I love these little half moon pillows. Half Moon Pillow
I usually find them at CVS as a single though and they can come in a variety of softness. I like something that is firm with a little bit of give so it can lightly/gently cradle my head without aggravating my pain I get around my ears.
So when I sleep I usually sleep on my side with my arm over a pillow and then the half moon between my arm and my head.
I have tried a bunch of pillows and so far this has been the best for my pain. The only other one that came close was the ‘boyfriend’ pillow where it is like a candy cane shape and it offers a little more support in front of your face but I felt that was pushing my head back putting too much pressure on my skull.
