For the past year (I think) I've had a slight, very mild pain that was very subtle in my upper left back, kind of on/underneath shoulder blade. Over the last couple months it's become more pronounced, but only when I make certain movements. When I'm still, I can kinda feel it, but it's causes slight pain when I move my left arm and turn my waist at an angle. One day, a couple months ago, the pain was more aggressive and sensitive to more movements. It hurt when I moved my arms, twisted my waist, etc. I thought it was a pinched nerve and tried to massage it out. The pain subsided the following day, but I don't know if the massage had an effect on this or not. The last couple of weeks, the pain has become more present, again, only with movement. I became concerned if it could be associated with my lungs when within the last week I've had a bothersome dry cough/itchy throat with no other symptoms, and the last month or so I've noticed that when I do I quick exercise, I feel out of breath fast. To note: I've gained weight the last year. I'm confused if the pain lives in the muscle area or deeper in my lungs or something. When I breathe in deeply, there's no pain, discomfort, etc. Does this sound like something associated with lungs? Should I see a pulmonary doctor about this?
