It usually affects a specific area on either the left or the right side of the body.
There are three main stages, first, pain is felt in a localised area of the head, back or side, then a rash, blisters and flu-like symptoms occur, finally, blisters erupt and pain increases which can lead to Post-Herpetic Neuralga.

If treatment is started within the first three days there is a lower chance of complications such as post herpetic neuralgic pain.

It is so important to recognise the symptoms and produce a comprehensive plan of care for the resident or patient.
