Pleurisy

You have pain in your chest. Your healthcare provider has told you that you have pleurisy (pleuritis). Pleurisy is swelling (inflammation), irritation, or infection of the pleura. The pleura are 2 layers of thin, smooth tissue that surround the lungs and line your chest wall.

Pleurisy occurs when inflammation affects the pleura. Normally, there is a small amount of fluid in between the pleura. This fluid helps the pleura move smoothly past each other when you breathe in and out. But when you have pleurisy, the swollen pleura rub against each other when you breathe. This is very painful.

Pleurisy is inflammation of the pleura. The pleura cover the lungs and line the chest.

What are the symptoms of pleurisy?

Pleurisy often causes sudden sharp and stabbing chest pain. Sometimes the pain may become a constant dull ache. It's often worse when you take a deep breath, cough, or sneeze. Shortness of breath is also common. Based on the cause of pleurisy, you may also have fever, unexplained weight loss, and body aches.
