urinary tract infection
"I was prescribed Macrobid in a third world country by an urgent care doctor.  So I'm not sure if or how it might differ from the US formulation.  I experienced absolutely no negative side effects.  Not even fatigue.  However, the pain and discomfort from the UTI returns right around the time I need to take my next pill (2x daily for 7 days).  After I take the pill, the pain goes away.  But after finishing all of my prescribed Macrobid, I still have some discomfort so I feel as though it did not clear up the infection."
