What Causes Jock Itch, and How Is It Cured?

Jock itch, a fungal infection of the skin on the groin, is treated by keeping the area dry and applying topical antifungal medications, according to MedlinePlus. If over-the-counter medications do not work or the condition recurs, a doctor may prescribe stronger medication or antibiotics for secondary infections.

Jock itch is a form of ringworm, according to WebMD. The fungus that causes it grows best in warm, moist areas of the body, including the groin. Symptoms include itching and pain, along with rash in the groin, buttocks, inner thighs or skin folds. Large bumps that look like blisters sometimes develop along the outer edge of the rash, and the center turns a brown or red.

Jock itch is more common among men, but it sometimes affects women. It often affects athletes due to increased perspiration from intense workouts. Improperly fitting clothes cause chaffing, increasing the chances of an infection, according to Mayo Clinic. Washing clothing, especially underwear and athletic supporters, after each use decreases the chance of developing the fungal infection.

Over-the-counter treatments for jock itch usually contain antifungal medications, including miconazole, clotrimazole, terbinafine or tolnaftate, reports MedlinePlus. The condition usually clears quickly with these medications, but individuals with infections that last more than two weeks should see a physician.
