Hello Larry,
In my opinion your neurologist should have shared with you what he told your PCP.
My advice - Get a 2nd opinion (and a 3rd too). Seek out the best neurologist/spinal surgeon that you can find. Talk to others you know and get their advice for an excellent neurologist/spinal surgeon. And I would also recommend that you call up a local professional sports team and ask who they use as a spinal specialist for their players.
Okay, to that difficult topic - weight Larry, I commend you for your "positives", however, you know that perhaps it would be a good idea to lose some weight. Think of your back. Do talk with your PCP about this. Okay.
Hope all goes well.

P.S., - I have about the same spine problems as you do. I am 71. I have had two epidural injections and they have really helped me. At this point, even considering my age I'm going to keep the knife away as long as I can. That has been my decision.
