Hi 'Twitching Stinks' (and boy doesn't it just stink!)I noticed that you are a new member to the site so welcome. Just to let you know that I have had BFS since Sept 08 and one of my most annoying symptoms has been heaviness in my R calf which has come and gone for over a year now. It's nothing to worry about, it's different from 'real' or 'clinical' weakness and if you can ignore it, all the better!RegardsSimon
