Hello, so I got into an argument today with my (ex) housemate, during this process I became enraged and proceeded to smash the outside of my right hand on the fridge, denting it in the process. He is now moved out but my hand is starting to swell and it hurts a lot when I press down on the bone.
Should I go get an x-ray?

Can you move your fingers? If so, I wouldn't be that concerned. X-rays are expensive, and knuckles breaks heal fairly easily anyways. I have many martial arts friends that break their knuckles on purpose by punching things, to make the knuckles stronger. Not that I agree with that.

Either way, just put ice on it, and don't use the hand.

I'm an EMT.

Sounds like something I would do, but yes I would get an x-ray. Guess it was better than hitting him, right? But maybe not now you're hurting.
