When I'm sitting still relaxing still my body begins to jerk and Shake and I'm not sure what this really means I do have fibromyalgia which I was diagnosed with 5 years ago I turn 50 in November of last year but in the back in February I started to notice that when I was relaxing my body would just jerk and now when I'm just sitting or holding something I see that I'm beginning to shake and tremble but you can't see it but I can feel it and I get my hands and everything goes just really limp
