I was dx with a Urine infection 3wks ago and after a run of Bactrim I am on macrodantin. The infection was Ecoli. This wk I have been sick with 102 fevers untl Fri. Went to ER thurs. and they forund a spot on liver and something suspicious on kidney. jdidn;t really address diaherrea. I cant eat and get bad diaherra iif I drink. Will Macrodantin cause this? I also khave diverticulosois.
