I had shingles when I was 18. I am now 36 and have never had any side effects from it. My doctor gave me some cream, I can't remember what it was called, and also took some over the counter Lysine, a vitamin supplement. I had it on my side, just about where my bra is. I do remember how bad it hurt and itched. The treatment my doctor gave me worked and within a few days, it started to go away.
