medical mistakes. the e.r. waiting game came in at number 2. and at a shocking number 1, waking up during surgery. you go in, you go under. that's the way surgery is supposed to go. but it doesn't always happen that way. >> there was a pain. there was a pain that you cannot deal with. >> it just goes on and on and you're screaming inside your head. >> they're on the operating table, paralyzed, unable to move or speak. they feel every poke, every prod, every cut. >> i just kept praying to god, please just let me out. just let me out. let somebody know that this hurts so bad. >> their nightmare is called anesthesia awareness. under anesthesia your muscles are paralyzed and your brain is unconscious.
