hey how's it going guys?

a couple months ago i was pretty drunk, got mad, and wound up punching straight through two walls with my right hand.. needless to say the next morning i couldnt move my hand and i realized how bad of an idea that was.

but now, at least 5/6 months later, whenever i try to hit the bag at the gym, after about 10 minutes my right pinky knuckle and my thumb knuckle starts to hurt, bruise, and swell up pretty bad. i had gotten them x-rayed and according the hospital they weren't fractured or anything.. just 'internally bruised'.

my question was if anyone knew any way to completely heal my hand up? one of my dad's friends told me that when he used to box he knew a guy that said if you soak your hand in vinegar for 20 minutes a day your hand will become like stone.. i don't know how true that one is, but any ideas?
