Jock Itch

What is Jock Itch?

Jock itch, also known as tinea cruris, is an infection caused by a common fungus. Since the areas it affects usually stay dark and moist, it is a welcoming habitat for fungus. This condition usually affects the skin on the genitals, buttocks, and inner thighs.

The condition is named for the group of the population that suffers from it most frequently. Jocks sweat a lot, and so do athletes. However, the condition does occur frequently in people who are overweight or exercise frequently.

Even though the condition is uncomfortable and irritating, it is usually not serious. However, those who suffer from it are in a hurry to find relief from the symptoms.

At risk

  • Men
  • Males who fall into the category of teens or young adults
  • People who wear tight fitting underwear
  • People who are overweight
  • People who sweat heavily
  • People with a weakened immune system
  • People who have diabetes

What are the Symptoms of Jock Itch?

Jock itch begins with an area of the skin that is red in color. Usually this starts out in the crease of the groin and develops outward into a half-moon shape on the upper thigh. The edge of the rash starting in the groin is usually made up of a consistent line of small raised blisters.

While it may start out as a red discoloration that mimics chaffing, the rash will begin to itch or burn over time. The skin can also become flaky, or even scaly after being exposed to rubbing clothing over time.

While having jock itch may be concerning, medical treatment is usually not required if it responds to over-the-counter medications. It is recommended that you see your doctor if your condition does not respond to over-the-counter treatments after two weeks.

How is Jock Itch Treated?

A mild case of jock itch usually responds well to over-the-counter anti-fungal creams, ointments, lotions, powders, or spray. Usually, once you begin using these regularly, the rash will clear up in one to two weeks.

For those who are suffering from athletes foot, as well as jock itch, treating them both at the same time will reduce the chance of recurrence in both cases.
