I started to fuse in my lower back at the age of 28-32, then remission for a long time. When it came out of remission, it rushed in like a roaring lion. Just a few months ago, after my last M.R.I.s, I have 20% left of my neck left to fuse but I feel it tightening up daily now. I move it and still fuse it but it helps, I think with the pain and lessens my migraines. Thoracic is well under way and I have a lot of rib involvement, feet and wrists are getting really stiff. I wish they had TNF blockers a long time ago. It is hard and sometimes scary but I am thankful for the people here who have helped me so much with knowledge ahead of time.
