@robson78 Here are a few things to think about. What levels are these? What condition is the level below looking like? Did he give you a prediction of how long it would be for the lower level to get worse if you don't fuse it now? If he does 2 levels, would all of that be without hardware? Did he explain how much motion you loose by fusing these 2 levels as opposed to only one? I have C5/C6 fused and it isn't very different than before fused because that doesn't restrict head turning.

I understand the fear part, but you know a lot about this already since you've had a disc replacement. You'll need patience for the recovery and it will be worth it. After 3 months in a neck brace, muscles are weak and will tire out and you'll need some rehab therapy. I was fearful too and learned how to conquer it. What concerns you the most?
