Hi all. I started with s/s of UTI last week and immediately requested a UA which came back positive. A nurse from the office called me in a prescription for Bactrim (which i have successfully taken in the past). It's been 5 full days on the Bactrim and i am still having burning, urgency and now right, lower abdominal discomfort and backache that radiates to my shoulder blades at times.
Should i call and get another antibiotic or should i wait out the course of this treatment as it was effective in the past?
Could this signal a more serious condition like kidney infection?
