I had surgery a couple of years ago - rotator cuff repair. When I came to I felt like a loser and I had wasted health care dollars. Those thoughts weren't in my mind when I was put under, so I can only assume that this was said during the surgery.
It took me awhile to shake those feelings - I may have been finally pain free, but depression set in during the recovery period.
Since then, I have been very careful on what I've said when treating an unconscious patient.
