One of my grandmothers had shingles in her 70s, and, though I was a child at the time, recall her moaning with pain.
Fast forward several decades to the day I watched my five-year-old granddaughter suffer the miseries of shingles. The doctor said her exposure to a child with chicken pox caused the attack of shingles because her own case of chicken pox a year earlier had been very light. (The virus that causes chicken pox may be reactivated as shingles in the young, old or anyone with poor immune systems.) Most people don't realize that children and adults can get shingles from exposure to chicken pox.
An even worse fact about shingles is that the virus hibernates in the sufferer's nervous system and can reoccur. I don't know if the shingles vaccine will help you at this point, Elayne, but you may want to ask your doctor if it will prevent reoccurrence. Older people are encouraged to be vaccinated against this painful virus, and I've already done so.
