You have pain in your chest. Your healthcare provider has told you that you have pleurisy, or pleuritis. Pleurisy is swelling (inflammation) of the pleura. The pleura are two layers of thin smooth tissue that surround the lungs and line the chest.

What are the symptoms of pleurisy?

Front view of man's neck and chest showing right lung covered by normal pleura. Left lung is covered by inflamed pleura.

Pleurisy usually causes sharp chest pain. It is usually worse when you take a deep breath, cough, or sneeze.

What causes pleurisy?

Many things can cause pleurisy. A common cause is a viral infection like the flu or pneumonia. Serious lung problems that can cause it include:

  • A blood clot in the lung (pulmonary embolism)

  • Air between the pleura (pneumothorax)

Serious heart problems that can cause pleurisy include:

  • Heart attack

  • Inflammation of the covering of the heart (pericarditis)

How is pleurisy diagnosed?

Your healthcare provider examines you and asks you about your symptoms and health history. He or she will first check you for the serious causes of chest pain. You may have:

  • Lab tests

  • Imaging tests such as chest X-ray, CT scan, or ultrasound

  • ECG

How is pleurisy treated?

Treatment depends on what is causing the pleurisy. Serious conditions are treated in the hospital. You may need medicines to decrease the inflammation and pain.
