This has been a fascinating series of posts. I have had the fasiculations mostly in my legs for 14 years. It started about the time I started developing the strange symptoms in my feet finally diagnosed as axonal loss polyneuropathy just last week after an EMG. My neurologist essentially blew off my years of fasiculations as "inherited, certainly not ALS." I knew they were not ALS, having had them for 14 years. Come on. I find the fasiculations "go nuts" after certain sorts of exercise and other times, like right now, just sit there and flutter at a low level. I am rarely without them, but I have never had them with "electric shocks" as mentioned in the initial post. I will leave that to my largely dead feet and ankles with the random electric shocks and zaps.
