This is a very structural/alignment issue. You need to be working on those things first and foremost, that means PT exercises and pilates, but be aware that pilates does not work your glute max so it doesn't replace the PT exercises. Acupuncture may help manage the pain but isn't going to get you better much faster with this problem.
I'm going to try to find the link for guidelines I gave once for pain with activity. But in the meantime you should know that any sharp debilitating pain like you're describing is not good. Aching is a different story.
