S.B.
I think you might want to consult a chiropractor.
With both of my pregnancies, I had problems with my hips rotating out due to the added weight of the babies and I had problems afterwards as my body tried to readjust to not carrying that weight anymore.
I couldn't have made it through without my wonderful chiropractor. It made all the difference in the world for me.
It's worth a try. You may experience great relief. I know I did.
Best wishes.
