Jock Itch- tinea cruris

A fungal infection of the skin commonly found in the upper thighs, groin, buttocks or genital/anal regions of skin. Usually begins in the folds of the skin in active, athletic individuals due to frequent sweating. Caused by the same fungus that causes “athlete’s foot” and can be spread by clothing, towels or hands from scratching.

Signs and Symptoms:

  • Rash may appear circular or have small blisters

  • Over the counter topical creams, lotions and powders are available to relieve symptoms. Use as directed and it often can take 1-2 weeks of treatment to get desired results.
  • Prescription medications are available from a healthcare provider
  • Keep skin cool and dry
  • Avoid scratching that may lead to further infection of the skin or spreading


  • Avoid skin contact with infected person.
