If you ever had chicken pox, high stress can re-activate the dormant virus, and it reactivates as "shingles". There is a vaccine that came out a few years ago to suppress it from happening.
I think the vaccine is only covered by insurance (USA) for people over 50 in most cases. If you are lucky enough to have coverage, get the vaccine. Shingles as an otherwise healthy 42 year old was no picnic, I can't imagine how bad it must be for someone older or more immuno-compromised.
Had chicken pox in my 30s. Not good. The shingles vaccine isn’t expensive, thank heaven. It’s a quarter century later and my mom got shingles at about this age…
