Hello, the middle of my upper chest hurts (especially when i sneeze). I wet to the doctors to ask about that and the bump at the end of my sternum. He said the bump on the end of my sternum was just a deformity and the other one is just ribs rubbing up against other ribs/ upper part of the sternum. There is an inflamed area on top of there and i get a sharp pain when i sneeze. I will also get light headed when i try and stretch that part of my chest. The problem has been going for a couple months now and i think it is getting worse. (not sure if this applies, but i attempted once to stretch it after a workout and i got really really light headed and my hearing in my right ear got worse.) Thankyou
