I just knew my hip was not the primary cause so I kept making new appointments with new doctors. Finally a friend suggested I find a Regenerative Medicine doctor. I went to Spin and Pain Centers in Tysons, VA and found my answer.
Prolotherapynashville.com has a very comprehensive write-up of how ligaments got lost as a diagnosis. I am an old lady and remember when we all heard about ligaments. A ligament that is "lax" needs to be touched to be diagnosed evidently. They were however, mapped extensively back in the 1960 by a Dr. Hemholt as the pain location is not necessarily the problem spot.
Hope that helps
