Jock Itch

This irritating problem, known to doctors as tinea cruris, is a fungal infection that occurs in the groin area. A close relative of ringworm and athlete's foot, it is far more common in men than in women. It may be caused by any of several different organisms called dermatophytes that live parasitically on skin.

Jock itch typically appears as a reddish, moist, itching area that extends from the inner thigh up to its intersection with the scrotum. The genitals themselves may be minimally affected, if it all. It is not considered a serious infection, but it can be persistent, and recurrences are common. Once the skin becomes susceptible, the organism seems to be able to take advantage of any opportunity. Such chances occur more frequently during the summer months.

Tight clothing can make the situation worse, as friction, lack of air, and sweating tend to favor fungal growth. The itching can set the stage for other problems, such as bacterial infection and candidasis, to complicate the situation. In addition, reactions to some of the ingredients in the medications used to treat jock itch can sometimes cause local inflammatory skin reactions.

Contact dermatitis, or skin eruptions due to sensitivity to something that comes into contact with the skin, may sometimes be mistaken for jock itch, as can psoriasis.

General Recommendations

Wear clean cotton underwear. If possible, wearing loose cotton pants with no underwear for several or more hours per day is recommended, especially when the rash is at its worst.

Excessive moisture tends to worsen the rash. Try not to wear thick, warm clothing that would cause excessive sweating. After showering or bathing, make certain that the area is thoroughly patted dry and then wash the towel in hot water, with chlorine bleach added if possible, to avoid reinfecting yourself.

Prevention

Practice meticulous hygiene. Keep the groin area clean, cool, and dry.

Don't share towels, washcloths, or anything else that might harbor infectious fungi.
