question: PATIENT CAME INTO CLINIC, HE HURT HIS FINGER AROUND CHRISTMAS ON RUSTED BARB WIRE.  NOW, THREE WEEKS LATER, SEVERE SWELLING, NO FEVER NO STIFFNESS BUT NO FOREIGN OBJECT IN XRAY. PATIENT HAS NOT HAD TETANUS SHOT, AT THIS POINT HE IS PAST INCUBATION PERIOD, BUT WOULD YOU RECOMMEND GIVING THE SHOT AT THIS TIME? COMPLAINING OF A GREAT DEAL OF PAIN?
