Athlete's foot

What is it?

Athlete's foot (tinea pedis) is caused by a fungus that grows on the skin. You do not have to be an athlete to get it. The fungus likes warm, damp places, like sweaty shoes, locker rooms, and pool decks. It can spread to the toenails and to other people.

Signs to watch for

• Itching, stinging, or burning, often between the toes
• Peeling, scaly, or white, soggy skin between the toes
• Cracks or splits in the skin
• Dry, scaly skin on the bottom or sides of the foot
• Small blisters in some cases

Care at home

• Wash your feet each day and dry them well, including between the toes
• Use an over-the-counter antifungal cream or spray as the label directs
• Keep using it for as long as the label says, even if the itch stops
• Wear clean, dry socks and change them if they get damp
• Let shoes dry out, and switch pairs when you can
• Wear shower shoes in public showers and pool areas

When to see a doctor

• It is not getting better after 2 weeks of home care
• You have cracks or open skin
• You have diabetes or poor circulation
• You see redness that spreads, swelling, pus, or you have a fever
• It keeps coming back

Common questions

Is athlete's foot contagious?

Yes. It can spread through shared floors, towels, and shoes. It can also spread to your toenails or hands if you scratch.

Why does it keep coming back?

The fungus can stay in shoes and socks, or in the toenails. Stopping treatment too soon can also let it return.
