We can try! Toenail fungus is very common, and unfortunately very difficult to cure 100%. We can test the nail to see if it is a callused or traumatized nail or if it is indeed fungus, and from there you have several options: topical or oral antifungal medications, laser nail treatment, or removal of the nail in severe cases.
