I just finished a two day/4 pills each day of Tinidazole. My symptoms have gone from a 10 yesterday to an 8 today. Should I call doctor for another round or is this medicine still working?? Long holiday weekend and I'm not sure what to do. Should I call and ask for another round of this medicine? I don't think I can handle any more of this awful burning... it's almost debilitating. Thanks so much!
