medicine, pollen of some plant, etc.), it’s not
will affect your well-being. Contact launches in the body
chain of reactions that ends only in 10-14 days.

allergen interaction may cause you pathological
reactions – including the appearance of spots on the body. Currently,
There are three known allergic diseases that are manifested by this.

  • Hives;
  • Dermatitis atopic character;
  • Eczema.

Their manifestations are slightly different, but the red spots
allergies always have common features:

  1. Body spots appear after repeated contact with
  2. They are accompanied by itching, which is aggravated by contact with
    an allergen. If the patient is isolated from the irritating substance,
    itching somewhat subsides, but does not pass immediately;
  3. The absence of other symptoms – the general condition of the patient with
    allergic diseases should not suffer. Temperature stays in
    within normal limits, appetite is preserved, and there is no weakness;
  4. If the body is covered with red spots, and they are gone after
    adequate therapy (or independently), they will arise again when
    повторном взаимодействии с an allergen. That is why the main
    method of treating allergies – eliminate the irritating substance from life
    the patient.

To accurately identify allergic disease, you need to
pay close attention to the appearance of the rash and observe,
how much it is stored on the body. The listed signs will be
quite enough for a primary diagnosis.

Rash with urticaria

This form often leads to red spots on the body.
baby In adults, it is much less common. Distinctive
urticaria feature is its favorable course – how
As a rule, the disease begins quickly and passes quickly (during
1-2 days). Only in isolated cases, it takes a protracted
nature and can persist for months and even years.

  • Rashes can be of various sizes and shapes, but
    large red spots similar to bites appear predominantly
  • Despite то, что болезнь продолжается несколько суток, сыпь
    constantly changing its location. The spots disappear over
    several hours, however new elements appear again and
  • Rashes somewhat rise above the skin and intensely

10-13 years, the affected areas begin to “get wet”, because

Allergic Eczema

Determination of eczema is the most difficult because this allergic
the disease goes through several stages that differ significantly
on external manifestations. First, there are red spots on the body,

certain time (from several days to 3-4 weeks) they begin
soak and slightly bloody. Last stage of formation

Diagnosis doctors use the following symptoms:

    (increases / decreases). Normal touches can cause
    inadequate response – severe pain or lack of sensation. it
    associated with damage to the nerve endings.

rashes that itch, scaly or even hurt (with prolonged

allergens: household and industrial dust, pollen, wool, dandruff and
etc. If the patient has one of these substances (or several)
reaction, in the form of redness, itching or small swelling – sample
considered positive.

As a rule, these actions are enough to identify the allergen.
If all tests are negative – doctors can increase
amount of substances to check. With the failure of diagnosis,
