I don't want to just blithely call this a Herx, but most likely you have
pathogens fleeing the onslaught of the Lipo-C and going to the skin to try
to survive. My very first experience with such a thing was from my first few
doses of CS, made from Ode's Silverpuppy, back in early 2000. Since then
I've become an old hand at it. It is often aggravating, sometimes disgusting
and never any fun.
