Pec minor/tight pec issues

Musculoskeletal injuries generally don’t cause shortness of breath, headaches, or feelings of disorientation. And, on the whole, persistent chest pain is very rarely musculoskeletal in nature. I would recommend visiting your doctor and having him work you up for other possible causes of chest pain that better fit your symptoms such as a congenital aortic stenosis or a cardiac arrhythmia

ETA: that you often experience these symptoms with exercise or exertion further supports the possibility that this isn’t necessarily related to the musculature

I’ll bet it’s your scalene, subclavius, AND pec minor

Do you do shoulder dislocates? If not you need to start asap.
