Jock itch is highly treatable with over-the-counter (OTC) medication. Although jock itch gets its name because it’s common in athletes, the condition is also experienced by people who sweat a lot or who are overweight. Although it can be uncomfortable, jock itch usually isn’t serious. Treatment may involve keeping the groin area clean and dry and applying topical antifungal medications to the affected skin. The fungus that causes jock itch is highly contagious. You can get it through close personal contact with an infected person or through skin-to-skin contact. The fungus can also be spread through contact with the unwashed clothing of an infected person. The infection often spreads from the feet to the groin because the fungus can travel on your hands or on a towel. You can also spread the infection by pulling up your underwear or pants if the waistband gets contaminated with the fungus from your feet.

People who are obese are at an increased risk for jock itch because of their moisture-trapping skinfolds. If you have diabetes, your risk of jock itch is increased in two ways: the excess sugar emitted in your sweat provides food for fungus, and your immune system is not as strong in general, making you more at risk for common skin infections. Rarely, doctors may take a small scraping of your skin to look at under a microscope. Tests are usually not necessary.

This infection often comes back more than once, especially if you also have fungal infections on your feet or toenails.

If you tend to get jock itch, you should continue to apply antifungal or drying powders after bathing to help prevent reoccurrence.
Prevention of Jock Itch
Practicing good hygiene is the best defense against jock itch. Regular hand-washing can greatly reduce your risk of getting this infection from someone else. It’s also important to keep your skin clean and dry, especially the area around your groin. You should also avoid tight-fitting clothing that can further increase your risk of jock itch. Wearing loose-fitting clothing, especially in hot and humid weather, can prevent sweat from creating the warm, moist environment in which the fungus thrives. Be sure to wash your workout clothes after each use and don’t share clothing, towels, or personal items with others. To avoid spreading athlete’s foot to your groin area, don’t use the same towel you use on your feet for your groin. Putting socks on before underwear can also help prevent you spreading nail and foot fungus (athlete’s feet) to the groin area. The AAD is a great resource for information about skin diseases and conditions. Although your primary care doctor can diagnose and treat jock itch, you can use this site to search for a dermatologist in your area if you prefer to see a specialist. Centers for Disease Control and Prevention (CDC) This component of the U.S. Department of Health and Human Services is a go-to source for up-to-date information, statistics, health-related travel advisories, and more. On the site, you can find detailed information about symptoms, diagnosis, and treatment for numerous forms of ringworm, including jock itch. Additional reporting by Joseph Bennington-Castro.
