I feel for you man, what ever the circumstances i bet you regret it know, Hind sights a bitch

I busted my hand pretty good about 9-10 months ago, i was out drinking with some friends, one of which convinced me to punch a wall ( belive me i know how retarded it sounds

) but any way woke up next morning my knuckle all bloody and swollen but decided against hospital ( hate those places ), i know it was a bad decision but i firmed it and it did not heal for about 3 months!, luckily no infection and i can move it fully again now but i imagine if a doctor had taken a look and bound it up the right way it would have healed in 1/2 the time. ( im no doctor but i think it was borken or something, i now have a reshaped larger knuckle

lol )
I am pretty confident that if you want it healed properly a fast as possible ( and you dont want to go to the hospital ) then your best bet is not use your bad hand for anything ( as little as possible ) and every day slowly stretch it to keep it from seizing up. Hand Injurys vary so much i can only say what helped me. The last 2 weeks before my hand was actually better i straped my hand up so it could heal properly, i found this helped for me alot an added bonus was that you find you cant use your bad hand for anything so it really does give it time to heal.
