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.

For a nasty infected cut or in my worst case a nasty puncture wound from a rusty nail. Within about 6 hours I had a red streak going up my leg from the blood poisoning. My mother took an Irish potato and washed it, cut it in half and scraped out a pile of mushy raw potato. She put it on a piece of plastic bag to hold in the potato juice and wrapped it around my foot. The next morning the red streak was gone and my foot was healing with no sign of infection. Over the years I too have used this folk remedy on my family. Just make the potato poultice leave it juicy and use it inside bandaging for an infected wound. Plastic helps to keep it wet and keep you dry. Leave it on the wound overnight. Then take it off and examine the wound if it's still infected clean it off again and reapply the poultice. Somehow it draws the poison and infection out.
Mother nature is simply amazing!
