Do nerves completely heal in recovery?

Just wondered when people say they "recover", do the nerves completely heal or still shake or twitch under duress sometimes. That's where I feel that I am right now at 9 months out. Just wondered if this was normal for GBS or MFS or both at this point out.

I had MFS and am at a year now. Most of my nerves have stopped twitching, but they still twitch a little in the areas that aren’t completely normal yet (mostly my eye and lip muscles), but it is pretty mild and infrequent now. I had strong twitching pretty much everywhere before, but it really does seem to be related to the healing process (I’d get twitchy in an area, and then I’d notice an improvement in that area soon after).
