Finished 2000mg/amox for sinus infec. 3 days later started what i thought was a yeast infection; 2 doses of diflucan-still have some sour-musky discha?

Other infection?: Try an over-the-counter medication like Monistat vaginal cream for 7 days. If no effect, see your doctor about the possibility of something other than yeast causing infection.

Wait, and . . .: It can take anywhere from 3 to 7 days for Diflucan (fluconazole) to make you feel better. While you're waiting, you could use some over-the-counter cream like Gyne-Lotrimin to apply on the outside, and that may be comforting. To help rebalance your vaginal flora, try Luvena brand vaginal inserts and vaginal probiotic supplements. See a GYN if you're not back to normal in a couple weeks.
