"In general, true pleurisy is an inflammation of the lining of the chest cavity — the pleura — and isn't self-limited (it doesn't go away with one painful breath," Minkin continued. "The other possibility to account for that type of pain is something called costochondritis, which is basically rib inflammation. When you press on the rib, it hurts. (It scares many women because they think it is actually breast pain!) All I can tell you is that it is pretty common. What I tell my patients, if it is very self-limited (like it lasts for one or two breaths), don't worry about it. If it persists, that evaluation should be done."
