I did one dose of the vaginal insert of metronidazole on a Sunday night, and woke up the next day and went pee and it burrrrrned. I skipped my dose on monday night becuae i went online and read that if you had those symptoms, to call your dr. I called them today and they told me to stop using the medication which i have.
