Hi Laura and welcome. I am not familiar with this problem, though a friend of mine is going through it right now and will be having surgery next week. I will try to remember and post here again and let you know how that went and how she is doing.
Good luck. I'm sorry to hear about what you have been going through this last year. I think a lot of us can releate to the constant beatings and the depression that inevitably follows.
Hang in there. it's tough to do...but you do have support here at least. getting back into yoga sounds fantastic, it might boost your confidence and at least be soul soothing.
have you looked into considering a spinal health specialist? they do all sorts of therapies and management of spine and vertebral problems. there are also hospitals that are specified just for spinal health and rehab.
stress on top of illness makes everything a whole lot worse.
