Overview

Dyshidrosis is a skin condition that causes small, fluid-filled blisters to form on the palms of the hands and sides of the fingers. Sometimes the bottoms of the feet are affected too.

The blisters that occur in dyshidrosis generally last around three weeks and cause intense itching. Once the blisters of dyshidrosis dry, your skin may appear scaly. The blisters typically recur, sometimes before your skin heals completely from the previous blisters.

Treatment for dyshidrosis most often includes creams or ointments that you rub on the affected skin. In severe cases, your doctor may suggest corticosteroid pills, such as prednisone, or injections. Dyshidrosis is also called dyshidrotic eczema and pompholyx.
