Dyshidrotic eczema causes small blisters that develop on the fingers, palms and soles of the feet. It can be due to exposure to cobalt or nickel, fungal infections, allergies and excessive stress. The affected area becomes thick and scaly, severe itchiness, redness and inflammation. Women are more susceptible to this condition than with men.
Dyshidrotic eczema blisters usually erupt during seasons of spring allergy. The blisters can last for 3 weeks before they start to dry up and sometimes they can become large and cause pain. Once the blisters dry up, the skin may crack where it starts to feel dense and sponge-like, particularly after the area has been scratched.
