I forgot to mention:
Most at risk for shingles:
Anyone who has already had chickenpox - Shingles is basically a second outbreak of the chickenpox virus. Since it is caused by a preexisting virus in the body, shingles is not contagious and can not cause other forms of herpes. It could, however, cause chickenpox in someone who hasn't had chickenpox before.
(I was worried about this because I have two children and my sister in law was pregnant at the first occurance)
A typical case of shingles lasts about a month. However, the pain associated with herpes zoster may continue for months or years in people who develop post-herpetic neuralgia (PHN).
(Post-herpetic neuralgia (PHN) The pain that lasts after the shingles rash is gone.)
