I popped my finger against someones chest while playing football yesterday and then again shortly after on someones foot. Now my finger is swollen and the middle joint is blue. I can move the finger in both joins except for the blue one. Moving this joint hurts and I can't move it very far. Also, the finger appears to bend to the left very slightly. Is this a dislocation, broken finger, or just a pop and what should I do to it?
