How do you get rid of jock itch fast?

Apply an over-the-counter antifungal cream twice daily, keep the area clean and completely dry, wear loose breathable underwear, and continue treatment for the full recommended course even after the rash clears. Treating any athlete's foot at the same time prevents the fungus from coming back.

No. Jock itch is a fungal skin infection, not a sexually transmitted disease, although it can occasionally be passed through close skin contact. It's most often spread from a person's own athlete's foot or from shared towels and clothing.

Why does my jock itch keep coming back?

Recurrences are common if athlete's foot isn't treated at the same time, if the area stays warm and moist, or if you stop treatment too early. Keeping dry, finishing the full antifungal course, and treating your feet help prevent it returning.

Jock Itch

Also known as: Tinea cruris, Groin fungal infection, Ringworm of the groin

Jock itch (tinea cruris) is a fungal infection of the skin in the groin, inner thighs, and buttocks. Caused by the same dermatophyte fungi as athlete's foot and ringworm, it produces an itchy, red, often ring-shaped rash that thrives in warm, moist areas. It is more common in men and athletes, is mildly contagious, and usually clears with antifungal treatment and keeping the area dry.
