I just had a baby 5 months ago via c section. ever since then i have horrible vaginal burning with a copper oder sometimes. Have took flagyl twice a long with diflucan 100 mg bid for 1 week then 150mg 1 a week for 6 weeks and still am not better. Sex is painful now to for the burning and i can be sitting and all of the sudden get a strong burning sensation in my vagina. any ideas to what it could be that flagyl and monistat, and diflucan cannot fix. I have no STDs either.
