Itching
Key Points
Itching can result from a variety of different causes, and each cause requires different treatment. If the person has no rash or skin abnormalities, the cause may be a systemic disorder, a nerve problem, or a drug or medication reaction. Skin care measures (such as limiting bathing, moisturizing the skin, and humidifying the air) help relieve itching when it is caused by dry skin. Itching can usually be relieved by topical or systemic treatments.
