Have a neuro
surgeon check the films carefully for Chiari Malformation. This is the herniation of the cerebellar tonsils in the lower back of the brain. Chiari (or "Arnold-Chiari," or "ACM," as it's often called) is often mistaken for MS, so
any degree of herniation should be taken seriously. If one is found,
do not allow it to be blown off as "a minor incident that has nothing to do with the symptoms."
Good luck!
