Short-term symptoms of eczema include itchy skin, redness and tiny bumps or blisters.
If these symptoms remain untreated, the skin can become thick, scaly and dry. There can be areas of hair loss and color changes. Skin affected by long-term eczema is more vulnerable to secondary infections.
Each type of eczema has specific characteristics and patterns of symptoms:
When triggered by an allergic reaction, it usually causes skin redness, fine red bumps or blisters and severe itching.
A reaction caused by plant allergies (like poison ivy or poison oak) is usually intense. It appears as bumps and blisters in lines or streaks where the plant brushed against the skin.
Patches appear most commonly on the scalp as dandruff. But they also can occur elsewhere on the body. They may appear on the eyebrows, eyelids, ears and skin creases near the mouth and nose.
Scalp lesions in infants (cradle cap) can appear yellowish and greasy. They usually cause no discomfort.
