This site was set up to support people, not for a bunch of idiots to discuss what BFS isn't. BFS can be anything the S= Syndrome, Syndrome = anything. Twitchydoc seems to be able to convince everyone he has als, and has been doing so since the last time Jesus walked the earth, yet for all his crack pot theories, and his certainty that he has atrophy / weakness etc he's still here spout thing same *beep* over and over again. so Anxiety does not cause BFS? what makes you lost so qualified to make this conclusion, hell even the top neurologists arent qualified to make this determination. I'm sick of people coming into the chat room saying 'i just read this...is it true that anxiety cant cause BFS, if so I must have ALS" bfs can present in a lot of ways, but guess what, if you dont have weakness, its nothing. if you have a clean clinical 100% is nothing more serious.As to how rare bfs is, which i see was also discussed on this thread, who cares. Statistics are for scientists and insurance companies, just because something is 10000000000000000 million to 1 does not mean you cannot get it. if BFS was the rarest syndrome in the world and its benign, who gives a crap. there are two many variables to calculate, how many people actualyl get worried by their twitching, how many go to a doctor, how many dr's record a dx of bfs vs. anxiety vs. meds v. other neurological syndromes. at the end of the day, it doesnt matter.A wise Jet once told me, ALS only presents in a certain way. Weakness, twitching, atrophy. there is no pain, no sensory issues, no feeling involved. the fact that in 4000 members on here there have been No confirmed als cases, proves he is right.
