Pain after birth

Anyone had any severe back/leg pain since giving birth? i'm 5 month pp & since i've had her my back will have the worst pain ever and more recently my leg feels as if it coming disconnected from the hip or something. it's very very VERY painful and i can hardly walk and moving it in any direction hurts even worse. my mom says it could be from having the epidural but something tells me this just isn't normal.
