Can Muscle Pain Cause Severe Pain?

Hello, I had a ski injury today in which I fell coming off the lift...sorry, that's as good as it gets...I landed on my left hip and shoulder. Initially they both hurt. Th shoulder pain gave way to achiness after a short time but I was unable to move my leg without sharp pain. X-rays revealed no fracture so we attempted a trial of ambulation. The pain was still severe and did not correlate to the injury. A ct was done which again, shows no fracture. My question is this...can muscle pain cause such severe pain. I am barely able to bear wt on the hip. But what's confusing me is if I extend my leg out, the pain is not too bad, but put in front of me as a normal walking movement causes knife like pain in my hip...?..
