Jock itch, which is also referred to as tinea cruris, is a fungal infection that can affect the skin of the groin, buttocks or upper thighs. The fungus---called dermatophytes---is highly contagious and can be spread by sharing contaminated clothing or towels. Jock itch is a relatively common condition, especially in athletes and people who sweat frequently. If you develop any symptoms of jock itch, your doctor may prescribe an antifungal medication to resolve this condition.
Itching
As the name implies, the most common symptom is itching. The skin around your genitals, buttocks, anus or upper thighs may become red or irritated---especially if you scratch frequently. You may find that wearing tight clothing, such as your athletic uniform or underwear, may worsen itching symptoms. Scratching may increase your risk of developing an additional skin infection. You may find that application of over-the-counter drying powders or antifungal ointments may help alleviate the itchy symptoms. If they persist for longer than two weeks, speak with your doctor for additional medical care as this symptom may be indicative of another type of genital infection.
Burning
Certain people with jock itch may develop a mild to moderate burning sensation over the effected areas of skin. It may be helpful to clean and dry the effected area several times a day to alleviate this symptom. Speak with your doctor if this burning sensation persists, as it may also be indicative of a sexually transmitted disease.
Dryness
If you develop jock itch, you may notice that the skin of your genitals, anus, buttocks or upper thighs becomes excessively dry. Jock itch may cause skin lesions to develop in these areas, which may appear red, flaky, cracked or scaly. These skin lesions may develop into fluid-filled blisters that can burst---especially if you frequently scratch the affected area.
