Athlete’s Foot (Tinea Pedis)

Athlete’s foot is a common fungal infection that typically begins between the toes. It is most often seen in people whose feet become excessively sweaty while confined in tight-fitting shoes.

Signs and Symptoms

• Itching between the toes

• Burning or stinging sensation

• Dry, scaly rash

• Cracked or peeling skin

• Redness and irritation

Athlete’s foot is contagious and can spread through direct contact with contaminated surfaces, towels, socks, or clothing. Common sources include locker room floors, public showers, and swimming pool areas.

Prevention

• Keep your feet clean, dry, and cool.

• Change into clean socks daily and avoid reusing socks.

• Wear flip-flops or shower shoes in public locker rooms and showers.

• Avoid walking barefoot in public areas.

• Keep toenails clean and trimmed short.

• Choose breathable footwear whenever possible.

Treatment

Most cases can be effectively treated with over-the-counter antifungal creams, sprays, or powders. More severe or persistent infections may require prescription antifungal medication. While treatment is usually successful, athlete’s foot can recur if preventive measures are not maintained.

Erythrasma

Erythrasma is a chronic superficial skin infection caused by bacteria. It is often mistaken for athlete’s foot because it can produce similar symptoms between the toes. The condition commonly affects skin folds throughout the body but is frequently seen between the fourth and fifth toes.

Causes

Erythrasma is caused by the bacterium Corynebacterium minutissimum.

Risk factors include:

• Warm and humid climates

• Excessive sweating

• Diabetes

• Obesity

• Advanced age

• Poor foot hygiene

Signs and Symptoms

• Brownish-red or pink discoloration of the skin

• Mild scaling

• Itching or irritation

• Skin changes between the toes, especially in the fourth interspace

Treatment

Treatment is typically straightforward and may include:

• Prescription topical antibiotics

• Thorough drying between the toes after bathing or showering

• Good foot hygiene practices

• Management of excessive sweating when present

With appropriate treatment, erythrasma usually resolves quickly, although recurrence can occur if contributing factors are not addressed.
