Patients may be tempted to treat their rash with nonprescription drugs. However, if the condition is not properly diagnosed, such drugs could make the rash worse.

A dermatologist (skin specialist) can diagnosis athlete's foot by conducting a physical examination and studying skin scrapings from the foot under a microscope. When treated with potassium hydroxide, the scrapings show the presence of fungi.
