Mike, I'm in the same boat. Maybe not as far progressed as you. But, I've been playing with back pain now for several years, and it is getting harder all the time. Last winter, I was so miserable, I didn't sleep for more than a couple of hours for months. I got a bit of a reprieve. I went to the Y all winter, and did what I could. Also, I walked a lot, and bought an inversion table and hanging upsidedown for several minutes and crunches upward is now part of my regular day. Something slipped back into place for a while, and I got back to playing, although less than I wanted to. But, I considered it a gift to get back to playing.
Now, I am also having the hand problems. It is classic carpal tunnel, along with advancing arthritis and trigger finger. I know there are operations for both of these. But, with very high deductibles and co-pays, it isn't an easy decision to take, considering that the back operations have limitted success, and some get worse.
But, I'll try to get some rounds in, as long as I can, like you. Maybe, some things will change in the treatment options. But, as you said, the constant pain becomes a greater issue to balance or trade off for the joy of the game.
I guess I"m no Pat Mucci when it comes to pain management and overcoming physical issues.
