Pleurisy is a condition in which the pleura — a membrane consisting of a layer of tissue that lines the inner side of the chest cavity and a layer of tissue that surrounds the lungs — becomes inflamed. Also called pleuritis, pleurisy causes sharp chest pain (pleuritic pain) that worsens during breathing.

A variety of underlying conditions can cause pleurisy. Treatment of pleurisy involves pain control and treating the underlying condition.
