Hello Robin and welcome. First of all there are a lot of reasons besides cancer that your husband's PSA could be on the high side, e.g. an infection, extra large prostate, etc. And the pains that he is experiencing are almost certainly not from prostate cancer even if that is diagnosed. Distant metastasis generally only occur with advanced prostate cancer at much higher PSA scores than your hubby has.
What he should probably do next, however, is consult a urologist who can help figure out what's going on. He will undoubtedly perform a digital rectal exam to see if he feels any abnormalities and will order another PSA test. He probably will order a round of antibiotics to see if that brings the PSA down. He may also order a PHI test https://www.mayomedicallaboratories.com/test-catalog/clinical+and+interpretive/113000
that provides more info than the PSA test alone; you should ask about
this. Your husband should refrain from sex, bike riding or any other vigorous activity that might affect the prostate for 48 hours prior to the next PSA test.
This may well be something other than prostate cancer but the odds of us old men having prostate cancer are about
equal to our age, i.e. a 60% chance at age 60. However, many of these are never diagnosed and never need treatment. Even if your husband ultimately gets diagnosed there is a chance his cancer will be low end and only need to be treated as a chronic condition. And even if diagnosed as a higher grade our cancer is generally very treatable and his prognosis is likely to be that he will eventually die of something else.
But we're getting ahead of ourselves. Follow through with a urologist and check back with us for support and advice. That's what we are here for. You might also share some more info such as your husband's age and whether or not he has existing urinary issues like BPH.
