TINEA CRURIS

(Jock Itch)

Basic information

Tinea cruris (jock itch) is a fungal infection of the skin in the groin. Tinea cruris is more likely to occur in men than in women.

Scaling red patches (often ring-shaped) on the skin of the groin, thighs, and buttocks.
Patches have well-defined edges.
Sometimes small, pus-filled blisters appear.
Itching of involved areas.
Pain (if the skin also becomes infected with bacteria).

Infection by fungi called dermatophytes. These germs tend to grow in the darkness, warmth, and moisture of the body's groin area.

Dry completely after bathing. Use clean towel.
Don't sit around in a wet bathing suit.
Wear loose fitting, cotton underwear.
Wear clean, dry athletic supporters and underwear for each workout.
Use nonprescription tolnaftate after bathing if you have had tinea cruris before. This powder can help prevent a recurrence.

Symptoms can be controlled in 2 to 4 weeks with treatment.

Your health care provider will do a physical exam of the affected area. Medical tests may include a microscopic exam of scraped-off scales.
Treatment usually involves a drug applied to the skin. Use it for the length of time prescribed, even if the rash goes away.
For home care, follow the steps listed in Preventive Measures.
If you also have an athlete's foot infection, treat both areas with equal care.

You may use nonprescription, topical antifungal drugs for treatment and prevention.
Other topical or oral (taken by mouth) antifungal drugs may be prescribed.

No limits.

No special diet.
