Summarize this article:

If you have an infection of the skin or nails that affects only a small area and does not cause much irritation, you may consider trying over-the-counter treatments before seeing your doctor. Buy topical antifungal treatments at your local pharmacy or drugstore. Keep in mind that these treatments often work better on skin than nails. Make sure your hands are as clean as possible before touching the affected area. Run warm water over hands and clean them with antibacterial soap. This can help prevent you from irritating your skin even further. Washing your hands after you touch the affected area can help prevent the infection spreading elsewhere. Most topical antifungal treatments need to be applied directly to the infected area. Refer to the instructions on the label of your treatment to ensure that you use it correctly. In most cases, place a small amount of cream or ointment on your fingers and rub it directly onto the infected area. Do not use topical treatments more than the product's label directs you to, unless your doctor has told you otherwise. You want to make sure the treatment absorbs into your skin or nail rather than any fabric around your foot. Avoid taking a bath or shower immediately after applying the treatment. If the cream or ointment you're using gives you a rash or seems to make your condition worse, stop using it immediately. Contact your doctor if the side effects don't go away in a few days. If your symptoms don't improve within 2 weeks, seek medical attention. Seek medical attention immediately if your infection spreads or starts to cause greater irritation. In most cases, your doctor will prescribe stronger antifungal medication. Use this prescription medication only as directed.

Summary:
Purchase over-the-counter anti-fungal cream and ointments. Wash your hands before and after using the treatment. Follow the instructions on the treatment's label. Let the cream or ointment dry before putting on socks or shoes. Stop using the treatment if you have adverse side effects. See your doctor if over-the-counter remedies don't help.
