The signs of athlete's foot, singly or combined, include the following:
Athlete's foot may spread to the soles of the feet and to the toenails. It can be spread to other parts of the body by those who scratch the infection and then touch themselves elsewhere. The organisms causing athlete's foot may persist for long periods.
If you believe that you have a fungus infection that does not respond to proper foot hygiene and there is no improvement within two weeks, consult a podiatrist.
A podiatrist will determine if fungus is the cause of the problem. Topical or oral antifungal drugs are often prescribed. If the infection is caused by bacteria and not fungus, antibiotics that are effective against a broad spectrum of bacteria, such as penicillin, may be prescribed.
It is important to keep the feet dry by using foot powder in shoes and socks. The feet should be bathed frequently and all areas around the toes dried thoroughly. If someone in your family develops athlete’s foot, disinfect home showers and tubs after each use to discourage transmission of infection.
