Any suggestions for hip pain when going from sit to stand. Pain is lateral near iliac crest.?

Sartorius/TFL/Glute. Seen in athletes as well. Evalualte the muscles that originate off the asis as well as the glute max and med off the iliac crest and wing. Have to look at back and hip xr too and look at the wing even with possible judet views. Is the patient older? Wearing a belt (officer)? Athletic? Muscular imbalance?
