Athlete’s foot is a chronic infection caused by various types of fungus. It is often spread in places where people go barefoot such as public showers or swimming pools. The condition ranges from mild scaling and itching to painful inflammation and blisters. It usually starts between the toes or on the arch and may spread to the bottom and sides of the foot.

Depending on the type of infection you have, various kinds of medication may be used in treating your fungal problem. Successful treatment usually involves a combination of medication and self-care.
