I'm a 42 year old female ... For the past 2-3 weeks I have had, I guess what would be, muscle spasms through out my whole body but more noticeable in both my legs. It is like a constant throbbing/snapping feeling that travels all over. I also have many "jerk" movements in my sleep where it feels like it starts on the left side to the right in the breast/under shoulder blade area. I have had no fever but have had chills. Any suggestions/comments on what I may be experiencing? Heather
