Pleurisy - Overview

Is this topic for you?

This topic provides information about pleurisy, which usually results in chest pain. If you have chest pain that concerns you and that your doctor does not know about, see the topic Chest Problems.

What is pleurisy?

Pleurisy is swelling (inflammation) of the thin layers of tissue (pleura) covering the lungs and the chest wall.

The outer layer of the pleura camera.gif lines the inside of the chest wall, and the inner layer covers the lungs. The tiny space between the two layers is called the pleural cavity. This cavity normally contains a small amount of lubricating fluid that allows the two layers to slide over each other when you breathe.

When the pleura becomes inflamed, the layers rub together, causing chest pain. This is known as pleuritic pain.

Pleurisy is sometimes called pleuritis.

What causes pleurisy?

In young, healthy people, an infection of the lower respiratory system camera.gif by a virus or bacteria may cause pleurisy. Pleurisy usually lasts a few days to 2 weeks. In very rare cases, the virus or bacteria may spread and cause pleurisy in others.

Other causes of pleurisy include air leaking into the pleural cavity from a hole in a lung (pneumothorax), injury to the chest (such as a broken rib), tuberculosis or other infections, or a tumor in the pleura.

Other conditions may also cause pleurisy. These include rheumatoid arthritis, lupus, sickle cell crisis, pulmonary embolism, or pancreatitis. Pleurisy may also develop as a complication of heart surgery.

What are the symptoms?

The symptoms of pleurisy are chest pain and difficulty breathing. The chest pain usually starts suddenly. People often describe it as a stabbing pain, and it usually gets worse with breathing. The pain:

  • May always be present, but it usually gets worse when you breathe in. You may avoid breathing deeply to prevent the pain.
  • Usually is on only one side of the chest.
  • May extend to a shoulder or the belly.
  • Is usually worse when you cough, sneeze, or suddenly move.
  • May ease when you hold your breath or press on the painful area.
