Fungal infections on the thigh, commonly known as tinea cruris or jock itch, are typically treated with topical antifungal creams applied twice daily for 2–4 weeks as directed. Keeping the area clean, dry, and free from tight clothing helps prevent recurrence. In more severe or recurrent cases, oral antifungal medications may be prescribed. It is advisable to consult a dermatologist for an accurate diagnosis and appropriate treatment to ensure complete recovery.
