Oh man, I remember my bout with an ALS scare once several years ago. Also being OCD, I would get twitching ALL THE TIME especially in the legs, and then have to try to test myself by standing on the tips of my toes to see if I still could, or scare myself into thinking that I was getting ALS if I couldn't. I never got a diagnosis for my muscle twitching but several years later, I can still say that I'm twitching, albeit not as much but I have chalked it up to just BFS as well.
