it might be advisable to get your Doc. to order a full renal blood work .not just for infection but for kidney disease. i have 5 fused disc and all ways thought that my pain was from my back .
well guess what??? ugh kidney disease no infection no inflammation on spine .took 5 yrs too find the cause of most of my pain
Oooops I see you had a CT Scan.
My only other thought is that sometimes gravel can cause what you describe and not show up on tests.
Feel so bad for you ... I've had serious issues with a 2.0 mm stone but mine did show up on an CT Scan but not an X Ray, but was calcium oxalate -- go figure!

Did the Dr put you on a full course of antibiotics for your "kidney infection" or take you off when the culture was negative? Many times stones can cause UTI's that don't show up positive.
Did they do a CT Scan?
