I have not had BV since, however, earlier this month I got another case and
on 2/5/14 I was put on metronidazole
again. The 7 day course ended on 2/12/14 and exactly 5 days later, I broke out in that same case of hives. My scalp, neck, jaw line, and hip bones are covered in painful hives. I am back on a prednisone and cross my fingers it will help faster than last time which took 4 days to clear.
