Bacterial Vaginitis
"Started Metronidazole 500mg (prescribed twice a day for 7 days) after testing positive for bacterial vaginitis. I took one dose at 11 am and the second dose at 11 pm. About an hour later I noticed my arms were turning a bit red and then I started itching on my back and then my chest. I looked in the mirror and I have these welts. They itch a lot and my throat is burning and I have a bit of a headache and my eyelids feel heavy. I took two Benadryl hoping the redness and itchiness doesn&#039;t get worse.  I will stop taking it and call my doctor. I hope I&#039;m not having an allergic reaction."
