Spinal disc replacement surgery?

It's really not an elective thing. I had two different spinal surgeries that had to replace and fix collapsed into my spinal cord. If not I'd not be walking and the pain would not be manageable at all! A neurosurgeon would do a discogram and other MRI's to deem if it's necessary... I'm much better after my spinal surgeries and have about 5 different gadavers. From different ones.
