Jock itch, or tinea cruris, is a fungal infection that affects of the skin of the groin, buttocks and inner thighs. The infection, also known as ringworm, is common among athletes. However, you don't have to be a "jock" to get jock itch; anyone can develop this skin condition. Although jock itch is bothersome, it is rarely serious.
SYMPTOMS
The fungus that causes jock itch likes thrives in the warm, moist parts of the genital area. A patchy red rash develops; the affected skin itches and may crack or peel. The rash has a distinct red edge.
TREATMENT
Over-the-counter antifungal sprays or creams are available without a prescription. The active ingredients in these products include miconazole, clotrimazole and terbinafine. Use these products as directed. Although jock itch is often intensely itchy, try not to scratch. Cool compresses may help reduce itching. Keep the area clean and dry. Wear loose clothing to reduce skin irritation. If the infection doesn't clear after two weeks of treatment, call your health care provider. You may need a prescription-strength topical medication or an oral antifungal medication.
PREVENTION
You can help prevent jock itch by keeping the area clean and dry. Take a bath or shower daily and dry your genital area and inner thighs thoroughly. If you have an active infection, use a separate towel to dry the affected area to prevent spreading the fungus to other areas of your body. Make sure your gym clothes or sports uniform fit well; skin irritation promotes the development of jock itch. Activewear made with wicking fabrics helps keep your skin dry. Wash your workout or sports clothes, including your athletic supporter, after each use. Don't share towels or clothes with other people; jock itch is contagious. Change your underwear at least once a day, and change out of damp clothes after your activity concludes.
WHEN TO SEEK CARE
Call your health care provider if you have a case of jock itch that doesn't respond to over-the-counter treatment. Jock itch tends to be stubborn in people with a weakened immune system or diabetes. See your doctor if you have recurrent episodes of jock itch to be sure you don't have an underlying medical problem. Call your doctor right away if the affected area swells, feels hot, exudes pus, suddenly spreads or you develop a fever. These may be signs of a secondary bacterial infection.
