Eczema is the most common type of dermatitis.  Eczema first appears as an episode of itching, redness and tiny bumps or blisters.  Most are related to allergies or to contact with irritating chemicals.  Each type of eczema also has specific characteristics and pattern of symptoms.  Your doctor usually can help whenever you have an area of skin that is red and very itchy, or skin that is cracked, blistered or painfully dry. You should ask your doctor for an urgent evaluation if you have signs of infection.

In general to prevent eczema flare-up by avoiding exposure to extreme temperatures, take a bath in warm water, leave a little moisture on your skin and apply a moisturizing cream or lotion to trap moisture in the skin after bathing, try to choose clothes materials made by cotton etc.

Eczema may be triggered by exposure to allergies.  Should call a professional doctor to get help.
