Not all prostate cancers cause an increase in PSA, it's perfectly true, but those which do not are exceedingly rare. I understand your worry, but with a normal PSA it is overwhelmingly likely that you don't have prostate cancer. I would, however, second the advice to request a urology referral.
UCH is University College Hospital in London, one of the leading centres for treatment of prostate cancer in the UK.
It's worth noting, by the way, that localised prostate cancer typically results in no symptoms whatsoever, and specifically does NOT cause pain. The fact that you have the ache you've described is strongly suggestive that you don't have prostate cancer!
Best wishes,
Chris
