MMN is Multifocal Motor Nuropathy,

It is apparently very rare and I only recently got it correctly diagnosed but it has has the symptoms of faciculations in one arm one leg and half of my face as well loss of muscle and ability to use most of my left hand.

What I noticed the b vits helping was the spasms and faciculations, before taking them my hand used to get locked up painfully in a grotesque claw and I would need to use my other hand to unlock it. Now it is weak and still faciulates but doesn't lock up.

Anyway it is not a cure but my quality of life was improved by the supplements in my previous post.

I hope the best for you.
