The recipe is...: Don't assume you have a fungus (even if you are a fun guy). Many skin problems can look fungal, and may even have an element of fungus in them, but it's important to get an accurate diagnosis before treatment. You can try using an otc anti-fungal medication. If it works, you need to treat it for 30 days, since fungal spores live for 30 days, even if it goes away in a couple of days.
