bacterial infection
"I was prescribed the 7-day, 3 times a day dose for BV. As to symptoms clearing/persisting, I wouldn't know because I didn't notice anything amiss to begin with (no noticeable smell or discharge). The GYN recommended Flagyl after my annual appointment possibly because I was developing BV.  



I don't know if it's the medicine, but I developed the worst sore throat I've had in years. Congestion interspersed with runny nose, sinus pressure, throat pain, sneezing, coughing, raw nose, the works. It feels like a mix between strep throat and a sinus infection. I feel like my head is in a vice.



The only other thing that's changed is darker urine than usual. I'm on my last pill and I started getting sick on day 4 of antibiotics."
