bacterial infection
"Flagyl is the ONLY medication that gets me rid of my BV completely.   BV it's horrible and makes you feel disgusting. I feel better after the first day,  I usually take 2 daily for 5 to 7 days. MUST take with food and plenty of water throughout treatment. Chew the food then put pill in it, just before swallowing or wrap out in bread to avoid it touching your tongue. I hate the intravaginal kind, it's messy and makes my back and uterus hurt."
