That is super weird. I know once you've had chicken pox, then the virus is always in your system. But it's more rare to get shingles that young after a natural chicken pox infection in childhood compared to the chicken pox vaccine. Shingles is super contagious. I'd guess you were around someone with an active infection, or your immune system is compromised or stressed. But I'm not a doctor and all that.
