That is a nice link. I use the forum at www.aboutbfs.com very insightful.
I have had BFS for nearly 2 years know and for me it is nonstop action in my calves just have to live with it and understand even though it can present like it could be linked to als, It is a totaly different thing as it says Benign.
One day it would be nice not to see my muscle's twitching/spasms looks like popcorn popping all the time and feels like snake's under the skin.
But thats life.
