Causes and Treatment for Small, Itchy Blisters ------------------------------------------------------------------------------ QUESTION: I have a perplexing condition on my hand that seems to defy the talents of my local physicians. It starts with a group of small blisters forming only on both palms, that grow larger, and the skin grows red. After they leak, a crust forms, then dries up. The itch is constant, so that I am constantly scratching my palms. Any ideas on what it is and what I can do to rid myself of this constant annoyance? ------------------------------------------------------------------------------ ANSWER: You could be suffering from one of many things, particularly those skin conditions we call "dermatosis" or "dermatitis". Sometimes they result from merely coming in touch with substances that you are sensitive to, and are then classified as a contact dermatitis. However, your description of small blisters (called "vesicles" in medical nomenclature), and the fact that the rash only occurs on the palms, makes me think your problem is one called "dyshidrosis". It is a difficult condition to diagnose, and may not be thought about for its cause is unknown, and the onset of the rash is difficult to relate to other specific factors. Original investigators put the source of the trouble in the sweat glands, and so named it dyshidrosis (sweating disorder). Nickel is often suspected in cases of dyshidrosis, and you might wish to explore the possibility of contact with this or other noxious metals as you seek the explanation in your case. It is seen most frequently in persons aged 20 to 40, and women seem to be affected as frequently as men. It occurs more frequently in warm weather and nervous Type A personalities are more prone than others. It's hard to treat. Soaking the hands (or feet if that's where the rash occurs) for 30 to 60 minutes in cool water may relieve some of the symptoms. Usually a topical steroid cortisone like cream is prescribed, and white cotton gloves are recommended for wear after the cream is applied. Not only do they help in the process of healing, but might keep you from scratching your lesions. A softening or emollient cream is often used after the medicated cream is rubbed into place. In serious cases an oral corticosteroid is recommended, and a 1 to 3 week course of therapy is often enough to control the rash. Many physicians also recommend a series of relaxation techniques to reduce the mental and emotional stress that so often precedes the onset of the rash. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
