Affected areas may appear red, tan, or brown, with flaking, rippling, peeling, or cracking skin.
The acute infection begins with an area in the groin fold about a half-inch across, usually on both sides. The area may enlarge, and other sores may develop in no particular pattern. The rash appears as raised red plaques (platelike areas) and scaly patches with sharply defined borders that may blister and ooze.
If the rash advances, it usually advances down the inner thigh. The advancing edge is redder and more raised than areas that have been infected longer. The advancing edge is usually scaly, and very easily distinguished or well demarcated.
If the skin inflammation causes discomfort and itching, glucocorticoid steroids may be combined with the anti-fungal drug to help prevent further irritation due to the patient scratching the area. Apart from the quicker relief of symptoms, this also helps minimise the risk of secondary bacterial infection caused by the scratching. However, steroids may exacerbate the condition if used alone for fungal infections.
To cure the infection naturally, keep moist and warm areas of the body clean and dry. Change anything the fungus comes into contact with daily, like undergarments and towels. One can use talcum powder to help keep the area dry. Powders with menthol or zinc oxide like Gold Bond medicated powder, and creams containing 1% hydrocortisone should help soothe the itch if not treat the infection altogether. Avoid the transmission of the fungus to other parts of the body when drying. One may use anti-dandruff shampoos on the infected skin as many contain anti-fungal chemical compounds such as pyrithione zinc, selenium sulfide, and ketoconazole (Nizoral). Tea tree oil can also be used since it is a natural anti-fungal. Garlic is also known to have anti-fungal properties because it contains allicin.
In August of 2008 the University of Southern California Football team was struck with an outbreak of the fungus, to the point that 25% of the team was reporting discomfort. Blame has been placed on a new compression tight that was being worn beneath practice clothing.
