I believe that as BFS is an actual nervous system condition, hence the weakness and excercise intolrance we experience is real, ableit benign and really not debilitating (hence no true loss of funtion). The anxiety caused by this weakness can exacerbate the situation, sometimes making the weakness feel worse than it may actually be. Unfortunately, I don't know of a remedy for this other than to try to not to focus on it. I can play baseball, excercise, and ride a bicycle, yet sometimes when I get up from a chair, it takes three steps before I feel steady. All I know for sure is that I can still do everything I could do before BFS, so I try my best not to worry about it.
