Pericarditis is the inflammation of the pericardium, which is the membranous sac that surrounds the heart. Pericarditis can cause chest pain which can become more severe with breathing or movement. I was diagnosed as having pericarditis once, though the doctors were unsure if it might be pleurisy, so at the time it was recorded as pleuropericatditis.
