Hi, I Recently Took Flagyl For BV But By Day

Hi, I recently took Flagyl for BV but by day 4 I started to develop confusion, a red rash, burning in my legs and feet and hands, and shakiness. My ears are ringing constantly and my knees and ankles are swelling and I stopped taking the Flagyl on Saturday. It's now Wednesday and I seem to still be getting worse. I feel like I have a terrible sunburn and can barely get out of bed. My knees are swelling and I have goosebumps even when I'm not cold. And my skin is very very dry and almost sunken in in some places. What's wrong with me and when will this stop?
