trichomoniasis
"I found out a had trich from my  pap examination, the doctor immediately prescribed me metronidazole 500mg and to take all four pills at once. I'm not sure if it worked because I still feel the same way I felt before I took the pills. And I had no symptoms at all. So I wouldn't know how to rate the meds because I'm still hoping it just goes away by me just taking all four of those tablets. So can anyone tell me how long does trich last?"
