I went to an urgent care 7 days ago and had a urine test done and the urinalysis came back with glucose, ketones, blood, nitrates, protein and high leukocytes in my urine so they started treating me for a UTI with Bactrim, by Sunday I was not feeling any better I called them about the culture and it came back negative for an infection, I have had pelvic pain, lower back pain since, they even tried changing the antibiotic and still no change, I am now having black specks in my urine and I have burning and pain after I go to the bathroom, I had a ct scan done and was told it was normal, do you have and suggestions for me?
