WHAT IS AN ITCH?
Itch is an irritation in the skin that elicits an urge to scratch. Itches are a common problem and can be localized (limited to one area of the body) or generalized (occurring all over the body or in several different areas). The medical term for itching is pruritus. Generalized itch, for obvious reasons, is more difficult to treat than localized itch. Itches can also occur with or without skin lesions (for example, bumps or blisters). An itch that is accompanied by visible skin abnormality usually should be evaluated by a physician and, in some cases, by a dermatologist since the problem is likely to be a condition that requires specialized medical treatment (for example, eczema, scabies, etc.). What causes itching? Itching can be caused by many conditions. Probably the most common cause of itch is psychological, that is, due to stress, anxiety, etc. Stress also can aggravate itch from other causes. Dry skin is another frequent cause of itch. Many people also report sunburn itch follo
