Jock itch is a fungal skin infection that causes an itchy rash in warm, moist areas of the body. The rash often affects the groin and inner thighs and may be shaped like a ring. It is common in athletes and in people who sweat a lot. This condition can range from mild to serious. It usually clears up in 1 to 3 weeks with antifungal creams and self-care.
