I guess I just experienced my first intense "hot spot" of twitching since this all started about 5 months ago. Although I have some minor hot-spots in my thighs and calves, I never experienced twitching like what happened to me this weekend. 4 days ago I started having constant, nonstop twitching in my left tricep or deltoid muscle. It was very bad, constant and did not let up for almost the whole 4 days. Up to then my twitching was intermittent and sporadic. However, this really scared me because it was constant in the same muscle. Since I have a c5 pinched nerve on that side I thought perhaps it might be more than just the BFS causing it. It was so intense it scared me to death, in the past my hot spots would only last at most a couple of days, but this time it was 4 days without stopping. This morning when I woke up it was gone. The muscles feel sore and achy presumably from the constant twitching.What in the world causes these hot-spots and these intense episodes? Does anyone have similar experiences where the hot-spots lasts for days?Jim
