Why does pain cause eyes to water?

Why when, for example, a hair is pulled from your nose, do your eyes tend to start watering?

Hobson's choice

If you are hit in the face by a cricket ball, would it be more painful at a distance of 50 centimetres from the thrower's hand, or 5 metres? To put it another way, at what point does the ball start decelerating?

Why does pulling out your nasal hairs make your eyes water in a way that a similar level of pain elsewhere on your body wouldn't?

Delayed pain response

Why, when I stub my toe or spill hot liquid on my skin, does the actual sensation of pain come a few millisecond after the realisation of what's happened.  Why do they not occur together?

When I cry, or am about to cry, I feel an achy physical pain behind my knee. What is the cause of this?

Sometimes I feel this ache in my shoulder as well. It is a strange phenomenon that I have never heard happening to anyone else.

Given that there are no pain receptors in the brain, how do we experience the pain of headaches and migraines?

I understand that there are no pain receptors in the brain, so people undergoing brain surgery can be alert, with anaesthetic administered only locally to the scalp.

If this is so, how do we experience the pain of headaches and migraines, especially those that seem to come from a specific point inside the head and which throb and radiate from that point?

Why does it hurt physically when you miss someone alot?

I have been going out with my girlfriend for a several months now.  We like to talk to each other on webcam when we are seperated for periods of time.  We both started discussing missing each other, and neither of us could work out why we both feel a physical pain in the region where our hearts are when we feel a deep feeling of missing each other.  Can anyone explain this phenomenon?
