I'd like to nominate my mother for the stubborn award. A few years back, when at my brother's house, she tripped coming out of the door. So she just sat there saying she was fine - don't worry about her. They kept asking if she was ok and she said she was. Finally she needed to use the bathroom but was unable to stand - so she was willing to crawl to the bathroom. That's when they called an ambulance (while she protested).

She had broken her hip and required hip replacement surgery.
