i saw a urologist several years ago and he performed a digital exam of prostrate, all fine. had ultrasound and flow test followed by procedure to clear any blockage, got little relief for a short time, it has been giving me trouble ever since. as i say that was several years ago. it was my GP who thought it may be an infection but as i say the lab results were indecisive and the follow up test was infection clear, but symptoms continue, just put off going back . some days it is ok then it flares up again.
