My left hand's fourth finger tip hurts when pressed on something a little. It came from basketball, I thought it was jammed at first but I can move it just fine without pressure on it. It isn't swollen and there aren't and visible bruises. I can still dribble lightly, but it hurts if I do something like flip on the light switch with it. Thanks!

After close exam, ( OK, get the hint, we can't even see it) and to really know it would need to be looked at by a health care professional.

But yes it sounds jammed
