I did, but i convinced my parents to take me to a dermatologist to get me a prescription of Retin-A, which blew it completely away. Looking back, it was overkill actually. Retin-A is really effing strong stuff. The skin on my cheeks would dry out completely and crack and bleed because of it. My dear friend Gudrun has shingles, and yes, according to her they really hurt bad. I think you're correct about chicken pox becoming shingles, as they are both a result of immune system compromisation.
