A doctor should be seen to properly diagnose athlete’s foot. There are several over-the-counter creams, sprays, and powders available to treat athlete’s foot. Medications of any kind should not be used without first consulting a healthcare professional or doctor. A doctor can also prescribe topical or oral medications to treat severe cases.
