sneeze
Mark:
What you experienced is similar to the clinical phenomena termed "Lhermitte's sign". These symptoms occur when the cord is ever so slightly touched or in any minor way disturbed. The white matter of the cord is so sensitive it cannot even stand to be bumped. That is why it is encased ever so carefully in fluid and surrounded by a tunnel of bone. It is likely that your sneeze caused a disc to bulge out slightly more and touch your cord or perhaps a vertebral posterior osteophyte may have done this as well. There are several anatomic possibilities which an MRI will elucidate. The significance is that there is a tight space in your cervical spine with very little wiggle room left.
