Re: Herpes zoster infection - recurrent symptoms response
Though recurrent Zoster is not that rare, it is usually at a different site and my experience is when someone gets recurrent tingling and a blistering rash it is nearly always Herpes simplex (which can occur anywhere on the body and usually recurs in the same place). Early treatment does seem to limit the rash, as does early treatment of Zoster.
Treatment of the first episode of shingles before a rash appears on the basis of dermatome pain, especially on the face (as well as considering giant cell arteritis, etc), is one of those clinical decisions but Acyclovir is pretty safe and not expensive.
