Is there any way that you could send copies of your x-rays to this new surgeon to view, then schedule a phone call with him? Maybe that way he could give you his feelings on if it would be a waste of time or not to fly cross country to see him.
If this was Eric, I would move heaven and earth to keep him walking.
Some of the old timers here may remember that I did nudge it when he was not able to walk, to get the meds he needed...If there is a chance for you to walk, then take that chance and do it!
Good luck, and please let us know how you make out.
