Urinary Tract Infection
"Was prescribed 3 days of trimethoprim for a UTI and they didn&#039;t touch it. I&#039;m now on day 6 of a 7 day course of nitrafurantoin and I have had terrible diarrhea and stomach cramps. My wee has also turned a bright yellow which I&#039;m concerned about since I thought it only turned dark yellow or brown on these tablets. Anyway, my UTI symptoms don&#039;t seem to have gotten any better."
