Got into a fight Monday night. Immediately afterward I could tell my hand was not in the greatest of shape. Couldn't move 3 of my fingers without pain... Iced it for 20 mins before wrapping it up. Got sent to by the gf to Solantic where they said I fractured my knuckle. This was monday night. They put a splint on it. Well Yesterday I took the splint off because my hand was feeling better. Have had it wrapped on and off since then. I can completely close my fist and use it like normal with minimal pain. I'm supposed to get a cast put on my hand tomorrow morning, I think its overkill.
So my question is this, if I can continue using my hand like normal (like I'm doing right now), is it really broken? Obviously I'm not in fighting shape but I figure my hand will heal. Is a cast really necessary?
