I'm a Side Sleeper due to current circumstances.
So I've been using alot of Pillows to help Cushion my Body, it helps.
But on occasion I still get some Numb Fingers.
But I think it has more to do with my Old Back Injuries, that caused some Nerve Damage.
They make Body Pillows if you Sleep on 1 Side most of the night.
I use Small Pillows, cause I Toss and Turn alot to try and get comfortable.
So a Body Pillow is just Too Big for me............................................. JP
P.S.
My Best Position has always been on my Stomach, when it's Not Too Painful.
Sleep like a Stone, and Wake with Abundant Energy.
