Most people do not have any
long-term effects, but for some
shingles can cause complications.
The long-term pain that some people experience after shingles is known
as post-herpetic neuralgia (PHN). This is a severe, unpleasant, long-term
nerve pain that is often described as burning, stabbing or throbbing.
PHN can prevent sufferers from living a normal life, and for some even a
slight breeze against the skin can be painful and distressing.
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
even permanent blindness in that eye. Shingles can also lead to other
complications like scarring, skin infections, or permanent hearing loss on
the side of the body where the rash developed.
