Metronidazole
"The medicine has done nothing for me but been a tease.  I was so excited about the being free the indescribable itch. I have no other symptoms but the itch is annoying.  Day 4,the itch lingers.  I had not had sex, used toys and  always been clean using the bathroom etc.  Where did this come from? Thank God I am not in a relationship because it would--it would have been over! Bottom-line, tonight I took two 500mg to see if a 1000 strength would give me a little relief.  This is sickening!  I don't understand how some have gone through this before and even for years and months.  I am going crazy after two weeks of thinking I had a yeast infection to learn I am fighting BV.  I have Dr. apt at 10am in the morning--need to try another drug!"
