A couple weeks ago It felt like I could not empty my bladder, going all the time, and a burning constant urethra at the tip end of penis. I went to a doctor and blood was found in a dip test but no infection. I was put on cipro whe waiting for culture and noticed no difference. I had a normal CT to look for stones. I have to wait a few weeks to see a urologist and am worried about it. I still have all the problems above. Any idea what this is? I have never seen blood in my urine, but one out of two tests detected it. I also have to try and empty bladder many times at night.
