The spinal cord is only about as wide as your thumb. It carries sensation to the brain from the arms, legs, and trunk and transmits signals for movement below the head. When an attack occurs here a person may have problems controlling the movement in the legs or have weakness that is worst in the legs. There may be a certain level over the trunk below which sensation is affected or movements are no longer under control. Many problems here too, will be temporary and tend to happen along with inflammation in this area.
Some people feel a band like pain around the torso or chest.
There is often a shock sensation that travels down the trunk or into an arm or leg when the head bends forward called a Lhermitte's phenomenon . It is caused by myelin being affected in sensory tracts in the spinal cord of the neck and electrical impulses crossing between individual axons. Double vision is temporary. It happens when tiny eye muscles don't move the eyes to keep them parallel. The visual image focuses in different areas of the retinas in your two eyes, too far apart for the brain to merge them.
