How would you best describe FMS symptoms to a doctor. In my particular case, sometimes it's as though I feel like i'm having an "out of body" experience with the exception of me returning to my body. As I find myself waking up from a sleep, I can feel my heart racing along with the feeling of circulation that is taking place within my body. It's as though someone has plugged a microwave into my body, followed by stiffness and pain. Has anyone had this type of consistent "rude awakening."
