In reply to Marc (Jacksonville, Fl) on 02/04/2009: "possible blood poisoning. I scratched my arm with a piece of metal about a week ago. Now in that area it is swollen and red. I have my tetanus shot, what will bring the swelling down, and heal my arm?"
The first thing that comes to my mind is a bentonite clay poultice. mix up some clay and glob it on and let it dry. if you get red stripes on your arm or it continues to hurt and stay red go to the ER.
