I have bullous emphysema and chronic Atelecasis. I've been having very sharp and ripping stinging pains in my chest that come and go. They can be so sharp that I gasp, grab my chest, and moan. Totally unpredictable and I can't control it. It embarrasses me when I'm in public or around someone who doesn't know my condition. They started two years ago, but the last few months they come everyday, multiple times a day. My recent chest xrays show the bullae are stable and its not pneumonia. Has anyone had this symptom? It really concerns me.
