Hi Fabby, I think I know what you mean, Ya almost want something to be able to be surgically fixed. Wouldn't it be nice f w3 had the super surgeries you see on discovery. That show is depressing, they do these amazing things but can't fix or fuse or gaurentee anythging.
Let us know what you find out, of course get several surgical opinions and there is no reason your Pm doc can't work on the increased pain, I don't get why he wouldn't. It really is all about quality of life and why bother with all we go throgh for pain management if it's not managing our pain.
I could rant too when I here about being bed ridden when they can do better.

Take care. Dave
