Pleurisy is an inflammation of the pleura, the membrane which covers the lungs and lines the chest cavity. This membrane, when inflamed, goes through the regular inflammatory changes—first a dry or congested stage, followed by an effusion of serum from the blood. Causes.—The causes are similar to those of bronchitis and pneu- monia, especially colds from exposure, etc. ; but it may occur in con- nection with other diseases, as rheumatism, influenza, etc. It is also seen as a result of various injuries of the chest—kicks, punctured wounds, blows, etc. Symptoms.—Pleurisy comes on suddenly, usually with a chill.
