Shingles is an acute, unilateral, self limiting painful blistering rash caused by reactivation of the Varicella Zoster Virus (VZV) – the chicken pox virus
Prodromal symptoms are:
- pain along affected dermatome
Zoster Sine Herpete – this is rare, it’s where the nerve pain but no rash.
The classic rash is the grouped vesicles on a red base in a unilateral dermatomal distribution – these begin as red macules and papules and over 7-10days, become vesicles then form pustules and crust. It takes about 4 weeks for complete healing.
You can’t catch shingles from someone with chickenpox or shingles, but you can catch chickenpox from someone with shingles if you haven’t had it before.
