urinary tract infection
"I found out I had a UTI a week after I had my annual physical examination. I did not get my prescription until a week later so I would assume I had the UTI for two weeks to a month. Doc prescribed me to take two 500mg daily. The side affects suck. Night one I did not sleep. I took a 3 hour nap and was up for 16 hours. Day two's morning dose had me nauseous. I just took my night dose so hopefully the side effects won't be bad. My UTI symptoms went away within my first dosage (slight pressure, cloudy urine, sensitivity)"
