• Jock itch that is caused by tinea cruris is a fungal infection that affects the skin surface of your genitals, buttocks and inner thighs. Jock itch can causes an itchy, red, often round shaped rash in the are that is warm or moist areas of your body.

• Jock itch gets its name because it is common in patients who involved in sports and do sweat a lot such as an athlete. It also often occurs in patient who are overweight or obese, but anyone can get this problem. Although often it is uncomfortable and trouble some, jock itch usually does not come too serious, except possibly for patient with a weak immune systems.

• Keeping your groin area dry and clean and applying topical anti fungal creams like yourself usually are sufficient to treat jock itch. Jock itch can be treated using few treatments method. Home prevention can be done to reduce the risk of getting jock itch such as bathing more frequently, stay fry, be cool not hot, find the correct and comfortable out fits, do not share common items and wear a clean clothes.

• For the topical medicatios, the doctor might suggest to use or apply the cream average for at least 10 days, twice daily. It is good to stick with this plan before you stop the medication because it might re occur if it is not fully treated.
