Help! What sleep position with bad shoulders

[EvaHarknessRose]

I’m a side sleeper, I start off on my left and then move onto my right. But I think it might be aggravating an achey right shoulder and the left isn’t much better.

I’m trying to sleep on my back, I’ve tried V pillow, wedge pillow, flat pillow, pillow under knees, no pillow. I’m going mad. Nothing is really comfortable, and when I do lie on my side now I can’t seem to figure out where to put my arms. What is best? What do you find comfortable?
