Horrific Body Jerking

[[de...]]

I am having terrible body jerking during the early morning.  My back completely arches backwards and I feel like I can't get it undone.  It makes me cry out in pain.  My muscles are actually sore from this.  Is this more severe than most people have experienced?  Is it possible to tough this out?

Many people have the muscle spasms/pain.  The only thing I know that may help is magnesium, several people have, from time to time, reported that it helps them.  Other than that I don't know of anything to do but ride it out, but it will go away.
