Hey Carol. My lupus symptoms began with CNS issues including the jerking, but with plaquenil etc, the jerking subsided for many months. Lately every time I flare I become a jerk. I especially notice it when my body is at rest. Some part (muscle/tendon) must be in motion constantly and it's jerking, not twitching. It's just like you descibe- hand jerks, then upper leg, head, back- all random and continues for 30 minutes or longer. I'm seriously considering asking my rheumy for a neurology consult. Carol, I'm sorry that you've also become a jerk
Many hugs!
