- Jock itch, medically called tinea curis, is caused by a fungus. It commonly causes a roundish rash on the thighs, genital area, anus and buttocks. The rash causes both itching and redness and may also cause a burning sensation. When it's present in the genital area, flaking, peeling and cracking may also be evident.
- Dermatophytes are the fungi that lead to jock itch. They live on the body under normal circumstances and usually do not cause trouble. However, when certain areas are allowed to stay moist and warm, the fungi are able to grow and cause the fungal infection that is jock itch. Fortunately, jock itch is not highly contagious, except through very close contact. It is best to avoid sharing towels and clothing with someone who has the infection, as it can be spread in this manner. Likewise, you can contract it from having sex with someone with an active jock itch infection.
- Since the fungi that cause jock itch grow well in damp, warm, humid settings, it is best to avoid wearing tight underwear and athletic supporters, especially those that aren't washed after every wear. If you tend to sweat a lot, changing your clothing more frequently during the day may help. Likewise, an extra shower on hot summer days may help prevent infection. Keep in mind that is a very important to dry your skin well after a shower, as damp skin will only help the fungi to grow.
- Certain people are more prone to developing jock itch than others. For example, people with diabetes or AIDS may be more likely to develop the condition because of impaired immune system function. Also, people with atopic dermatitis, which is a skin condition that causes itching and inflammation, are more likely to develop jock itch. With these types of conditions, the body's normal protections against fungi are weakened.
- Generally, jock itch is treatable with over-the-counter anti-fungal medications, such as terbinafine (Lamisil AT) and miconazole (Monistat-Derm). However, if you have jock itch that hangs around after two weeks of treatment with over-the-counter medications, it's time to see a doctor for a prescription remedy. Your doctor may prescribe things such as econazole (Spectazole) for topical treatment or fluconazole (Diflucan) for oral medication treatment. Additionally, you should seek medical assistance if you develop fever, extreme redness or swelling as a result of your jock itch.
