Why do I faint and have a low pain tolerance?

If I get hurt really sharply or suddenly, I end up passing out. This has happened once when I slammed my finger in a doorway, once when I bashed my elbow on the shower wall, once when my finger was held in an awkward, painful position, and once when I got a flu shot. Why do I pass out like this, and why do I have such low pain tolerance?

Is it important to have a primary health care provider?

I've been hearing a lot about having one health care provider follow my medical history, but I'm fairly healthy and don't have a chronic disease. I've been switching from my local doctors when I'm home to the on-campus docs. Is it really that important, given that I'm a healthy individual?


What should I do about my girlfriend's ex-boyfriend who won't go away?

What should I do about my girlfriend's ex-boyfriend? Their friendship is getting out of hand. He is consistently telling her how regretful it is for him and he wants her back badly. He would go out of his way to see and to talk to her. This is affecting my relationship. It is affecting my girlfriend emotionally. This has been going on for four years. I met my girlfriend two years after their break up. He is now more persistent than ever.
