An inflammation of the serous membranes that both surround the lungs and line the inside of the chest cavity; the two membranes supply fluid lubrication between the expanding and contracting lungs and the body. Most pleurisy (and usually the milder form) follows or accompanies bronchitis or late winter chest colds...sort of pulmonary cabin fever. It may be dry pleurisy (with few secretions and sharp sticking pain that prevents any but moderate inhalation), or acute or effusive pleurisy (with fever, coughing, and built up serous fluids...usually tossed off as bronchitis). Some types are part of serious cardio-pulmonary disorders and/or chronic disease.
