I had a chiari decompression 2 1/2 years ago. After surgery my symptoms were much improved. Last December I had seizure in which I went face first into the floor. I broke my nose, knocked out teeth, and injured my neck. My neck is not improving and, in fact, getting worse. Many of the Chiari symptoms have returned. Can a neck injury cause a repeat Chiari problem? I have had a neck x-ray, but it is fine. The doctor sees arthritis, but no sign of fracture. A fracture was a concern since I have fractured many of mine due to osteoporosis. He has told me it is just arthritis and I would have developed this problem anyway. I just can't agree. Other than when I had the Chiari, prior decompression, I have never had any neck problems. I find it odd that all these problems developed after injuring my neck. If it is arthritis would I not have noticed a problem prior to the injury? I do have an arthritic spine, among other joints. But why would it suddenly be so acute after an injury and not improve?
