I have had pain in my bladder, right side and back and blood in my urine now since prior to March 07. the pain is intense, I feel as if I have a scouring pad in my bladder and someone is scrubbing it. The pain is so intense I get sick to my stomach. I have went through 8 bouts of antibiotics over a 3 month period with no change. I finally found a doctor to take me seriously but even at that he put me on more antibiotics for two weeks prior to sending me to the urologists. I am scheduled for a cystoscope and a bilateral pylogram on the 30th. I have had numerous cat scans and nothing shows up. Did your bladder cancer show on a catscan and did you have any of these symptoms?
