Causes

Jock itch is caused by a fungus that lives on the outer layer of the skin. Heat and moisture contribute to the development of jock itch, so it is more common in the summer.

Self-Care

Jock itch usually clears up in 4 to 6 weeks with self-care.

• Wash the groin daily with a mild soap; rinse and dry thoroughly.
• Apply an over-the-counter antifungal cream (such as Lotrimin or Micatin) to the rash and surrounding area 3 to 4 times a day. Because the fungus can continue to live under the skin even after your symptoms disappear, you should continue to use the antifungal cream for 1 week after the rash clears.
• Apply a body powder to absorb moisture and reduce friction.
• Avoid sharing towels to prevent infecting others with the fungus.
