Back help

Shannon • Been with my fiancé for 8 years! welcoming our first baby boy Caiden in June
I think I pulled a muscle in my back in my ribs, anything I can do to help with the pain!! I'm not sure if the doctors will be able to help I'm in so much pain and it sucks! Only way it feels better is if I lay down :( let me know ladies! I have an ob (34 week check up) appointment on Friday!
