I got kinda angry. Long story short, I punched a wall and their area between my 2nd and 3rd knuckles is swollen.
Doesn't hurt much. Kinda spongy but tough to touch. What should I do apart from not punching walls anymore, and is it broken?
There is no way to tell if you have broken a bone or two in your hand from punching the wall unless you go and get a x-ray. In the mean time you should ice your hand to help reduce the swelling. Ice it for at least 30 minutes a couple of times a day.
