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. Eczema is often confused with psoriasis as both cause a dry and bumpy skin rash but it typically causes more intense itching than psoriasis. Eczema is a long-term skin condition more commonly seen in young adults. It 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, they dry up and the skin often becomes red and peels. This process can leave the toes tender and quite dry and sometimes results in painful cracks or fissures. Cracks in the skin may become infected.

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. Washing feet daily with a mild and fragrance-free soap and then applying a rich emollient with active ingredients like urea and ceramides while the skin is still moist, will keep skin in good condition. If eczema is inflamed and bothersome, it is best to seek the advice of a primary care professional or a Chiropodist or Footcare Nurse. A topical corticosteroid may be required to reduce inflammation and increase comfort. Eczema that has caused the skin to break or crack can also lead to fungal and bacterial infections, which should be treated with topical antifungals and antibacterials to prevent further complications. Oral medication may be required if eczema is severe and affects activities of daily living.
