This could be a heart condition in which i suggest you should go see your doctor about this.
its in the middle of your chest, between the lungs
Air in the chest (Thorax) causes the lung to collapse. This can be spontaneous or after chest injuries
Mediastinum
Inflammation of the tissues that cover the lungs and line the chest cavity causes pleuritis, with fluid accumulating in the lungs.
The sternum bone is in the middle of your chest, right above your heart and lungs.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
plueral space
Below the neck, above the middle of your belly. Heart is located to the left of your chest.
pleuritis
i think that your lungs would be dried out.
your lungs are just inside your ribcage, from the chest in. there is your heart, stomach, spine, some arm muscles, and big arteries and veins between your lungs and your back skin. there is just the ribcage and a couple big blood vessels between the lungs and the chest.
Enclosed in its own little sac (pericardium), the heart rests on the diaphragm, between the lower borders of the lungs, the middle of your mediastinum (center chest), and in the thoracic region of your spinal cord. Essentially, if you take your right fist, place it between your L breast and your center "breastbone" that would be the approximate size and location of your heart.
