My dermatologist gave me fluconazole to take once a week until it goes away. Has anybody ever tried this? I’m always afraid to take any new medications. My middle toe keeps getting an ingrown toenail and it’s so thick it’s hard to get out and it’s so painful. I keep stubbing it. Ugh My appointment with a podiatrist isn’t for a month.
