A toenail that is infected by a fungus usually turns white or yellow. As the fungus spreads, the nail turns a darker colour and gets thicker, and its edges start to turn ragged and crumble. A bad infection can cause toe pain, and the nail may pull away from the toe.
Toenails that are exposed to moisture and warmth a lot are more likely to get infected by a fungus. This can happen from wearing sweaty shoes often and from walking barefoot on shower floors.
It is hard to treat toenail fungus, and the infection can return after it has cleared up. But medicines can sometimes get rid of toenail fungus for good. If the infection is very bad, or if it causes a lot of pain, you may need to have the nail removed.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
