The classic triad—ipsilateral facial weakness, severe otalgia, and clusters of vesicles on the ear or canal—emerges within days of reactivation. When the rash is absent (zoster sine herpete), the diagnosis rests on the facial palsy plus otalgia and a positive PCR for VZV from a skin‐scrape. Ancillary findings include: - Hyperacusis (stapedius muscle paralysis) - Decreased lacrimation (greater petrosal nerve involvement) - Dysgeusia on the anterior two‑thirds of the tongue (chorda tympani) - Sensorineural hearing loss or vertigo from cochlear/vestibular nerve irritation. Clinical trajectory check Link new findings to the underlying process and the compensatory response that is succeeding or failing. Reassess objective trends such as perfusion, oxygenation, mental status, pain pattern, labs, and response to time-limited interventions so the next action reflects improvement or deterioration rather than a memorized label.
