... his PSA elevation....not seeing why it is elevated because he is afraid of the biopsy causing incontinence...
It sounds like your husband lives in denial of his own possible medical issue and he would rather you do the same by just taking a couple of pills and forget about it. Maybe he is just as afraid for you as he is himself. And, if he learns to face his own health issue he will then be able to help you with yours.
I have had an elevated PSA that turns out, according to my urologist, is related to the same autoimmune that causes all my other problems. I'll tell you about it if you or he wants more info.
