In brief: Comorbidities

Although ms can cause problems in the arms and hands secondary to lesions in brain and spinal cord, many patients do suffer secondary complications, such as carpal tunnel syndrome or ulnar nerve problems at elbows.
B-12 deficiency is seen not uncommonly, and can affect peripheral nerve function, and a diabetic with ms can be especially vulnerable to peripheral nerve problems. (cause, see and).

In brief: Cause not known

The cause/etiology of MS has not been elucidated.
The damage in MS is due to demyelenation of nerve fibers in the central nervous system. It is like losing the insulation on electrical wires and nerve impulses do not travel normally. Depending on the location of the lesions a person may lose the use of hands. Lesions affect legs more than arms.
