A herniated cervical disc will only cause problems if it happens to press
on a nerve root, it the disc has a mild herniation and does not come
close to a nerve it will probably be completely with out symptoms.
Symptoms from cervical disc problems include pain and numbness in the arms,
Numbness,pain or weakness in the legs or below the neck do not usually
come form neck problems.
The symptoms you describe are much more compatible with MS rather than with
cervical disc disease, but if the diagnosis was not known at the time there
was obviously some confusion.
If you do not have any neck problems at this stage, the advice regarding
cervical disc surgery should be reconsidered in the light of the new
information which has become available - ( the fact that you have MS ).
