I went to min clinic and tested positive for uti put me on bactruim. 3 days later still having blood in urine pelvic pressure and back pain under ribs. Went to my family doctor and he put me on cipro sent my urine to lab. Came back not uti kidney infection but still signs of infection. I just finished my cipro and still having issues. I made an appointment to see my gyno. What could be causing this?
