Pericarditis is a swelling and irritation of the pericardium, the thin sac-like membrane that surrounds your heart. Pericarditis often causes chest pain and sometimes other symptoms. Pericarditis is usually sudden and short-lived (acute).
When symptoms develop more gradually or persist, the pericarditis is considered chronic. The sharp chest pain associated with pericarditis occurs when the inflamed or irritated two layers of the pericardium rub against each other.
Mild cases may improve on their own. Treatment for more-severe cases may include medications and, rarely, surgery. Early diagnosis and treatment may help to reduce the risk of long-term complications.
