What Causes Syncope, Pain In Inner Left Thigh And Pelvic Area?

I fell during an episode of syncope from a sitting position. I became wedged under a bench on top of concrete during the episode. Now, I have a terribly sharp pain in my inner left thigh / pelvic area and my outer, back side hip area on the right. I fell on my right side with the left hip jammed under the bench. I cannot bear weight or lift my foot more than an inch on the left side. Not sure what to do...
