bacterial vaginitis
"I took 500mg Metronidazole 2x/day for a week when I tested positive for BV.  I felt tired and under the weather, but my symptoms weren't extreme.  However, I had little to no symptoms of BV before the treatment, but now, 2 weeks after taking these antibiotics, I am experiencing itching, dryness, discharge and odor.  I think that taking this antibiotic made things worse in the long run."
