Introduction: Herpes zoster is a common viral infection, which is frequently seen in elderly or immunocompromised patients. It usually presented with painful neuropathy. However, it can rarely manifest as motor weakness. An 82-year-old male presented with L2–L4 myotomal weakness two-week post shingles. Diagnosis was made based on only history taking and physical examination. Other possible differential diagnoses were rule out through imaging and blood tests at that time. The patient made good recovery through analgesia and physiotherapy. Postherpetic spinal segmental paralysis is a rare complication arising from shingles. There was no consensus on diagnostic criteria and the underlying pathophysiology is still poorly understood. The main treatment modality of this condition is intensive physiotherapy and pain management.
