I never had chicken pox as a kid so I know that I'm going to get slammed with them. My grandfather had them. It's not fun.
I'm happy to tell you that you won't get shingles if you didn't have chickenpox previously. Shingles is a reactivated version of the chickenpox virus, which lies dormant in the nervous system after chickenpox resolves.
