Out of curiosity, I wonder: - What about similar observances when person is standing? - Or if cancer pulls and creates creases? - Or, while patient goes to stand up listen to hear if movement down through bowels? - Or of trying to sit or get up causes pain anywhere? - - Why? In order to include notes for possible internal pinches or creases caused by cancerous growth or other blockage that are less evident when patient is prone. After all people often stand or sit for the majority of their day.
