Dyshidrosis refers to a skin condition that causes small water blisters on feet, palms of the hands, and the sides of the fingers. These blisters are especially common on the foot because of friction from ill-fitting shoes. This causes skin damage, and a blister develops to protect the region as the skin undergoes the healing process.
Dyshidrosis is a chronic type of eczema that causes a person to experience burning and itching sensations for a few weeks. In some cases, blisters reoccur before the skin can heal completely from previous blisters.
Other names for this skin inflammation are dyshidrotic eczema, pompholyx eczema, cheiropompholyx, pedopompholyx, acral vesicular dermatitis, and chronic hand dermatitis.
It is most likely to appear to those who are between the ages of 20 and 40.
