Thanks for the question.
Dyshidrotic eczema is a form of eczema that presents as tiny bubbles on the hands and feet. The rash is often itchy and the tiny bubbles can become more confluent to form larger blisters. The rash can also be painful when the blisters burst and there are raw areas of skin.
It is important to avoid harsh soap and detergents and irritants as this can further aggravate the rash. Topical steroids and moisturizers are often prescribed to reduce the inflammation and control the eczema. This should be able to control the eczema in most cases.
Dyshidrotic eczema can be recurrent in many cases, with periods of improvement and exacerbation. In some individuals, the dyshidrotic eczema can be very severe and debilitating and topical creams alone may be unable to sufficiently control the condition.
In severe cases, phototherapy or oral immunosuppressive medications may be needed to control the eczema. These medications can help control the eczema but can lower the immune system and have other systemic side effects. Your doctor or dermatologist will discuss the risks and benefits of such treatments with you before commencing on them.
