Athlete's Foot (Tinea Pedis)
What is athlete's foot?
Athlete's foot is a fungus infection that causes a scaly, cracked rash between the toes.
The rash may:
- itch and burn
- become raw and weepy when scratched
- spread to the instep
- cause the foot to have an odor.
What causes athlete's foot?
Athlete's foot is caused by a fungus that grows best on warm, damp skin. It occurs mainly in adolescents and adults. Prior to age 10 a red, scaly rash between the toes is usually not athlete's foot.
How long does it last?
How can I take care of my child?
Buy Lotrimin, Tinactin or Micatin cream at your drugstore. The cream works better than sprays or powders for children. You do not need a prescription for these medicines.
First, rinse the feet in plain water or water with a little white vinegar added. Dry the feet carefully, especially between the toes. Then apply the cream to the rash and well beyond its borders twice a day. Continue applying the antifungal cream for several weeks, or for at least 7 days after the rash seems to have cleared. Successful treatment often takes 3 or 4 weeks.
Keep the feet clean and dry. It helps to go barefoot or wear sandals or thongs as much as possible. Wear shoes that allow the feet to breathe. Wear cotton socks because the cotton absorbs sweat and keeps the feet dry. Change socks twice a day. Dry the feet thoroughly after baths and showers.
The feet often stop smelling bad when the athlete's foot improves. Rinsing the feet and changing socks twice a day are essential. If that doesn't work, rinse the feet in a basin of warm water containing 1 ounce of vinegar. If you can still smell your child coming, wash his tennis shoes in your washing machine with some soap and bleach.
Scratching infected feet will delay healing.
Athlete's foot is not easily passed from person to person but is thought to be spread by direct contact with contaminated surfaces such as locker room or bathroom floors. The fungus won't grow on dry, normal skin.
