It's really great to meet you! I'm so sorry for the problems you're having with your back. I had both a neurologist and a neurosurgeon explain that stuff to me, but basically what it seemed to come down to was that the soft tissue between the bones or the vertebra of my spine were bulging out in one place and letting two of the vertebra rub together when I bent over in a certain way. Your problem sounds a little more complicated, though. I would definitely recommend that you research it thoroughly before going through any surgery or anything like that. I hope you come back to visit us from time to time, and let us know how you are doing. Good luck and the best of wishes to you!
