Eczema on the feet is known as dyshidrotic eczema, a type of eczema that causes small blisters on the palms of hands, soles of 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. The heels of the feet endure the weight of the and pressure during gait which can make eczema worse. Eczema is a long-term skin condition more common 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. This process can leave the heels feeling tender and may even lead to painful cracks or fissures in the skin. A break in skin such as a crack increases risk for infection.

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. Sweaty feet may aggravate eczema, especially if the feet are in contact with sweat-moistened socks and shoes for prolonged periods of time.

Treatment
It is important to know what triggers or exacerbates eczema. This will help avoid a flare-up. The combination of washing feet daily using a mild and fragrance-free soap and applying a rich moisturiser containing urea when the skin is still moist, will maintain the moisture balance of skin. 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 there are cracks in the skin, 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.
