Should I be worried or not bruised fingertip

So I slammed my closet door pretty hard onto my finger yesterday on accident it swelled up and became this bruise I can still feel with the finger I think - some arm discomfort too when moving but I probably slept on it wrong when should I start to worry if that was the case since I’m not. A health care professional or anything I don’t know when it’s bad enough I’ve probably posted this on the wrong topic since I didn’t know if this would be tmi or not sorry ! So tmi warning
