I have COPD and Asthma and am on nocturnal oxygen. I also have
pain in the middle of my chest, my
neck and shoulders. My doctor believes this is my lungs, not my heart. To be safe, I have had stress tests, and a variety of other heart related tests, all come out negative. The difficulty breathing, coughing, and shortness of breath are probably due to COPD, but do you have a pulmonary specialist you can see about it or are you just seeing a GP?
