What Is Eczema?
Eczema is a term for a group of medical conditions that cause the skin to become inflamed or irritated. Itchiness is almost always a symptom of eczema, which either precedes or leads to the appearance of a rash that can occur on the face, back of the knees, wrists, hands, or feet. Pain, swelling, small blisters, and dry or flaking skin are also common symptoms of eczema.
