Fungal Infections

Fungal infections on the skin of the feet are referred to as tinea pedis or commonly, Athlete's Foot. When fungus spreads to the nail, this is called onychomycosis.

Risks for Fungal Infection

Nails that are exposed to moisture and warmth a lot are more likely to get infected by a fungus. This can happen from wearing sweaty shoes often and from walking barefoot on shower floors. Or it can happen if you share personal things, such as towels and nail clippers. Genetics also play a role in the risk of developing a fungal infection; if mom or dad developed fungal infections, you are at a higher risk of developing the same infection.


A nail that is infected by a fungus usually turns white or yellow. As the fungus spreads, the nail turns a darker color and gets thicker. And the nail edges start to turn ragged and crumble. A bad infection can cause pain, and the nail may pull away from the toe or finger.

It's hard to treat nail fungus. And the infection can return after it has cleared up. But medicines can sometimes get rid of nail fungus for good. If the infection is very bad, or if it causes a lot of pain, you may need to have the nail removed.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

Tinea Pedis

Athlete's foot is an itchy rash on the foot caused by an infection with a fungus. You can get it by going barefoot in wet public areas, such as swimming pools or locker rooms. Many times there is no clear reason why you get athlete's foot. You can easily treat athlete's foot by putting medicine on your feet for 1 to 6 weeks. In some cases, a doctor may prescribe pills to kill the fungus.

Tinea Pedis frequently presents with a dry, scaling rash on the bottom of the feet.
