Blisters on the skin with allergies: is this a dangerous phenomenon?

Allergy is one of the most common modern medical problems, and blisters on the skin are one of the symptoms of such a reaction. They often appear suddenly and cause a lot of inconvenience, but they can also quickly disappear. How to get rid of them, or even better to prevent such a problem?

Allergy symptoms and types of rashes

If a person is prone to allergies, he is well aware of symptoms such as watery eyes and a runny nose on contact with an irritant.

However, the coverage of signs is much wider:

  • swelling;
  • redness of the eyes;
  • hyperemia of the skin;
  • the appearance of a rash on the body;
  • itching;
  • temperature;
  • nausea;
  • sore throat;
  • shortness of breath.

It is the rash that is a clear sign of the problem. It should be borne in mind that they can be associated with other diseases, for example, parasite damage, diabetes, hormonal disruptions, infections, etc.

Blisters are a lump or blister of fluid on the skin.

There are several types of such formations:

  • small rash;
  • large bumps;
  • spots;
  • bubbles.

The most common rash allergy is hives. Pimples begin to itch, turning red. When pressed, the center remains white.

As a rule, blisters appear on sensitive areas of the body, where many capillaries are located.

These include:

  • wrists;
  • elbow and knee bends;
  • face;
  • stomach.

The rash can spread to the legs and arms, back and chest. Severe itching is not the only problem. With an acute reaction, severe intoxication may develop, as well as Quincke's edema.

Reasons for the reaction

A similar blistering reaction occurs when an allergen enters the body. In this case, both internal penetration (food) and the contact form of the disease (reaction to cosmetics, clothing material, etc.) are possible.

Blisters on the body are the result of the release of histamine into the bloodstream. In those areas where there are many capillaries, vascular permeability increases, and allergy mediators react. All this provokes tissue edema and the corresponding symptoms.

Most often, allergies occur as a result of exposure to:

  • food products (honey, eggs, nuts, citrus fruits, etc.);
  • artificial additives and preservatives;
  • cosmetics;
  • household chemicals;
  • medicines;
  • frost and wind;
  • ultraviolet radiation;
  • chromium and nickel;
  • an insect or animal bite;
  • animal hair;
  • costume jewelry;
  • plants;
  • clothing material, etc.

To successfully treat and prevent similar problems in the future, it is necessary to establish the exact cause of the allergic reaction. This can be done independently by observing the reaction of your own body to certain stimuli. An alternative option is allergy tests at a medical facility.

First aid

Allergy is a rather dangerous reaction of the body. If it is not stopped in time, a person risks his health, and sometimes his life.

As a first aid, follow these steps:

  • Eliminate the source of irritation. If this is not done, the problem will not go away. In addition to exacerbating symptoms, you run the risk of acquiring chronic urticaria;
  • It is necessary to drink an anti-allergic agent. It will block the production of histamine and relieve swelling. In difficult situations, the drug is administered intravenously;
  • Relieve skin irritation. It is necessary to calm the inflammation so that the blisters on the body do not start to fester.

  • Sedatives. Allow to relieve itching and relieve general tension, irritability;
  • Glucocorticosteroids. Eliminate discomfort, relieve inflammation;
  • Enterosorbents. They act on the cause of the allergic reaction from the inside, that is, they absorb irritating elements and remove them from the body, prevent intoxication. Used when eating food;
  • Calcium preparations and vitamins (A, C, E). They help to reduce vascular permeability, prevent the formation of blisters on the skin;
  • Antiseptics. For disinfection of the area of rashes. Additionally, you may need local anti-inflammatory drugs.

Their advantage lies in the fact that the body is not once again exposed to drugs and synthetic substances. At the same time, certain ingredients can provoke an even more negative reaction in the patient, since herbs are also potential allergens.

In order to get rid of blisters on the body and reduce itching, decoctions for baths and compresses, homemade ointments are used. In addition, they are also used to disinfect the surface of the skin, relieve inflammation.

  • Drinking alcohol. Sometimes allergies are directly related to the consumption of alcoholic beverages. In addition, during its treatment, drugs are used that are not allowed to be mixed with alcohol;
  • Glue a patch over the rash. You can make lotions with medicines, but you can't stick pimples for a long time. Bacteria can accumulate under the patch, and diaper rash can form. In addition, sometimes the adhesive used to make the patch also provokes allergies;
