well I have posted here before about my knuckles broken, I was waiting for it to heal but that took too long but then I found how to heal quicker I drank MILK, and that actually healed my knuckle, so now I do Knuckle push-ups and my knuckles are really strengthining Try that, I can't find any other way to heal except for waiting ..or drinking the almighty MILK , oh and do Knuckle Push ups on a hard surface like wooden floors or marble.
