Well, Richard, I don't know how much my experience will translate to your situation, but for what it's worth - in '96 (when I was 12 years older than you are now, and no longer a notably fast healer) I had carpal tunnel release surgery on my right hand. I am not now, nor have I ever been, a pro player, and most of what I do is finger-style accoustic guitar, but IIRC I was playing again within a month or two with no noticable decline in my chops - though it took a couple of years to get my full grip strength back. Where the descrepancy between us lies is that my chops were excreble to start with, and there is a difference between playing a big string of .047 and a little string of .045, so my experience might not translate directly to yours. While I can understand your trepidation, I must say I've never regretted it - pre-surgery I was spending most of my time holding my right arm against my body and damn near crying from pain; post-surgery I had a month of being whacked out of my gourd on Vicodin, and then no more pain or numbness at all, ever. However you decide, good luck, and keep us posted.
Peter
