how is your internal and external rotation?
i had some trouble with my hip (but it sounds like it is different from yours??) where i would get a weird stabbing kind of pain at the front of my femur. felt like the head of the femur was ramming into the front of the pelvis socket. would hurt to raise my leg.
i think (after much help from here) it was anterior femoral glide syndrome. maybe congenital. or maybe a congenital component (have had clicky hips from childhood). it was definitely aggravated by my doing a whole heap of quad / psoas stretching, though, because i thought the psoas was tight and needed to be stretched out.
what fixed things up for me (and my hips now feel 100% like they never have before) was stopping with the quad / psoas stretches (except lunges or stretches that also involve glute activation). not sure why... but glute activation seems to help the head of the femur stabilize properly in the socket so it doesn't hurt.
also working on internal rotation. bit hard to describe. sitting. knees up and feet flat on the floor. rotate the knees in and the ankles out. gradually... i can get both knees touching each other resting on the ground with my ankles close in by my glutes. can wiggle into good lumbar curve, too. not sure why but it seems to help pack the joint in a good way and my squats (external rotation / leg raise) has never felt better.
not sure if this is helpful for you.
