Why does it hurt to get your nose pierces?

A nose piercing does not hurt as bad as most people expect. I got mine pierced two days ago and was a little nervous to get it. When the needle went through it was more like a quick pressure. It did not hurt at all compared to what I made it up to be. Of coarse it will be sore after though. And piercing especially to the face is trauma which will become sore. The soreness will go away in a few days
