I got really mad and decided to punch a wall earlier today and hurt my right middle finger knuckle. A couple hours later I realized it not only bruised, but also started to swell and it got soft to touch, kind of like it was filled with fluid. I've iced if for a bit after I noticed the swelling and it's not as soft to touch anymore. I can still move my finger easily with mild pain (2/10) Should I be worried about a possible fracture? I've added some pictures if it helps.
