Pericarditis occurs when the membrane that surrounds the heart and its major blood vessels becomes inflamed. In most cases, the cause of pericarditis is not known. It can be caused by a virus, a heart attack, chest injury, or another illness. Pericarditis causes sharp chest pain, which gets worse when you lie down or take a deep breath. The pain gets better if you lean forward or sit up.
Pericarditis often heals on its own and usually does not cause any further problems. Most people recover within a couple of weeks.
