Severe hip pain after an injection at the hospital?

I went to the ER yesterday for severe back and shoulder pain after moving the wrong way. The doctor ordered Morphine and Phenergan injections. The nurse injected the morphine into my left hip and the phenergan into my right hip. As soon as she pushed the needle into my right hip, I got a really intense pain in my hip that radiated down to my right knee and my kneecap felt like it was going to explode. Now, I still have pain in my right hip when I move my leg and I'm worried that she did something wrong. Should I be worried? Is it possible that she damaged a nerve? Thanks!
