How many other doctors, besides your chiro, have you been to? How many other opinions have you gotten on this? I wouldn't resign yourself to living in that much pain. I would go to a chiro that specializes in applied kinesiology and see if they can uncover anything. I would go to a specialist and show them your x-rays and get their opinion as well.
I can't imagine being in that much pain, and having to deal with little ones on top of it. You poor thing.
