Aptly named, jock itch is actually a fungal infection caused by the ringworm tinea cruris. Frequently suffered by active or athletic people, the fungus is highly contagious and has an affinity for dark, moist skin folds on the body such as the groin and anus. According to the Mayo Clinic, at home treatments are highly effective for most cases of jock itch.
Environment
Fungus multiplies in dark, moist environments. Wear loose cotton clothes as this allows fresh oxygen to reach the skin and dry out the groin. Underwear should be worn, but discard any tight or ill-fitting briefs as the friction can irritate the skin sores and cause weeping, or drainage. Shower after any exertion and keep the affected area clean and dry.
Dietary Considerations
Fungus requires high amounts of simple sugars to live. Complex carbohydrates, such as breads and pasta, are quickly broken down to sugar by metabolism and should be avoided. Any foods high in yeast content will also feed the fungus. Some suggest that increasing raw garlic and vegetables in the diet will counteract the fungus from the inside out.
Over-the-Counter Medications
Many preparations are commercialized as anti-fungal, but be sure to purchase medication with the right active ingredient. According to the Mayo Clinic, over-the-counter jock itch medications include terbinafine, naftifine, miconazole and clotrimazole. These preparations come in sprays, powders and creams and are commercially known by tradenames such as Lamisil and Lotrimin. Powders can be used to keep very moist areas dry, whereas sprays and creams will add to the moisture content of the area.
