People with eczema are familiar with itchy, inflamed skin. Athlete’s foot — a common rash on the feet — can also cause irritation and itching. When your feet are itchy and inflamed, even if you’ve had eczema for years, it can be hard to tell what’s causing it. “My fingers and the bottom of my feet have itched all night. Wearing shoes has been terrible. I thought it was athlete’s foot at first,” one MyEczemaTeam member shared.
Athlete’s foot and eczema can both cause itchy, sometimes painful, rashes as well as cracked and peeling skin. So, when you develop an itchy rash on your feet, how exactly can you tell which condition you have?
Athlete’s foot is a contagious, fungal infection caused by dermatophytes — the same fungi that cause ringworm. It’s also known as tinea pedis — “tinea” meaning ringworm and “pedis” meaning foot. It is a common condition with approximately 70 percent of people at some point in their lives.
Eczema is a chronic (ongoing, or long-term), noncontagious skin condition. Doctors aren’t sure what causes eczema. It may be caused by a gene variation, weakness in the outer layer of skin (the skin barrier), an inflammatory response, or other causes.
The fungi that cause athlete’s foot thrive in warm, humid conditions, such as damp socks. It spreads through direct contact (skin-to-skin), contact with a flake of skin, or via contaminated surfaces, such as shoes and towels. Common places to contract athlete’s foot include locker rooms and saunas. Cleveland Clinic notes that men and people aged 60 or older have a higher risk of developing athlete’s foot.
Eczema may run in families. It’s particularly common in infants and children. According to the National Eczema Association, approximately 80 percent of people with atopic dermatitis — the most common form of eczema — will have symptoms before they’re 6 years old. Eczema is associated with other immune system conditions, like allergies and asthma. For example, more than half of children with severe atopic dermatitis will develop asthma.
Dyshidrotic eczema, also called pompholyx or vesicular eczema, is a type of eczema that presents as tiny, fluid-filled blisters. It typically affects the palms, soles of the feet, and the sides of the fingers. It’s most common in those aged 20 to 50 years old but can develop at any age.
Health experts still don’t know the cause of dyshidrotic eczema. However, you may be at increased risk of dyshidrotic eczema if you smoke, are undergoing radiation therapy, or if you have:
Exposure to different irritants, including allergens, may trigger eczema flares. Common triggers include soaps, detergents, lotions with fragrance, cosmetics, dust mites, and pet dander.
Common symptoms of athlete’s foot are itchiness, burning, and stinging. The way athlete’s foot looks can change depending on the type of infection — a toe web infection, vesicular-type, moccasin-type, or ulcerative infection. Athlete’s foot may appear as:
Eczema often presents with:
After initial itchiness, dyshidrotic eczema may cause small blisters, which can be extremely itchy and painful. These blisters may grow larger and typically last a few weeks. If you have dyshidrotic eczema, you may also notice:
The location of eczema can vary depending on age and other factors. Children under 2 often develop atopic eczema on the cheeks, stomach, arms, and legs, while adults typically see it on the face, hands, neck, and in the folds of the elbows and knees. However, different types of eczema can affect any part of the body. Dyshidrotic eczema, for example, usually appears on the palms, soles, and sides of the fingers.
Typically, your health care provider diagnoses athlete’s foot based on your symptom history and a foot exam. In some cases, further testing may be needed. If necessary, your provider will perform a biopsy, removing a tiny piece of skin for lab testing.
Your general health care provider can diagnose eczema with a physical exam and by asking questions about your health and symptom history. Mention any contact you’ve had with potential irritants. Before diagnosing you with eczema, your health care provider will rule out other causes of your rash, including autoimmune diseases, allergic contact dermatitis, and athlete’s foot.
Diagnostic testing for eczema may include:
When one member of MyEczemaTeam experienced eczema on their feet, they asked, “Can I use athlete’s foot cream on my eczema? It’s prescription cream.”
Since eczema on the feet and athlete’s foot have similar symptoms, it may be tempting to treat them with the same products. However, these conditions have different causes and need different treatments.
Athlete’s foot is typically treated with topical antifungals (over-the-counter or prescription). You can find topical antifungals in many forms, including:
Alternatively, your health care provider may prescribe oral (taken by mouth) antifungal medications to treat your athlete’s foot. Typical oral antifungals include itraconazole, fluconazole, and terbinafine.
Other ways to manage athlete’s foot include:
You can treat eczema with daily applications of moisturizers and ointments, such as petroleum jelly. Treat infant eczema with moisturizing, bathing, and other at-home practices.
Prescription treatments for eczema:
Side effects of prescription treatments can vary, so it’s important to ask your doctor about any you might experience.
To treat dyshidrotic eczema, apply moisturizing cream or lotion every day. Other options include:
If an area affected by eczema becomes infected, treatment will depend on the type of infection.
With the right diagnosis and treatment, athlete’s foot should resolve within one to eight weeks. As your athlete’s foot begins to heal, symptoms such as itchiness will become less bothersome. However, it’s important to complete your prescribed treatment. Stopping treatment early can cause your athlete’s foot to come back in a harder-to-treat form.
Many children outgrow eczema. For others, eczema is an ongoing condition — symptoms will flare and improve over time. Your health care provider can help you find the most effective long-term therapy.
You can help prevent athlete’s foot by practicing good foot hygiene:
You can help prevent eczema flare-ups by moisturizing daily after bathing. Your health care provider may also suggest avoiding:

The tips mentioned earlier for managing general eczema also apply to dyshidrotic eczema. In addition, your health care provider may suggest the following specific measures:
It’s important to know when to seek medical advice for athlete’s foot and eczema, especially if symptoms persist or worsen. Here’s when to consult your health care provider for each condition.
For athlete’s foot:
For eczema, consult your health care provider if:
If you’re unsure about your symptoms or if your treatment isn’t helping, reach out to your health care provider. They can help you find the right way to treat your condition and prevent it from getting worse. Receiving the right care early on can make a big difference in managing your symptoms and improving your comfort.
