urinary tract infection
"I had a UTI finished an entire prescription of macrobid. I noticed as soon as I finished the meds my UTI symptoms came back - so it didn't work for m.  I then tried bactrim. The pain went away after 1.5 days of being on bactrim which was a huge relief but it is now day 4 and I am suffering from nausea, cold sweats, chills, insomnia and anxiety. It works for your UTI but the side effects are unbearable after a few days."
