Dyshidrosis (also known as Dyshidrotic eczema or Pompholyx,) is a skin condition that presents as small, fluid-filled blisters on the palms and fingers of the hands or the soles and toes of the feet. With dyshidrosis, the affected skin becomes inflamed and the areas between skin cells open and fill with fluid. The blisters that occur last approximately three weeks and cause intense itching. Once the blisters dry, cracks form in the skin which can be unsightly and very painful.
Symptoms of dyshidrosis include
