My right cheek is what finally made me a registered user here, and its very strong twitching, so distracting and impossible to ignore. It does not mean als, any muscle can twitch, I have been assured of this repeatedly. My face never twitched for 11 years, now my face involved. It's normal for bfs, just remember that. I am here to remind myself, i am positive but admittedly I like to talk to others with this annoying bfs, it can make you negative if you can't relate to others who understand. ANY muscle can twitch.
