Chest pain muscular
Yes! chest cavity
has muscles outside, then the thorax and ribs, then the organs inside [lungs, esophagus, heart
, blood vessels, and the muscles inside the chest to handle all those vital organs]=any element can have its own symptom but as there is no sensory nerve
inside, what you feel can not easily attributed to any organ.
Even blood test and scans at times do not help id the source.
