The cause of dyshidrotic eczema is unknown. However, it can be associated with a skin disorder called atopic dermatitis, as well as seasonal allergies, such as hay fever.
Blisters also may appear on the soles of the feet. They often last about three weeks and itch intensely.
Treatment to clear up the blisters and relieve itching most commonly includes creams and ointments to rub on the affected areas.
