Hello,I have kidney stones,apparently four altogether but have not really had any problems with them,however last week I had quite a noticeable bloody urine which by the next morning had gone.The next day I took a sample to the doctors who sent it off for analysis to see if there was any infection.I had a call the next day from the doctor stating that there was no infection but still a little bit of blood.To be honest I told her that I really didn't want to be re referred back to the urologist.The doctor is now sending me for a CT scan just to rule out bladder or kidney cancer.Since then I have been a nervous wreck and I'm really scared.
