Is the toenail fungus currently being treated?

I have been treating my toenail fungus for five years. Last time, it seemed to have improved externally, so I stopped post-treatment for a few months, but it recurred, and I am suffering now. Seeing the recurrence, my doctor told me that even after the fungus appears to be gone, treatment should continue for at least six months to achieve full recovery. I am particularly unable to take medication due to kidney problems (I cannot take antifungal drugs). Only through thorough post-treatment can I truly be cured of the fungus. This time, I am determined to walk the path to complete recovery.
