Anterior heart pain

Precardiac pain is mainly seen in the fibrin exudative phase of the inflammatory changes of acute pericarditis. There are no pain nerves on the inner surface of the visceral and parietal layers of the pericardium. The outer surface of the parietal layer below the fifth or sixth intercostal level has the pain fibers of the iliac nerve. Pain only occurs when you are dying. Anterior cardiac pain is often caused by changes in posture, deep breathing, coughing, swallowing, and the supine position, especially when the leg is raised or the left side is supine, and it is relieved when sitting or leaning forward. Pain is usually confined to the substernal or anterior cardiac area, and often radiates to the left shoulder, back, neck, or upper abdomen, even to the lower jaw, left forearm, and hand.
