Odd Convulsions when trying to relax

Hello,

I have been struggling to figure out a condition where my body convulses with the epicenter being the stomach and lower back when i try to relax. It prevents sleep. Have you ever comes across this condition? If I had a brain scan, would that show treatment options? 

Thank You, 

Maybe you should 1 see your go and ask him for blood work , cat scan , or mri  Thdn go from there try putting heating pad in that back area see if it works . But just make sure u see your go first plz
