I am by no means a medical doctor or a secientist. Although I am going to put foth a hypothesis that BFS may be incresed by anxiety - and people with anxiety problems may be more prone to BFS. This is why........In my own cases I know the twitching has flared up in times of stress once when I was moving from my hometown and the most recent over being worried about my health.One thing I noticed in going over the surveys is almost everyone here with BFS was terriefied of ALS some people even thinking they wee dying. All this even though they may not have actually had any symptoms of ALS (being disbalanced, clinical weaknes, and inability to do basic daily activities). I sometimes have the same irrational fears of minor symptoms being something big. Looks like us who have anxiety over small thngs being catastropic are more prone to this twitching.Of course I have no scientific proof but i feel confident this twitching is liked with anxiet or people who have a tendency to feel alot of anxiety. Any thoughts?
