The National Institutes of Health notes dyshidrotic eczema is a condition marked by small, itchy blisters that can develop on the skin of your hands and feet. Blisters are most likely to develop if you're under stress, because of allergic reactions, on hands that are often moist and in individuals who do cement work with their hands -- due to the chemical exposure. Dyshidrotic eczema blisters can lead to intense itching and scale-like patches on the skin that can become red and painful. Fortunately, there are ways to treat these itchy, skin blisters.
Consult your doctor. A doctor can diagnose dyshidrotic eczema by looking at your skin. A doctor may also take a skin biopsy to rule out fungal infections or an allergy test if he suspects the blisters are from an allergic reaction.
Use oral anti-itch medications. Medications -- such as diphenhydramine or loratadine-- can help to prevent itching. Take medications during the day and at night -- especially if you are prone to scratching while you sleep.
Apply ointments or creams. Apply twice a day and after you wash your hands. Petroleum jelly and mineral oil are heavy, slightly messy ointments, but can help ease itching and pain. Try over-the-counter lotions decided to help reduce itching when you do not have time to wait for heavy, messier lotions to dry.
Follow the advice of your doctor. Your doctor may prescribe steroid creams and phototherapy to help treat and reduce blisters.
