Hey Jay,
I'm not a doctor and I don't play one on TV either but I would bet that
you have an infection and not merely an immune response to an antigen.
Both can produce inflammation but the production of puss (lots of white
blood cells called up to fight an infection) is more likely due to
bacteria. Get to a doc, even a small puncture wound like a splinter
can introduce anaerobic bacteria - like the ones that cause gangrene.

I'm not sure if it's Doug Fir or Hemlock that's in there, but I've got
a splinter that's really putting out the puss. And the thing is, I
thought I got the whole thing out. Are there certain species that are
more splinterific than others?
