HI Nervous,
I hope with more information, and with more time, you will feel better prepared to deal with whatever comes your way.

Any chance you have an automated bed, as in an adjustable frame bed?
I am asking because at least some of these have an EMF and many report worsened nerve pain, spasms and worsened burning in the night.

If one has an electricty run adjustable bed frame, unplug the bed and see if you notice a difference? This suggestion goes for anyone with pain, tingling, burning, spasms and an adjustable bed frame that plugs into an outlet!
