This thread got me wondering whether pain that different than many emotional complaints such as depression, anxiety or malaise? Or complaints such as fatigue. A significant majority of people may react to an “injury” in a certain manner, but a minority of folk maintain that they are profoundly impaired by their experience.
So perhaps, it might be possible to devise VERY general guides as to the expected reaction (pain or emotional) to certain injuries, while acknowledging some folk may have a greater or lesser reaction. For those folk who are towards the extreme, it might be valid to question the degree to which some other factor is contributing to their perception/claims. I also imagine that, as you approach those extremes, it might be more challenging to try to factor out physical versus mental/emotional bases for their descriptions.
