Pleurisy lasts anywhere from a few days to two weeks in most cases, according to WebMD. The exact amount of time an episode lasts depends on various factors, such as the underlying condition causing the pleurisy.
Pleurisy, an inflammation of certain tissues that are adjacent to your lungs, is almost always caused by another condition. Some of the primary causes of pleurisy include the flu, rheumatoid arthritis, fungal infections and bacterial infections, according to the Mayo Clinic. The main symptoms of pleurisy are chest pain when breathing and shortness of breath. Less frequently seen symptoms are coughing and a fever.
