What is eczema

Eczema is a rash that appears on the face, behind the knees and on the inner sides of the arms and wrists. It is an itchy, dry and scaly rash. In a very bad case, it may ooze profusely. It can be caused by a cold, a sleepless night or an upset stomach. Infantile eczema is often linked to asthma. They are both allergic conditions and are very likely to be hereditary.
