I was walking rather quickly and hit my pinky on part of the cash register at work. It hurt REALLY bad right away. I put ice on it. Under the knuckle is swollen. This was 9:30am. By dinner time under the pinky on the hand was swollen and discolored. The next morning the knuckle is begining to turn pupleish tint. It is sore certain way I try to move it. I can move in. It hurts to try and make a tight fist orto put it right up againt he ring finger. The way I hurt it seems impossibke to have a serious injury to me. Do you think after time it will heal itself?
