My right hip hurts after sleep and has for 4 months. Dr says a strained muscle. Or the bursa sac is inflamed. Try an ibuprofen and stretching. Also, do I’m a little teapot side stretch.
I run alot and get the same pain. There is a thing called runners hip which comes from not stretching your hips enough. But if you do stretch a lot I would see a doctor..
I don’t run, but I had a pain in my left hip back when I played basketball. It was some kind of crazy pulled muscle & I had to go to physical therapy. Taking it easy & stretching helped.
