A to Z: Tinea Cruris (Jock Itch)

May also be called: Jock Itch

Tinea cruris, commonly called jock itch, is a skin infection of the groin area caused by several types of fungi often found on the skin.

More to Know

The fungus tends to grow and spread in warm, damp areas of the body. It may be triggered by sweating in the groin area or friction caused by tight clothing.

Symptoms include a red rash with raised edges, and itching, redness, or flaking on the groin, upper inner thighs, or anus. Sometimes jock itch occurs at the same time as ringworm or athlete's foot, which are caused by the same fungus.

Jock itch can be spread from one person to another if they share clothing or towels. Jock itch occurs most often in teenage boys and adult men. It is more common in hot, humid weather and in people who play sports or sweat heavily. It's also more likely to affect people who are overweight or have diabetes mellitus.

Keep in Mind

Jock itch can be uncomfortable, but usually responds to treatment within a couple of weeks. An over-the-counter (OTC) antifungal cream, gel, or powder can be used to treat most cases. Sometimes, a severe infection or jock itch that doesn't respond to OTC treatments might require prescription medication.
