oh yes with out it your finger could get infected
struck top of hand hard enough to break skin. fingers cold and numb. pain several hours after injury. worth x-ray? . hit my hand very hard on the rigid side of a couch. i have only ever broken a toe in my life so i don't know if i might have a fracture. i am in a fair amount of pain. pain increases exponentially if i try to move my fingers. worth the hour drive to the er for an x-ray?
