Jock itch (tinea cruris) is a fungal infection that affects the skin of your genitals, inner thighs and buttocks. Jock itch causes an itchy, red, often ring-shaped rash in these warm, moist areas of your body. Jock itch gets its name because it is common in people who sweat a lot, as do athletes. It also is more likely to occur in people who are overweight. Although often uncomfortable and bothersome, jock itch usually isnt serious. Keeping your groin area clean and dry and applying topical antifungal medications usually are sufficient to treat jock itch. Jock itch usually begins with a reddened area of skin that spreads out from the crease in the groin in a half-moon shape onto the upper thigh. The border of the rash may consist of a line of small, raised blisters. The rash often itches or burns, and the skin may be flaky or scaly. When to see a doctor See your doctor if you have a rash on your skin that doesnt improve within two weeks or if you treat it with over-the-counter medications and it returns within a few weeks. You may need prescription medication. Jock itch is caused by a type of fungus that can be spread from person to person or from shared use of contaminated towels or clothing. Jock itch is often caused by the same fungus that results in athletes foot. Its common for the infection to spread from the feet to the groin, as the fungus can travel on your hands or on a towel. Risk factors The organisms that cause jock itch thrive in damp, close environments. Youre at greater risk of jock itch if you: •Are a man •Wear tight underwear •Are overweight •Sweat heavily •Have a weakened immune system •Have other skin conditions
