I punched a wall about 10 days ago and due to no health insurance i decided not to have it checked. Immediately following the punch i had intense pain and some swelling. I iced it immediately and wrapped it with an ace bandage after that. The swelling has been going away and there is very little pain. The pain i have is when i try to open my hand all the way. My pinky simply wont extend with the rest of my hand. I can make a fist with only a little discomfort, but it feels like my knuckle needs to pop. Also my knuckle is not pronounced anymore and i have a large knot behind where the knuckle was. Im guessing i broke the 5th metacarpal but from what ive read the pain would still be present. If i bruised the end of the bone could the bone swell and cause my symptoms?
