The pain you describe sounds very much like pain of the chest wall that includes the ribs, muscles, cartilage, intercostal ligaments and nerves. That is it does not sound like pain from the pleura, lung or any of the underlying organs. The most likely cause would be a physical degeneration and/or separation of ribs and cartilage but a condition that primarily affects the nerves. Intercostal neuritis could also cause such pain. The body's response to such pain is to take more shallow breaths and then, in response to that, to take a deeper breath to expand the lungs, in this case, a yawn. Any abnormality of the breast bone, also called the sternum, could also contribute to your pain.
You might wish to seek consultation with an experienced pulmonary specialist or a, non-cardiac chest surgeon who has had extensive experience with lung surgery and, hence, with the chest wall. Another possibility would be a pain clinic, with a specialist with a special interest in this type of chest pain.
I was wondering about that. I have never had asthma problems. However, I just moved into a new apartment on a lake and several friends of mine who do have asthma have had really bad problems when they come over. I am wondering if there is something in the apartment that is doing this to me.
i yawn alot and have trouble getting a full chest of air. i know that it is asthma but mine is strange. you may very well have two different problems but asthma sounds like it is there
