@robson78 Thank you for asking. I has been 6 and a half years since my one level C5/C6 fusion and I don't have neck pain related to the fusion. My head turning is full range the same as it was before surgery because C5/C6 doesn't do much toward head turning. Periodically, I feel the scar tissue tightness from the incision, and take my hand and stretch that out. The problems I do have are because I also have thoracic outlet syndrome which makes one side of my neck too tight, and a muscle spasms can actually start turning my vertebrae. As long as I keep all that aligned properly, everything is fine. If things start to twist, I get a one sided headache on the back of my head, or jaw and ear pain until can stretch and get it realigned again. I have worked with a physical therapist o this. I think it is importation to keep my neck lined up correctly to reduce wear and tear on adjacent discs as I do not want to need another spine fusion.

Do you have a surgeon who is going to revise your artificial disc surgery and perhaps do a fusion instead? I know that bone growth around an artificial disc is a risk of that surgery.
