Athlete’s Foot / Tinea Pedis

Athlete’s foot, also known as tinea pedis, is a common fungal infection that affects the skin of the feet, particularly between the toes. This highly contagious condition thrives in warm, moist environments and can cause itching, redness, cracking, and discomfort. While athlete’s foot is not typically serious, it can be persistent and lead to more severe complications if left untreated.

At QCity Podiatry, we specialise in diagnosing and treating athlete’s foot to ensure healthy, fungus-free feet.

What Causes Athlete’s Foot?

Athlete’s foot is caused by dermatophyte fungi, which feed on the keratin in the skin, nails, and hair. These fungi thrive in damp, warm conditions and spread quickly through direct contact or contaminated surfaces. Common causes and risk factors include:

• Walking barefoot in communal areas such as locker rooms, swimming pools, and public showers.
• Wearing damp socks and shoes that trap moisture and create a breeding ground for fungi.
• Poor foot hygiene, such as not drying feet properly or frequently wearing tight, non-breathable footwear.
• Having a weakened immune system due to diabetes, chronic illnesses, or certain medications.
• Sharing footwear, socks, or towels with an infected individual.
• Excessive sweating (hyperhidrosis) keeps feet moist and increases fungal growth.

Symptoms of Athlete’s Foot

Athlete’s foot can present in different ways, depending on the severity and location of the infection. Common symptoms include:

• Itching and burning sensation, especially between the toes.
• Red, scaly, or peeling skin on the feet.
• Cracked, blistered, or ulcerated skin can cause pain and discomfort.
• Foul odour, particularly when wearing closed-toe shoes.
• Thickened, discoloured toenails in cases where the infection spreads to the nails (onychomycosis).
• A dry, scaly rash on the sole, known as moccasin-type athlete’s foot.

Types of Athlete’s Foot

Athlete’s foot can appear in different forms, affecting various areas of the foot:

• Interdigital Athlete’s Foot: The most common type, affecting the skin between the toes, leading to peeling, cracking, and intense itching.
• Moccasin-Type Athlete’s Foot: Affects the soles of the feet, causing thick, scaly skin that may spread to the edges of the foot.
• Vesicular Athlete’s Foot Is characterised by fluid-filled blisters, often on the sole, that can become infected if scratched or popped.
• Ulcerative Athlete’s Foot: A severe form that leads to open sores and infections, requiring immediate medical attention.

Diagnosis of Athlete’s Foot

At QCity Podiatry, we diagnose athlete’s foot based on a visual examination and, if necessary, additional tests such as:

• Skin scraping and fungal culture: A small sample of the affected skin is examined under a microscope or sent for lab testing to confirm the presence of fungal infection.
• Wood’s lamp examination: A specialised ultraviolet light is used to detect fungal infections.
• Differential diagnosis: Ruling out other conditions such as eczema, psoriasis, or bacterial infections.

Effective Treatment Options for Athlete’s Foot

The treatment approach depends on the severity of the infection. Mild cases can often be treated at home, while more persistent or severe infections may require medication.

Over-the-counter (OTC) Antifungal Treatments

For mild cases, antifungal creams, powders, sprays, and lotions are effective in eliminating the infection. Common OTC treatments include:

• Clotrimazole, Miconazole, or Terbinafine: These antifungal agents stop fungal growth and relieve symptoms.
• Tolnaftate powders and sprays: Help keep feet dry and prevent reinfection.
• Antifungal wipes and soaps are helpful for daily foot hygiene to remove excess moisture and fungus.

Medications

For more stubborn or recurring infections, stronger antifungal treatments may be needed, including:

• Oral antifungal medications (e.g., terbinafine, itraconazole, fluconazole): These help eliminate deep-seated infections that do not respond to topical treatments.
• Topical antifungals: More potent creams and ointments may be recommended for severe cases.
• Corticosteroids: Sometimes prescribed to reduce severe inflammation and discomfort associated with athlete’s foot.

Home Remedies and Natural Treatments

While not as effective as medical treatments, some natural remedies may provide relief:

• Tea tree oil: Has antifungal properties and can be applied to the affected area (diluted with a carrier oil).
• Apple cider vinegar soaks may help create an acidic environment that inhibits fungal growth.
• Baking soda foot baths can help absorb excess moisture and reduce odour.

Preventing Athlete’s Foot

Preventative measures are key to avoiding recurrent infections. Follow these best practices to keep your feet fungus-free:

• Keep feet clean and dry. Wash feet daily with soap and water, and dry thoroughly, especially between the toes.
• Wear moisture-wicking socks. Change socks frequently, mainly if you sweat excessively.
• Choose breathable footwear. Wear shoes made of materials that allow air circulation, such as leather or mesh.
• Avoid walking barefoot in communal areas. Always wear sandals or shower shoes in locker rooms, gyms, and public pools.
• Use antifungal powders or sprays. Apply these to your feet and inside shoes to prevent fungal growth.
• Rotate footwear. Allow shoes to air out between uses to prevent moisture buildup.
• Do not share personal items. Avoid sharing socks, shoes, towels, and nail clippers with others.

When to See a Podiatrist

Professional medical care is recommended if the athlete’s foot does not improve with over-the-counter treatments or worsens. Seek podiatric evaluation if you experience:

• Persistent or severe itching, burning, or pain.
• Blisters or open sores that do not heal.
• Recurrent infections despite treatment.
• Signs of a secondary bacterial infection, such as pus, swelling, or fever.
• Involvement of the toenails, which may require specialised antifungal treatment.
• Complications due to diabetes or weakened immune function.
