Herpes zoster causes significant morbidity on over 1 million Americans every year. Although the majority of herpes zoster pain will self-resolve within one week, a significant proportion of patients will develop postherpetic neuralgia (PHN), which is characterized by debilitating pain that persists more than three months after the initial symptoms. Nerve blocks have been previously studied as a method to control herpes zoster pain in outpatient pain clinics and inpatient settings. This study aims to investigate whether emergency department ultrasound guided nerve blocks can prevent PHN and effectively treat acute herpes zoster pain.
