What could this be?

So I'm 14 days PP. I had an elective c section.. now I've had this really severe pain in the top of my left leg for atleast 8 days.. kind of in between my pelvis and top of thigh.. I mean its extremely painful.. too the point where I'm walking with a limp. It hurts to turn around in bed or even sit in certain positions. It kind of feels like my bone is gonna pop out of place or something..the more I move or walk about the more it hurts. Has anyone had this? Is it normal or is it something bad? Any idea what it could be?
