I have been twitching for 17 months. It has never stopped but at times lessened a little. My feet and calves go 24/7, but lately so has my whole body. It jumps throughout. I looked at my upper arm today and it was about jumping out of my skin. It only lastest seconds but it looked scary, and it will be back. Then I feel my shoulder, my knee, my ribs, etc. Has anyone had them this hard and this bad? Is this till BSF?
