How to kill fungus
Purchase over-the-counter anti-fungal cream and ointments.
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. Wash your hands before and after using the treatment.
