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