Sometimes a change in the weather or humidity causes eczema. Also, you may get eczema when you eat certain foods or take some medicines. The tendency for severe eczema generally seems to be inherited along with asthma or hay fever. The main symptom of mild eczema is a small area of fine, dry scales, often on the arms or legs. The skin may or may not itch.
Severe eczema causes intense itching.
The most common areas of itching are the fronts of the elbows, backs of the knees, and face. However, any area of skin may be affected. The skin is usually very sensitive to being touched. Even a light touch may cause itching. Many people who have severe eczema are quite sensitive to scratchy fabrics, especially wool.
