Q: What is athlete’s foot? A: Athlete’s foot is caused by a fungal infection of the skin and usually appears in between the toes or in the arch area of the foot. Common signs and symptoms are redness, itchiness, and burning. Walking in wet public areas and wearing damp, dirty socks and shoes are common ways to get athlete’s foot. There are several over-the-counter and prescription medications that can treat the problem, though creams, ointments, or gels tend to be more effective than powders or sprays are. To truly eliminate the fungus, you should continue with the medication for an additional two weeks after the symptoms have disappeared.
