Eczema on the feet is known as dyshidrotic eczema, a type of eczema that causes small blisters on the feet and edges of the fingers and toes. It is also referred to as atopic dermatitis because it can be a sign of allergy. Unlike the tough and thick skin on the bottom of the feet, the skin on the top is thin and delicate. Friction from socks and shoes could worsen symptoms of eczema. Eczema is a long-term skin condition more commonly seen in young adults and can occur as a single flare-up in a person’s life or come and go for years.

Symptoms
Dyshidrotic eczema is a common form of eczema and is also referred to as pompholyx, a Greek derived word meaning “bubble.” This type of eczema only occurs on the hands and feet and usually begins with a painful rash of blisters or vesicles. As the blisters heal, the fluid inside them reabsorbs into the body. The skin will then become red and may start to peel. The top of the foot will likely feel itchy and irritated. Scratching to relieve itchiness can cause breaks in the skin which can lead to infection and significant pain and discomfort.

Causes
The cause of dyshidrotic eczema is unknown, but it is more likely to occur in multiple family members, suggesting a genetic link. Eczema is a form of atopic dermatitis because it is frequently triggered by the presence of an allergy. It can also be triggered by stress, heat and humidity, sensitivity to soaps and detergents and various metals such as nickel. The skin on the top of the feet is thin and delicate which makes it more susceptible to irritation and injury. If this skin is particularly dry, it is less resilient to friction and scratching.

Treatment
It is important to know what triggers or exacerbates eczema. This will help avoid a flare-up. Washing feet daily using a mild and fragrance-free soap keeps the surface of the skin clean. Applying a rich emollient when skin is still slightly moist will ensure the moisture balance of skin is maintained. If eczema is bothersome, it is best to seek the advice of a primary care professional or a medical footcare clinician. A topical corticosteroid may be required to reduce inflammation and increase comfort. If the skin is scratched, there is a risk for a fungal or bacterial infection. Infections may need to be treated with topical or even oral antimicrobials to prevent spread and further complications.
