I had my second BA about 2 years ago 580ccL/640ccR. For atleast a year now i have been having on and off pain in my right sternum that kinda feels like a pulling sensation from my sternum to the middle of my breast, I also have pain there after sleeping on my side. The right side of my sternum has always stuck out a little more than the other but nothing that ever bothered me physically or cosmetically. Any ideas on whats going on?! I have not been diagnosed with pigeon chest just looks similar*
