urinary tract infection
"Tested positive for UTI and was put on nitrofurantoin, 100mg 2x per day for 7 days.  No problems the first day, evening of second day I started with a frequent dry cough (not quite hacking, but close).  Only able to sleep 1-2 hours per night and coughing got worse each day.  Called clinic on 5th day and changed to Bactrim for 3 days.  No burning, some pressure and frequent urge to urinate.

Going to doctor for regular checkup today and will discuss this, but will not take this medicine again."
