A couple months back I was training with pads and one of my punches missed the pad by inches and slammed into a solid brick wall. At the time my knuckles swelled up really bad and my middle knuckle made a crunching sound (like walking on fresh snow). The bad part is I was to stupid to go to the doctor and I am going on vacation this week so no doctor right now. Now anytime I hit even a heavy bag my middle knuckle hurts. Anyone know what was/is wrong with my hand? Advice is wholeheartedly welcomed.
