Back and rib pain

Hello I'm 6 weeks pp I had an emergency c section I was fine and now I've started having back pain and bilateral rib pain...cramp/spasm so bad at times i want to curl up in a ball... I've been taking ibuprofen with some relief.. Called my OB but still awaiting a call back I was wondering if any other moms were having or had this issue if so how did it resolve?
