I was 35 when I had shingles on my torso. My dad had it at the same time. We had visited my mom in the hospital. Later we found out her hospital roommate had chicken pox. My dr said I was the youngest patient he ever had with shingles. So painful even wearing the softest t shirt.
I had it at 14 or 15 , can’t remember exactly.
Doc said at the time I was the youngest to ever get it.
( Ever ?, Or just that he had seen , I don’t know which )
It itched bad , was given some kind of medical cream , went away in about a week.
