question: Hello doctor, I have a prostate congestion issue that comes and goes from 2 years. Lately I am having a slower urine stream even slower than the times I had my prostate congestion before, also I am having uncomfortable feeling above my anus, itchy or uncofortable feeling at the tip of my penis, and some discharge from my penis. I had my tests done. Urine and semen culture, swab from the tip of my penis, and C/S for my urine and semen. Before the results doctors been telling me that I might have an STI and they gave me a one time injection with 4 tablests of antibiotics. When the results came it showed no sign of any bacteria in all my tests, the swab is clean no STD. I only had a higher WBC count in semen culture which was around 10-15, where the normal reading was 0-5. My doctor told me thay I have an infection in my prostate or inflammation. He gave me anti-biotics for 10 days and an alpha blocker medicine. He did not do physical check or ultra sound. I need a second opinion, I am afraid I have a cancer, it does not make sense to have an infection without bacteria discovered in all the tests?
