What is jock itch?

Jock itch is a fungus that causes the pink, scaly, extremely itchy rash on the inner thighs, groin, and scrotum. (Note: The rash is not on the penis.) Jock itch is much more common in men than women. Jock itch is also called ringworm of the crotch or tinea cruris.

What is the cause?

Jock itch is caused by a fungus, often the same one that causes athlete's foot. Sometimes it is transferred by a towel used to dry the feet and then the groin area.

How long does it last?

With appropriate treatment, the symptoms are better in 2 or 3 days and the rash is cured in 3 to 4 weeks.

How can I take care of my child?

• Antifungal medicine

  Buy Tinactin, Micatin, or Lotrimin powder or spray (nonprescription) at your drugstore. Twice a day put the powder or spray on the rash and at least 1 inch beyond the borders of the rash. Make sure you get the medicine in all the creases.

  Continue using the medicine for several weeks, or for at least 7 days after the rash seems to have gone away.

• Dryness

  Jock itch will heal much more quickly if the groin area is kept dry. Your child should wear loosely fitting cotton shorts. Shorts and athletic supporters should be washed frequently. The rash area should be carefully cleansed once a day with plain water and carefully dried. Do not put soap on the rash.

• Scratching

  Scratching will delay the cure, so encourage your child not to scratch the area.

• Contagiousness

  Jock itch is not very contagious. The fungus won't grow on dry, normal skin. Your child may continue to take gym and play sports.

When should I call my child's health care provider?

Call during office hours if:

• There is no improvement in 1 week.
• The rash is not completely cured in 1 month.
• You have other questions or concerns.
