In desperate need on how to relieve sciatica pain to sleep comfy.

I hope someone in here also suffers from this so they can shed some light.

So ive recently gotten nerve damage on the sciatica nerve and I cant for the life of me get comfy in bed. The "best" is on my back, but its not fool proof and I hate sleeping on my back. Google told me to put a pillow between my legs, but either Google lied, or I alone can't get it into the right spot it needs to be.

Went to doctors yesterday and im on muscle relaxers for a week. For now though I need help as im EXHAUSTED.
