I have been having pain in my sternum for the last two days. It hurts when I cough, breath deep, it also hurts when I lay down. It is not constant but it feels really sore. I got a fill a few days ago and I am adjusting, I ate something too fast and unfortunately I threw up. I did not feel as if I husrt myself when I threw up but the next morning, my sternum hurt do bad, it felt like I had been kicked by a horse. I have also started to cough. Any thoughts?
