Fungal Infections (Toenails & Athlete’s Foot)
Fungal infections of the feet and toenails—known as tinea pedis (athlete’s foot) and onychomycosis—are common conditions that can cause itching, peeling, and thickened, discolored nails. They are often picked up in warm, moist environments like locker rooms or from shared footwear.
At The Medical Group of New Jersey, our podiatrists diagnose and treat fungal infections early to prevent spreading and recurrence. We combine topical or oral antifungal medications, hygiene education, and preventive care for long-term skin and nail health.
Symptom Onset & Initial Evaluation
Symptoms of fungal infections vary depending on whether the skin or nails are affected.
Athlete’s Foot (Tinea Pedis):
- Itching, redness, or scaling between toes
- Peeling or cracked skin on the soles
- Burning sensation after activity
Toenail Fungus (Onychomycosis):
- Yellow, thickened, or brittle nails
- Debris buildup under the nail
- Separation of the nail from the nail bed
During your visit, your podiatrist will examine the affected area, review hygiene habits, and identify any risk factors such as diabetes, excessive sweating, or frequent shoe sharing.
Diagnosis
Diagnosis is typically clinical, but may be confirmed with:
- Microscopic exam (KOH prep): Identifies fungal elements in nail or skin scrapings
- Culture testing: Determines the specific fungal species
- Nail biopsy: Rarely needed for resistant or atypical infections
Accurate diagnosis helps your podiatrist at The Medical Group of New Jersey select the most effective antifungal therapy for your condition.
Treatment
Treatment depends on the severity and location of the infection.
Topical Therapy
- Antifungal creams, sprays, or powders for mild skin infections
- Medicated nail lacquers for early toenail fungus
Oral Medication
- Terbinafine or itraconazole for moderate to severe toenail infections
- Blood tests may be required to monitor liver function during treatment
Adjunctive & Preventive Care
- Keep feet clean and dry
- Change socks and shoes daily
- Use antifungal powder or spray to prevent reinfection
Our podiatrists often combine topical and oral therapies with preventive guidance to achieve lasting results.
Ongoing Management & Prevention
Long-term management focuses on preventing recurrence:
- Avoid walking barefoot in communal areas
- Wear moisture-wicking socks and breathable footwear
- Disinfect nail tools and avoid shared pedicure instruments
- Schedule periodic nail and skin checks, especially if diabetic or immunocompromised
With early diagnosis and ongoing care from The Medical Group of New Jersey, most fungal infections clear completely and do not return.
