Jock itch (tinea cruris) is a common fungal rash in the groin, inner thighs, or buttocks. It feels itchy, often looks red or scaly, and gets worse when you sweat. The good news: most cases clear with simple home care and an over-the-counter antifungal. This page gives clear steps to stop the itch, avoid repeats, and know when to see a doctor.
If you notice redness, flaking, or constant itching, start with these practical steps today:
Small tip: athlete’s foot can spread to the groin, so check your feet. Treat both areas if needed to prevent reinfection.

Prescription options include oral antifungals (like fluconazole or oral terbinafine) for severe or stubborn cases. Avoid steroid creams unless a doctor prescribes them—steroids can hide fungal infections and make them worse.
To reduce future episodes: change out of sweaty clothes right after exercise, use talc-free antifungal powder if you’re prone to sweating, and keep a spare set of clean underwear daily. If gym mats or locker-room floors are a risk where you train, wear flip-flops and shower right away.
Jock itch is annoying but usually easy to fix. Start drying and treating the area promptly, finish the full course of antifungal treatment, and follow simple hygiene steps to keep it from coming back. If it’s stubborn or spreads, get medical help so you can stop it for good.
