urinary tract infection
"I was prescribed Bactrim for a very painful UTI that I could not flush out naturally with water and cranberry. My UTI pain subsided after about 5 hours of the first dose of Bactrim which is great. However, the side effects are not so pleasant. I have had chills, mild diarrhea, vivid nightmares/dreams and extreme migraines. I am on day 3 of a 7 day prescription, but I am contemplating stopping after day 4 or 5 if the side effects continue. The side effects are still not as bad as the UTI pain!"
