i wish i was a doctor so i can give more sound advice....
mike, the hip socket is actually located behind/posterior of the sh injury site, so that is prolly why docs are thinking it's your hips. that happened to me as well. a hip guy finally said its probably a sh and get it checked. too many people have said to leave those labrums alone! there are lots of people out there who had the surgeries with no releif.
hip impingement is also related to sh injuries in some schools of thougt. http://www.hipfai.com/
but apparenly lots and lots of people around us have tears in their labrums. mine was positive and then the other week an mri didn't show one. hmm.
but, i had the same symptoms with my thighs being externally rotated. do either of your knees feel like they buckle in? does one of your feet (or both) pronate and/or pigeon toe in?
my legs no longer point out like yours. feet and knees are straighter than they have been in years. i still get pains while stretching- especially the lunge/psoas stretch, groin stretches, and hamstring stretches. so i stopped for a while. that allowed me to heal more, now i am aobut to start light yoga again.
i have heard that the idea of releasing adductors and other tendons is nuts. those tendons will not heal. what your body probably needs is to lengthen the fascial encasings around the affected muscle compartments. manual therapies can help (above posts).
in my opionion, go see um in germany. with so many of these under her belt, she has seen and treated many variations of it. the labrums should wait till way after any needed sh surgeries, you might find that the labrums can stay as is.
hope it helps, wish i knew more...
