I had no symptoms at all ... NONE! Had my yearly physical with my GP a year ago tomorrow and, of course, she ordered up a PSA test since she had missed that liittle test in previous years. It came back a slightly elevated 4.8, so she sent me straight to a urologist who performed a very thorough DRE (ouch)
He felt an ever so slight nodule on the central core or the prostate so he immediately setup a biopsy which came back positive for cancer on 4 of 12 needles. The rest is history. I'm at the 8+ month mark and have had two "undetectable" PSA tests since the surgery ... so far so good. Sounds like you have done your research and I tend to agree with your self diagnosis. Let's hope that's all it is buddy!!! Best to you!
