Quoted:
Wife got them literally on her 30th birthday.
Worst. Present. Ever.
She got them on her head, neck, upper back.
She was messed up for a couple weeks between the meds and the pain.
We both had chicken pox as kids - her case was VERY severe, mine was very weak.
My luck sucks, so I am expecting to get them on my balls or something.
Actually, being exposed to someone with chickenpox or shingles might help prevent your shingles by "re-vaccinating" you and increasing your immunity to the virus, thus helping keep future outbreaks in check.
One of the theories about the increase in shingles is that people aren't having as many kids, and thanks to the vaccine the kids they do have no longer get chickenpox so people aren't being re-exposed to the virus and their immunity to chickenpox slowly decreases, making them more susceptible to recurrent infections in the form of shingles.
