Yes to both question. I have forearm muscle soreness that doesn't go away for 2 months, I have some finger joints pain, I have feet pain, you name it... And I have just about the same symptoms you listed in your post
It is all "normal", for BFS at least. BFS is much more than twitching for many people and some have mostly twitching. For me it is a twitching/sensory problems/pain and soreness journay. I hope one day it will end.
