Athlete's foot is a skin disease caused by a fungus, usually found between the toes. This fungus commonly attacks the feet because shoes create warm, dark, and humid environments which encourage the growth of fungus.
Warm and damp area such as swimming pools, showers, and lockers room often host the breeding ground for fungi. Because this infection is very common in athletes who used these types of facilities frequently, the name "athlete's foot" was derived.
Inflammation, blisters, dry skin and itching are all signs of athlete's foot. Athlete's foot often spreads to the toenails, as well as other parts of the body. Itching and burning may increase as the infection spreads.
If left untreated, athlete's foot can blister and cause a break in skin leaving you susceptible to a bacterial infection. In its early stages, the redness and itching can be treated with topical creams and liquids. In more severe cases, oral medication is required. In the most severe cases nail removal, followed by oral and topical medication more often than not will cure this problem.
