hi cat,

i also have bilateral sx's.
but my worst is my left leg.
at one point a was tx'd for a vit B12 def and i felt better. but i still had my original sx's.

i agree that it's best to know what you're dealing with.
there are meds that are recommended now (5 approved) to help stop progression. getting onboard early may help with disability down the road.

try to learn as much as you can about MS.
you might even consider a 2nd opinion. and, consider an MS specialist.

i hope you don't have MS. but don't give up advocating for yourself.
keep us posted.
