Hi Joann. Your dr doesn't seem to be aware of what patients with lung issues go through physically. Throughout all of the years I suffered with my chronic lung issues; chest and back pain were a part of it. I had a 'rotten spot', the name I affectionately gave my one painful place on my back. It was near my right shoulder blade. I suspect that I may have torn the mucsle there from years of chronic coughing. I probably kept re-injuring that muscle every time I coughed. The same may be true of muscles in the chest. Acid reflux can cause chest pain as wel,l and often accompanies lung disease. Many members on this site have stated that they too have had chest and back pain accompanying their lung diseases. Think of it like this: if you take a yard of material and grab it in the middle and twist it; the whole yard of material is affected. The body is a lot like that yard of fabric, especially when it comes to connective tissue like muscles. Does that make sense to you?
