What is pleurisy?
If you ask most people, "What is pleurisy," most probably
couldn't tell you. They might know that pleurisy is a disease
of the lungs, but they wouldn't be able to explain what causes
it. Pleurisy is also called pleuritis.
Pleurisy is a disease caused by an infection in the lining,
or pleura, of the chest cavity around the lungs. When the
pleura become inflamed, breathing becomes difficult and even
painful. Pain caused by pleurisy can be exceptionally
troublesome and sharp.
There are several layers of pleura below the rib cage. One
layer overlies the lungs. Another layer is on the inner wall of
the chest. The layers of pleura rub together, which allow your
lungs to expand and contract without bumping the chest
wall.
When these pleura become inflamed, the lungs can't move
easily within the chest, which causes pain and discomfort.
