hmm, had something odd happen to me the other day. i was stretching and yawning at the same time when i felt a sharp pain in my lung. i started to take small shallow breathes because it hurt to breathe normally. as i bit the bullet and decided to inhale deeply it almost felt like part of my lung was lodged between two of my ribs. something feels bruised inside and it still kinda hurts to breathe. is it possible that part of my lung got pinched between two ribs? i wonder...
