Dyshidrosis; Pompholyx
Small fluid-filled blisters called vesicles appear on the hands and feet. They are most common along the edges of the fingers, toes, palms and soles. These blisters cause intense itching.
Scratching leads to skin changes and skin thickening. There may be cracks on the fingers or toes.
Large blisters may cause pain.
Your doctor may often diagnose this condition by simply looking at your skin.
Sometimes, a skin biopsy or skin scraping may be needed to rule out other causes.
