.

Pseudoallergic urticaria

Very often, doctors have to be differentiated from allergic urticaria pseudoallergic. In the second case, the development of cutaneous lesions does not occur due to allergen exposure, and due to the presence of certain diseases. Such diseases include:

  • The presence of parasites in the body.
  • Hepatitis A and B.
  • Tuberculosis and sepsis.
  • The presence of tumors in the body - of both benign and malignant.
  • Problems with the endocrine system.
  • Systemic lupus erythematosus, rheumatoid arthritis.

Outwardly this hives pseudoallergic virtually no different truth. However, blisters slightly smaller, and they are almost always localized at the back and abdomen, while an allergic urticaria affected body without exception. However, precisely identify the type of urticaria, of course, only by a doctor.

Diagnosis of allergic urticaria

In the diagnosis of urticaria is no big deal, and distinguish it from any other skin rashes can all medical students. However, this is not the most important task - is much more important to find out why this is the allergic reaction manifested itself. After all, without knowing the cause, it is difficult to limit contact with the allergen, and hence the repetition of an attack of hives.

  • Location rash

First the doctor will pay attention to where the hives rashes - if on the open areas of the body, can be suspected cold allergy or an allergy to the sun's rays. Of course, at the same time take into account the history - if you have not been on the street a few days, you can hardly suffers from the weather, whatever it was.

  • The conversation with the patient

By the way, history was very important - allergist should be very careful to ask the patient or his or her parents if allergic urticaria develop a child. Perhaps people have recently eaten something unusual, any product that is not in his daily diet? Or maybe you changed laundry detergent? Or bought a new hand cream? It is important to remember all the details - details not and can not be, so tell your doctor about even what you think is not worth any attention. Very often, such a conversation can quickly identify the source of the troubles - the allergen that provoked allergic urticaria.

  • Allergic tests

In the event that a conversation with a patient proved inconclusive, the doctor is likely to take a decision on the need for allergy testing. This can be a blood test that detects allergens or skin tests - depending on the specific case. Skin testing is done as follows: using a special needle on the surface of the skin doctor makes scratches. They are then applied saline, containing various allergens. After about 20 minutes, the doctor will assess the results - if the skin around the scratch reddened and / or swollen, a person is allergic to the substance, it is dissolved in the liquid. Unfortunately, sometimes there are cases where the true cause of an allergic reaction to install and it is impossible.

If a person suffers from chronic urticaria, diagnosis should be more extensive. First, you must pass a general analysis of urine and blood tests, liver function tests, tests to determine that the absence of parasites, eliminate dysbacteriosis, conduct ultrasound of internal organs, X-ray examination of the lungs, and a number of other studies. Such a detailed examination is necessary in order to identify the disease, provokes the development of hives.

Treatment of allergic urticaria

Ignore allergic urticaria can not in any case - the treatment should start immediately after the onset of symptoms. We have already talked about the fact that the true allergic urticaria to get rid of the acute form is not so difficult if you know what to do.

  • Avoid contact with the allergen

The first and most important condition for the treatment of hives - the removal of the allergen. Surely, surely it can be done only if you know exactly what you are allergic. Otherwise eliminate all possible allergens, which have already been mentioned.

  • Antihistamines

If rash enough, do not stop taking antihistamines. Ideally, a medicine to help you choose the allergist. But if the opportunity to consult with a doctor you do not, you can purchase at the pharmacy or tavigil suprastin. Strictly follow the recommended dosage - it exceeded quite a negative effect on the body. Moreover, the drug has to be a one-off, as emergency aid. Continue treatment only after a visit to the doctor, if need be.

  • Local media

Eruptions cause very intense itching, which suffer very, very difficult. In order to get rid of it, you can use ordinary zinc ointment, which is sold in every pharmacy. Just apply a thin layer of ointment rash and leave it on for 20-30 minutes, then rinse with water. If the situation is critical, the doctor will prescribe you a more potent ointment, which include corticosteroids.

There are many different recipes of traditional medicine that promise quick relief from allergic urticaria. Doctors also categorically opposed to this kind of treatment, because almost all the recipes are based on the action of various medicinal plants. And without exception, any plant - a potential allergen. And when allergy can cause hives, even familiar plant that you have repeatedly used. Therefore, give up traditional medicine.

The only way that is worthy of your attention - it compresses with baking soda, which is very well relieve even the most severe itching. Compresses simple - you only need a gauze cloth and baking soda. From gauze cut into several small napkins and prepare saturated soda solution - dissolve in a glass of water five teaspoons of baking soda and mix thoroughly.

Dampen a soda solution gauze and apply to blisters, leave for 10-15 minutes. If the cloth dries before, change it to the moist. After the procedure did not take a shower even though an hour. Itching will disappear fairly quickly, and come back in about 3-4 hours. If this happens, you can once again make soda compress - it is absolutely safe for health.

Treatment of chronic allergic urticaria - the process quite laborious and lengthy, sometimes occupying more than one month. It goes without saying that the treatment regimen must be selected exclusively allergist. Most often it is receiving antihistamines, external agents, restorative measures and, of course, the elimination of exposure to the allergen. In any case, treatment will be prescribed by a doctor, taking into account the specific situation.
