Wow, thank you all so much for all the insight and positive thoughts. I am really not a big fan of changing anything about the body, seems to work pretty good for most people. I am happy the way God made me, and don't really want to screw that up at someone else's hand.
All that said, I gotta have some faith in what's being put I front of me. Thank's to Uncle Sam, I don't get to shop around too much for a surgeon... But thanks to my current geographic location, and the 13+yrs of conflict! there are some well experienced docs close by at Bethesda/Walter Reed.
The doc walked me through my MRI, options (fuse or replace)and processes. The only plus to the whole ordeal, at the end he was the only one that understood what I want for my future and what I want for now. I am under two years from freedom, and plans of ridge lines and drift boats..... nothing but my old lady to distract me from hunting season. I want to go be a kid again, walking the river bottom everyday with a bow or a fishing pole.... Maybe even a trap line in there somewhere.
The surgeon encouraged me to start working out again, continue every form of treatment possible. I managed to sleep in a little more than I wanted to this am, so I will try and brave some rain tomorrow and do a little stumping. The gym on Friday was painful, but the best painful feeling I needed. I guess I will see what happens. I go in a month to see if it's pain and numbness I can live with, if so surgery cancelled... If not doc already has me scheduled and that becomes a prep appointment.
Thanks again all, the fusion option has so much more data to support, but the theory behind the replacement seems so good, I think I might bite.
