I can’t sleep either.
I sleep on my right side my sciatic nerve in my right thigh starts throbbing after a while.
I roll over and sleep on my left side my sciatic nerve in my left thigh starts throbbing after a while.
I turn over and sleep on my back and my lower back starts throbbing.
I roll over again on my belly and my arms start hurting after a while.
Drives me CRAZY!
ARGH!!!!!
Try sleeping on someone else's belly. Always worked for me.
