4. Protection Against PHN
Shingles is not merely annoying, but it can lead to a more serious condition known as PHN. For most people, the symptoms of shingles pass with the fading of the rash, but for 10% of shingles sufferers, the problem develops into PHN, which is longer-lasting and is more extreme.
PHN occurs when the shingles virus hits the nerves and it can cause intense feelings of depression as well as eye problems if the optical nerve is affected.
Even though most shingles sufferers don’t experience PHN, the illness is sufficiently severe to make a shingles vaccine a good idea.
