How do I know if my finger is broken/cracked/bruised?

Sunny Sim Asked: How do I know if my finger is broken/cracked/bruised?

So during my football practice, I was trying to get someones flag, she passed my
fingers. I felt immediate pain and when I looked my top of my finger
(I am double jointed) and it was bent side ways. Afterward I looked at it and half of
my finger was purple ish/ blue ish color, and is swollen a lot. The pain did decrease,
but I can't move my finger without feeling pain. Around where my finger where it has
been bent there are blue bruises around it. Afterward I got acupuncture on my finger so
I don't know if that is causingthe bruises. Please tell me if I broke/cracked/or just
bruised it. I did put ice on it, but I don't think it got any better. I have flute audition on
Nov. 30 and do you think I am going to make it? And I have a game on Friday,
but do you think it is okay for me to still play?
(I am a corner back; and a girl if it is going to help) Thank you!
