Pain is such a relative idea. For some people a simple needle prick practically requires a trip to the hospital while for some it takes a piece of bone sticking out for them to start to be concerned... There have been many studies done on a person's pain threshold (the amount of discomfort it takes for a person to admit pain) and people vary a lot. Yet there seems to be one major factor in play. It is so easy for a person in a well-developed country to admit pain and seek treatment. Yet in many third-world countries where medical treatment is not readily available people are forced to ignore the pain and continue on as best they can.
