Do I need to go to hospital or MAU or do I leave it?

[Brokenfingeragain]

Fairly certain I've broken my little finger at the top knuckle (it's very painful, swollen and heavily bruised and the mechanism of injury would create a break). Is this a tape it up at home type injury or needs checking one?

I'd go to minor injuries and get it checked and x-rayed

Definitely minor injuries. It may need to be put into the correct position for healing
