Shoulder and hip pain

I'm 25wk and I have the WORST shoulder and hip pain. I think it's from only being able to sleep on my sides. Sleeping on my belly or back just hurts too much no matter what I try.

I've tried various heights of pillows between my legs when I'm on my sides too.

What should I try next? I figure by the time the baby gets here I should be able to find a good position LOL
