Wow Steve,
And the saga continues. I really thought about this and though you never really know what you would do in a similiar situation unlil actually faced with it, if your most recent x-rays show any sign of improvement, that says a lot. I doubt Dr. B would offer bad advise to save face and if waiting will cause no further damage but might spontaneously correct itself, then I think I'd give myself a little more time. If massage and pt help with the pain... well you must be thinking all these same things yourself.
The question, how much time is he talking about? Another 3 months might be reasonable but longer? How much longer?
It's your back and your decision. Making the right one
. You just want to scream.
Good luck and keep us posted. Dale
