Guide to Signs and Treatment

Acute Pericarditis

In acute pericarditis, chest pain is caused by layers of the pericardium rubbing together or the heart rubbing against the pericardium, which can feel like sharp or stabbing pain and can even be mistaken for a heart attack.

The chest pain is often in the center of the chest, but it can also be in the neck, left shoulder, or back. The pain can vary from person to person and feel either sharp or dull.

The pain may get better when you sit up and lean forward and worse while you are lying on your back, says Dr. Anavekar.

Other symptoms of acute pericarditis include:

  • Fever
  • Shortness of breath
  • Fast heartbeat or heart palpitations
  • Muscle aches and pains
  • Hiccups or trouble swallowing
  • Dry cough
  • Anxiety or fatigue
  • Swelling of the legs, feet, and ankles (in severe cases)

Recurrent Pericarditis

Up to 30 percent of people who have a first episode of pericarditis have recurrent pericarditis, which is when the condition returns after having no symptoms for at least four weeks.

Most people with recurrent pericarditis experience the same symptoms as they did with their first episode of pericarditis.
