It sounds somewhat like the flare that sent me to a neurologist several years ago. The twitches drove me crazy. Also had tiny and not-so-tiny muscle cramps just about
everywhere. I underwent testing, but nothing specific showed up.
The good news is that it gradually got better. I no longer remember how long that took, but I do remember being miserable for a few weeks!
Have you been checked by a neurologist? It really gave me peace of mind to do that.
Hope things are better soon! Keep us posted.
