Opening up that area really helps for me. Not sure if it will for you. ☹

I get on my bed on all fours and open my legs up and rest my upper half on a pillow. And just let me legs open up. It stretches my joints out and is kind of uncomfortable but once you lay there for a bit it's soooo comfortable. I some times fall asleep in the position. I love it so much.
