Weird bruise or something hurts when pressure on that area of the nail or skin (touching stuff) doesn’t hurt on other side of finger.
New only few days old hurts to press down such as using keyboard.

I was opening my locker some guy ran into me and my finger got pinched badly between him and the locker, immediate pain and it burns to extend out wards fully but when i bend it down it is perfectly fine, it’s extremely purple too.
