While you have many neurological symptoms to deal with, not having MS would be great. Is your new neuro going to rule out the usual MS mimics, such as Lyme disease? Ask for complete blood work, including the test for Lyme disease.
Also, if you haven't been seen by a neuro-ophthalmologist for your loss of eyesight, try to schedule an appointment with one. Do you ever wake up with loss of eyesight? Is that the only time it happens? Do you ever have pain in or behind your eyes? If yes to all three questions, your loss of eyesight might be like mine which happens because in my sleep, without knowing it, I rub my eye(s) so hard due to Optic Neuritis pain that the blood supply to the eye(s) is stopped; sight returns within a couple of hours or less. The prescription drug Keppra has helped greatly to reduce my eye pain.
It's wonderful news that after 20 years, your brain and spine are in such good condition, lesion- and atrophy-wise. I'm very happy for you. Try to relax and focus on the differential diagnosis of MS.
Best of luck.
