Pain is a concept familiar to all of us regardless of our background, stature or standing. Its almost like a drug, we can't live with or without it. We subconsciously crave it when we don't feel it, and go well out of our way to remedy it when it takes us over.
I came across this interesting article on The Economist : Pain Perception - Sex and drugs, which highlighted some interesting aspects on how men and women perceive pain differently.

One thing still stands... men are a lot less vocal about expressing pain (both physical and emotional) than women are. Although it makes understanding men's problem for women a lot more difficult, it might coincide with their lack of expectation of someone being able to relate to their pain!
