What are the complications?

Most people do not have any long-term effects, but for
some people shingles can cause complications.

The long-term nerve pain that some people experience after shingles is
known as post-herpetic neuralgia (PHN). This can be a severe, unpleasant,
long-term nerve pain that is often described as burning, stabbing or
throbbing. This can last weeks, months or for a few people, even years.

For some people even a slight breeze against the skin can be painful and
distressing. PHN can affect quality of life and the majority of sufferers say
they have less enjoyment of life and find their sleep, work and social life
disrupted. The older you are, the more likely you are to have long-lasting
nerve pain.

Sometimes shingles can develop in the eye and/or affect the skin of the
eyelid. This can cause severe pain and lead to decreased vision or, rarely,
permanent blindness in the affected eye.

Shingles can also lead to other complications like scarring, skin infections or,
rarely, hearing loss.
