Think I've done something odd to middle finger - a couple of days ago there was a sharp pain (can't remember what I was doing!), and the knuckle has swollen a lot and is very bruised. I can bend it, so not convinced there's a break, but the finger looks a bit bent and is cracking a lot when I use it - it hurts when it cracks, but in the scheme of stressful life it's nothing major. I'm thinking that even if there is a crack in the bone, they're unlikely to do anything at A&E? Seems very trivial to spend the hours over there. Any advice from nurses/A&E staff?
