I was mid 40's when I had a bout on my hip...AVEENO anti-itch cream was a life saver...it stops a lot of the pain and itch. It's main purpose was chicken pox itching relief.
When I had it there was no itch or pain at the site of the rash, just a rash. The pain radiated along a nerve from my stomach in a circular pattern to my shoulder then up my neck. It was intense and lasted several weeks.
I felt fortunate because the doc told me that for some people it lasts for months and even years.
