Can a naturally fused neck vertebrae c2, c3 & c4 be taken apart so normal movement be obtained again? I was just told they have fused. It could have been caused by any or all if my past issues: too much chiropractic adjustments over 40 years, or because I was hit from behind in the car at a sitting stopped position or because I was given Flagyl medication 4 different times,and each time I took it it caused my neck muscles,& tendons to freeze up, never to release even after deep tissue massages. With lack if movement it may have caused the fusion? Or the Dr. Now says I have RA but it may be a result due to chronic GI issues over 15 years. I want my neck movement back.
