Answer

PHN is the most common complication, affecting as many as 50% of patients older than 60 years. It may develop as a continuation of the pain that accompanies acute zoster, or it may develop after apparent resolution of the initial zoster reactivation. The pain may last for months to years. [5] The underlying pathophysiology of PHN may involve peripheral nerve damage or continued viral activity.
