Welcome, sorry you find yourself here. My husband's neuro had a similar reaction looking at his first MRI. Her words, "Do everything you can now." He had so many lesions, and one biggie on his cervical spine. She was surprised he was doing as well as he was. Neuros don't know what the future holds, or how your body can re-route itself. Brain plasticity is an amazing thing. Neal Cavuto is a wonderful example of that.
A year and a half later, my husband's second MRI showed no progression and some slight shrinkage in lesions...and again his doc scratched her head. Your future is not written, Sky. Do all you can with diet, supplements and exercise. Take a CRAB if you feel comfortable with that. Rely on how you feel and live in the here and now.
wishing you the best,
Husband dx RRMS 3/07
dx dual jugular vein stenosis (CCSVI) 4/09
