Question

What is pleurisy and how do you get it?

Answer 1

When we breathe, the thin tissues lining the lungs and chest wall, known as the pleura, rub against each other.

Usually this is not a problem, as they are satiny and generate no friction at all.

But, if there is an inflammation around these tissues or infection then it becomes irritated and swollen, causing a lot of pain. This condition is pleurisy.
