The cervical spine is the usual area for MS to affect - it does not usually cause lesions in teh thoracic or lumbar spine. It usually causes lesions higher in teh brain though - have you had a brain MRI? Perhaps your diagnosis (made 23 years ago) needs to be reconfirmed to see if it was really MS - this can be done with MRI of the brain, and spinal fluid analysis. Even though you had no symptoms we know now that, in MS, the brain may still be accruing new MS lesions. There is treatment for MS to slow the accumulation of lesions and prevent relapses.
Devic's is an aggressive disease, usually resulting in blindness and spasticity over a few years - this does not sound liek your case. You should seek expert advice though from an experienced neurologist.
