Here is an interesting article I found on people's perception of pain. The money quote:
Many researchers are therefore concluding that genetics underpins at least some of the difference, and that females really do feel pain more than males.
In my experience a lot of women seem to think that female pain tolerance is higher than males'. That has now been scientifically disproven. Take that.
Another section that was personally interesting to me because I suffer from migraines:
The latest example of such a difference is in migraine, a condition that is three times more common in women than in men. In 2004, a group of researchers led by Michel Ferrari of Leiden University in the Netherlands reported that they had created what they believed to be the first mouse model of migraine. Since some researchers argue that migraine is associated with heightened sensitivity to pain, they sent their creation to Dr Mogil for testing. He stresses that his data are preliminary. However, he does find a lowered pain threshold in the mouse migraine model compared with healthy mice—but only in females.
Since I suffer from migraines does that mean I have a low pain threshold and feel pain like a girl? (And in this case I do mean that in the pejorative sense.) Anyway, read the whole thing, but keep in mind there will be a lot of scientific mumbo-jumbo (like mu and kappa-opioid agonist).
