I had shingles in the late 80's, on the right side of head.
Doctor was concerned about my eye & ear.
It didn't bother me much. No lasting effects.
My youngest son had a terrible case on his stomach and into his back. He was young, the pediatrician had me take him to a dermatologist to be certain.
His case was painful, looked like angry cottage cheese.
They say you can get it again.
I think they are now covering the vaccine on Medicare, but I have not decided to get it.
