Mrs. greedo had it many years ago, they gave her something for it, and it got better.
google it and see if the symptoms match yours.

That was my thought...
Very good call, greedo. Certainly way painful, but they usually wouldn't hospitalize you for it. A quick WebMD descrip: "Pleurisy, also called pleuritis, is an inflammation of the pleura, which is the moist, double-layered membrane that surrounds the lungs and lines the rib cage. The condition can make breathing extremely painful. Sometimes it is associated with another condition called pleural effusion, in which excess fluid fills the area between the membrane's layers."
I've had it a few times. VERY painful.
