Approximately 10% of affected individuals will exhibit no prodromal pain.
Conversely, on occasion there may be recurrence in the absence of vesiculation of the skin or mucosa.
This pattern is called zoster sine herpete (zoster without rash), and affected patients have severe pain of abrupt onset and hyperesthesia over a specifi c dermatome. Fever, headache, myalgia, and lymphadenopathy may or may not accompany the recurrence.
