which side is your heart on
The type of pain that you are describing is probably not a pain coming from your heart. The reason I say this is that since the heart is on the left side of the chest, pain that originates from the heart usually stays on that side. Plus, chest pain that gets worse with taking a deep breath is usually not pain coming from the heart. The only exception to this rule is pain that comes from pericarditis, a condition of inflammation in the outer sac surrounding the heart. The pain you are experiencing sounds like pleuritic pain.
