Before I decided to make any brash decisions, I talked to my friends...casually...about it. We were all smoking, and I coughed and the pain happened again, so I said, "Hey, when you guys cough, do you ever feel this pain in your _____ sometimes??" And, surprisingly, they all said they had felt it at some point. In fact, they're situation is just like mine, it doesn't happen every time, its only every once in a while. So, maybe its not code red??
