Athlete’s Foot: Causes, Symptoms, and Treatment
Athlete’s foot, also known as tinea pedis, is a common fungal skin infection that affects the feet. It most often develops between the toes, but it can also spread to the soles of the feet and toenails.
Fungus thrives in warm, dark, and moist environments—making shoes an ideal place for it to grow. Because other skin conditions, such as eczema or psoriasis, can look similar, athlete’s foot should be properly diagnosed to ensure the right treatment.
What Causes Athlete’s Foot?
Athlete’s foot is caused by a fungus that grows in damp areas. Common places where the infection is picked up include:
- Public showers
- Locker rooms
- Pool areas
The condition became known as “athlete’s foot” because athletes frequently used these shared facilities, increasing exposure to the fungus.
Symptoms of Athlete’s Foot
Symptoms may vary from mild to severe and can include:
- Dry, cracked, or scaly skin
- Itching or burning, especially between the toes
- Peeling skin
- Redness, swelling, or inflammation
- Blisters that may crack and cause soreness
Athlete’s foot can spread to other areas of the foot, toenails, or even other parts of the body if scratched and touched elsewhere.
When to See a Podiatrist
If symptoms do not improve within two weeks despite proper foot hygiene and over‑the‑counter treatments, it’s important to see a podiatrist. Professional care helps prevent the infection from spreading or becoming chronic.
Diagnosis and Treatment
Your podiatrist will examine your feet to confirm whether the infection is fungal or bacterial. If athlete’s foot is diagnosed, treatment may include:
- Prescription antifungal creams or sprays
- Oral antifungal medication for more severe cases
Following the full course of treatment is essential. Stopping medication too early often leads to treatment failure or recurrence.
If the infection is bacterial rather than fungal, antibiotics may be prescribed.
Your podiatrist may also recommend:
- Keeping feet clean and dry
- Using antifungal foot powder in shoes and socks
- Thoroughly drying between the toes after bathing
If someone in your household has athlete’s foot, disinfect shared showers and tubs to reduce the risk of spreading the infection.
