I Just Had A Baby On March 31 And Was

I just had a baby on march 31 and was feeling ok until a week ago. I lost my balance but didn't fall. Now I have pain in my right hip. It feels worse the more I move around. I feel a sharp pain inside my hip towards my buttocks. If I turn my foot to the side, if I put weight on my leg or try and extend my leg away from my body. I can barely lift my leg and am wondering if I should go to the ER or call and wait for my doctor to see me. It's pretty painful and since I can't walk properly its now causing pain in my other leg lower back and feet
