bacterial infection
"I've taken Flagyl several times for severe sinus infections. It did help considering the side effects. Currently I began Flagyl 5 days ago 3 x a day for C-Diff ...The C-Diff symptoms were bad enough but the side effects this time are horrible. Severe nausea ,insomnia, itchy hot skin and a general feeling of sickness. I still have 5 more days to go and want to discontinue the medicines. "
