What is up with my skin?

I thought I had mild "papulopustular rosacea." Putting Polysporin on the red bumps helped a lot. Then I took acyclovir for a cold sore and the bumps cleared up completely! None of the online resources on rosacea have indicated acyclovir as a treatment. So what did I have? [more inside]
