I can't figure out why. I can't lay on my back or stomache if I lay on back or stomache to long it's Luke my body locks up and thorns. And my lower back hurts so bad I have to hold my breathe to get up
I'm not sure what, if any, questions you're asking. The simple solution is to lie on your side, and get up more frequently.
I have NEVER been able to sleep on my back!
