Jammed/sprained a couple fingers this morning. Knuckle joints where the fingers meet palm are swollen and sore as hell. Have virtually zero grip in that hand now and can't really do much with it.

So is it better to try to continually keep those fingers moving to try to keep them loose and work the soreness out, or would it be better to try to limit the movement as much as possible?

Also, ice or heat for a sprain?
