Neuro #1 told me that fasiculations while using a muscle are just as likely to occur as when not using muscle. Neuro #2 told me that he understands where people get that idea (the internet) but for him, it does not matter. I'm with you on the soreness. Just part of the deal it seems. My calves will be sore for no reason at all, although since I've been running for months, that seems to be getting better. I will also get sore in my hands, wrists and forearms. And if I sit and think about it, it's not a lot of pain and if I wasn't so in tune with all this stuff (so hyper-aware) I probably wouldn't think twice about it. So, this could be completely normal even outside of BFS, although I'm convinced that BFS does play into this. Either way, par for the course. Easier said than done, but try not to worry/ think about it. Cheers,Michael
