this is my third round in three months of flagyl, i asked the dr to put me on it. this time it cleared up my joint pain and my diaherra is like I know when it is goung to happen but its not stopping is it because I am taking tylonal cold, im confused. Usually my diaherra just happens and i cant control when i go so i shouldnt be complaining, and im nausated. not all the time. any input???
