I am so upset bc I had this practically my entire pregnancy with DS1. Somehow it never happened with DS2. Well, I woke up this morning to the same "pinched nerve" feeling in my back under my rib cage that I had with DS1 and I'm a little upset about it. What the heck is it?? I can't even have DH work it out bc it's under my rib cage. Also why dies it only happen when I'm pregnant?
