About 5 days ago this hard ball like knot
under th skin appeared (again, but normally goes away after a few) but this time was rather larger. Day 1 I left it alone , dAy 2 became lArger and a bit more painful. I thin sterilized A safety pin an gave a few pokes an a cpl squeezes. Nothing but clear came out, a few hours same, but with a lightish blood. Next day was worse, golfball size and now sore. Still using th sterile pin, picking to about marble size hole.
