Yep in 2006. Doc had to open up my skull in the back, bust out the C-1 vertebrea to create a new pocket for my brain stem because I was born with my brain stem hanging part of the way out of my skull. It was being pinched between the skull & spinal colume. The surgeon went into my thigh & harvested the tough material(can't remember what its called) that covers the thigh muscle to make a new brain stem pocket & skull covering. Plus he capped off my spinal cord. Took quiet a while to regulate the spinal fluid loss & getting used to the spinal cord being capped. The most horrid spinal headaches, even worse than the miserable migraines I had prior to the surgery. I never want to ever feel that kind of pain again. The bad thing was having to heal 2 areas at the same time.
