Pleurisy or pleuritis is inflammation of the double membrane, or pleura, that lines the chest cavity and surrounds the lungs. This severe condition can reoccur even after treatment, so it is essential to contact a doctor when one experiences symptoms of pleurisy.
When the pleura becomes inflamed, the layers rub together, causing chest pain or pleuritic pain. The symptom usually starts suddenly and is described as a stabbing pain that gets worse with breathing but it can also be constant. Pleuretic pain is usually present only on one side of the chest, and the individual can often point to the exact location of the sensation.
