I had pain that was very localized because of a torn labral. So, the pain was not radiating from somewhere else and was in fact coming from the joint itself. When doctors ask me to identify the area of pain, I always pointed right through the middle of my thigh, straight down where the joint would have been.

I also had groin pain as well. I was told by another doctor (before I ever had the right diagnoses and well before I ever heard the word Ankylosing Spondylitis) that pain to the outside of the joint/leg is likely bursitis or tendonosis and though connected to the joint is not the joint itself.

I'm not 100% sure what you are asking, but hope that helps.
