- Summary
A foot rash can occur due to an allergic reaction or infection. A person can treat some rashes, such as athlete’s foot and contact dermatitis, with over-the-counter (OTC) medications. In some cases, prescription medication may be necessary.
However, other types of foot rashes, such as cellulitis may require medical intervention.
Tinea pedis, more commonly known as athlete’s foot, is a highly contagious fungal infection that develops on the feet.
A fungus called Trichophyton causes athlete’s foot. This fungus thrives in warm, moist environments, such as shower floors and the inside of shoes.
Athlete’s foot often leads to itchy, burning skin between the toes. Other symptoms of the condition include:
•dry, scaly, or cracked skin
•flushed or raw skin
•weak, discolored toenails
Treatment
People can avoid the substance that they think is causing contact dermatitis to see whether their rash clears within 1–3 weeks. Antihistamines and topical corticosteroids may help relieve symptoms.
Poison ivy, oak, and sumac grow in both wooded and marshy areas. These plants produce sap that contains an allergen called urushiol.
Urushiol can trigger an allergic skin reaction called contact dermatitis. About 50–75% of adults in the United States are allergic to urushiol.
Symptoms of a poison ivy, oak, or sumac rash include:
•flushed, itchy skin
•bumps or blisters on the skin
•swollen, tender skin
Dyshidrotic eczema, or dyshidrosis, is a common form of eczema that causes itchy blisters on the palms of the hands and soles of the feet.
According to the National Eczema Association, dyshidrotic eczema is twice as common in females as males.
Symptoms can include:
•deep blisters on the toes, palms, edges of the fingers, and soles of the feet
•flushed, itchy skin
•scaly, cracked, or flaking skin
Hand, foot, and mouth disease (HFMD) is a skin condition that occurs due to coxsackievirus and enterovirus infections. HFMD is highly contagious, and people can contract it by:
•touching a person with the infection
•touching objects or surfaces that carry the virus
•breathing air that contains the virus particles
Although HFMD is most common among young children under the age of 5, anyone can develop the infection.
HFMD usually leads to small spots appearing on the hands and feet, as well as mouth sores. Other symptoms include:
Cellulitis is a bacterial infection that develops in the deep layers of the skin and on the lower legs and feet. Symptoms include:
•skin that appears swollen
•skin that feels warm, tender, or painful to the touch
•skin dimpling
•blisters
•fatigue
Scabies is a skin condition that occurs when microscopic scabies mites burrow into the upper layer of the skin. These mites then feed on skin cells and lay eggs. Symptoms of scabies usually develop within 4–8 weeks.
A scabies infestation can lead to a skin rash and intense itching. The affected area of skin may develop pimple-like blisters or thick, crusty scales.
People should contact their healthcare provider if their foot rash is painful or significantly interferes with their daily activities.
Parents and caregivers should see a healthcare provider if a child or infant develops a skin rash or blisters.
There are numerous possible causes of foot rashes, ranging from allergic reactions to infections. Most cases clear up on their own, but OTC medications can help relieve swelling, itching, and pain during recovery.
A person should speak with a doctor if they have a foot rash that does not respond to treatment or they develop signs of an infection.
