Athlete's foot is the most common type of fungal infection. Also called tinea pedis, it develops in the moist areas between toes and other parts of the foot. Athlete's foot usually causes itching, stinging and burning. It can also cause cracking and peeling skin, excessive skin dryness on the feet, and toenails that are thick, crumbly, ragged, discolored or pulling away from the nail bed.
Athlete's foot is contagious and can often be treated with over-the-counter antifungal medications.
