How To Treat Numbness And Pain On Head Due To Fractured Skull?

MY BROTHER FELL DOWN/GOT JUMPED (NOT CLEAR WHICH ONE BECAUSE HE IS AN ALCOHOLIC) AND INJURED HIS HEAD AND FACE A FEW DAYS AGO. WE TOLD HIM TO GO TO THE EMERGENCY ROOM BUT HE REFUSED TO DO SO. HE WOKE UP THIS MORNING WITH PAIN AND NUMBNESS AROUND HIS HEAD AND DECIDED TO GO TO EMERGENCY ROOM. THE DOCTORS DIAGNOSED HIM WITH FRACTURED SKULL, AND IMMEDIATELY TRANSPORTED HIM TO ANOTHER HOSPITAL. DOES THIS MEAN HE MAY BE PARALYZE. I AM JUST SCARED AND WONDERING THE OUTCOME. PLEASE HELP
