The VAS and activities of daily living were used to evaluate pain intensity‐ and health‐related quality of life. VAS was measured on a scale from 0 to 10, where a line was about 10 cm. The two ends are the “0” end and the “10” end, where 0 indicates no pain, and 10 indicates the most severe pain. The activities of the daily living questionnaire were based on the Zoster Brief Pain Inventory questionnaire which was considered as a useful measure for quantifying herpes zoster pain, PHN, and impairment in daily living activities for clinical trials of herpes zoster prevention. The activities of the daily living questionnaire contain seven items including general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. Each question score referring to activities of daily living ranges from 0 to 10, where 0 indicates no interference and 10 indicates complete interference.
