What is Pleurisy?

Pleurisy is inflammation of the pleura, the thin lining that covers the lungs and lines the inside of the chest cavity. It causes a sharp, stabbing chest pain that typically worsens with breathing, coughing, or sneezing.

It's most often caused by a viral infection, though it can also result from bacterial infections, pneumonia, blood clots, or autoimmune conditions. Identifying and treating the underlying cause is key to resolving the pleurisy itself.
