Sleeping without a pillow

I’m sorry for such a random question but it’s something I’ve been dealing with for the last couple years. I’ve tried various pillow sizes and shapes, I’ve tried sleeping on right side, left side, stomach. It all ends up in me having neck issues. From
migraines to what I’m currently doing with ( feels like my neck , shoulder, and arm are fused together, lots of pain) the only time I have any semblance of pain free sleep is on my back but I unfortunately move around a ton so I end up in the other positions anyway . Is there any reason I wouldn’t be able to try sleeping with no pillow at all ?

You can try whatever you’d like.
