I had shingles and it was about a year after my husband died unexpectedly. Was in a pretty, dark place, not taking care of myself. Abusing myself really with alcohol and overworking a LOT to occupy my mind...not sleeping or eating right. Sound like a recipe for lowered immune system? Does to me. I had a mild case. Thought it was poison ivy. Fortunately my bi-annual check up was 2 weeks after it started up and I showed my doctor. She said, OH, that’s a classic case of shingles. Asked what to do she said Vitamin C and try not to scratch it lol!!
