Hi, I have the exact same thing. I got genital herpes, was diagnosed with it, and then over the years I have had outbreaks on different parts of my body. I've had it on my wrist, arm, hand, knee, calfs, buttocks, and of course the genital area.
I was not told it was zoster, but that it was hsv-2. I have tried to find more information about this because it seems to be an uncommon occurrence. It drives me crazy not knowing where it will show up next. And I hate having to bandage it up so much because it just takes longer to heal, and itches like mad, but I don't want anyone else to come in contact with it.
a visual diagnosis of zoster isn't adequate.
zoster also doesn't reoccur on this many body parts and this frequently. If you get any of these rashes again outside of the boxer short area as we call it, definitely follow up on them with a dermatologist for a better diagnosis.
do you know what your hsv2 igg results were specifically? ie hsv2 igg 8.2 or whatever they were?
