I have had BFS on and off for 17 years. It just started up non stop again about 9 months ago. My entire body is like a popcorn machine of twitches. Went back through the entire set of tests again from my doctors. Only thing that has come up is Peripheral Neuropathy in my feet. Trying to deal with the foot pain the best I can. Taking 300mg of Gabapentin and really not getting much from it. Try not to go down a rabbit hole mentally with this if you can. My Neurologist can't let find a cause of the Neuropathy.
