What Causes Pain And Bleeding From Penis?

I am seeing a urologist on Friday, but am a little concerned. About 3 years ago, i had a lot of blood come out of my penis after a very painful wee. The hosiptal put me on antibiotics which seemed to cure it. The doctor did a physical examination of my prostate and said all was fine. They lost my urine sample, but as the symptoms ceased, I didn t pursue it. Now 3 years later the problem.has returned and I am a little worried. Nowhere near as bad as 3 years ago. I have taken a full course if antibios, which stopped the bleeding. Was still a little painful. Then today, the bleeding has started again.
