About 3 months ago I began having a pain on the left side of my mid to lower back, more towards the side of my back than the center where I experience back pain from herniated discs. It didn't abate at all, so trying to see if it might be a UTI, I urinated in a cup to check the appearance. It was brown and somewhat cloudy, so I went to the drugstore and got two different UTI home-test kits. Both were negative, so I called a urologist and made an appointment. There the dipstick turned up lots of blood in my urine, so I was scheduled for a CT scan. It was negative except for some calcium deposits in my pelvic area and a cyst on my left kidney. I was then scheduled for a cystoscopy which revealed no problems with my bladder. Urine was collected from my bladder for cytology. That was 9 days ago and I have not heard anything. However, my urine is getting darker and cloudier. I bought some UTI strips that reveal +++ for blood, a slight rise in protein and a high Specific Gravity. Yesterday, my urine was really horrible looking, so I saved a couple of different samples and noticed after about 1/2 hr. that about 1/4 of the volume was a residue that settled on the bottom. After draining off the top part, I noticed small blood clots, blood residue and many small (sand grain sized) black specks. Anybody know what this could be or has had the same symptoms? I don't know what to do now. Not real happy with the lack of concern from the urologist. Many thanks, Terri in Florida
