A subset develops postherpetic neuralgia marked by allodynia and hyperalgesia lasting months to years, with higher risk in older, immunosuppressed patients and those with comorbidities. Oral antivirals may lessen acute severity, yet prevention of neuralgia is limited.

It typically presents as painful grouped vesicles confined to one or two dermatomes. Most lesions resolve within two to four weeks; however, a subset of patients go on to develop postherpetic neuralgia in the area of the original zoster rash, characterized by allodynia and hyperalgesia lasting months or even years. The risk increases with age, immunosuppression, and underlying conditions such as cancer, kidney or liver disease, chronic lung disorders, etc. Although the use of oral antiviral medications during the early stages may reduce the severity and duration of acute herpes zoster, their effect on preventing postherpetic neuralgia remains limited. In this article, we report the case of a 75-year-old female with severe postherpetic neuralgia involving the left sciatic nerve distribution, with resulting motor paresis. After an extensive trial of various oral medication regimens and a lumbar epidural injection, which provided short-term relief, the patient underwent peripheral nerve stimulator (PNS) implantation, with eventual favorable response. Our case report highlights the potential role of using PNS to treat severe postherpetic neuralgia refractory to mainstay conservative treatment modalities.  \nCategories: Neurology, Physical Medicine & Rehabilitation, Pain Management  \nKeywords: atypical shingles presentation, chronic pain management, herpes zoster paresis, herpes zoster sciatica, peripheral nerve stimulator, postherpetic neuralgia, segmental paralysis associated with herpes zoster  \nIntroduction  \nPostherpetic neuralgia is a sequela following recovery from an acute outbreak of herpes zoster vesicular eruption. It is characterized by allodynia and hyperalgesia, most commonly between dermatomes T 1 and L2.  \nThe pain associated with postherpetic neuralgia can severely affect a person’s quality of life, and in extreme cases, can be debilitating [1] . Though herpes zoster generally affects the head, neck, and trunk, herpes zoster radiculopathy of the sacral segments can be particularly challenging to diagnose and treat, as it can overlap with other spinal pathologies. Currently, first-line management for this condition focuses on maximizing pharmacotherapy with tricyclic antidepressants, gabapentinoids, SNRIs, lidocaine patches, capsaicin topicals, and, if severe enough, opioids. Unfortunately, a subset of patients responds very poorly to the above-mentioned strategies. Several interventions have been documented in the literature, including subcutaneous Botulinum Toxin A injections, transcutaneous electrical nerve stimulation, local triamcinolone injections, intrathecal injections with methylprednisolone, stellate ganglion blocks, dorsal root ganglia destruction, pulsed radiofrequency, spinal cord stimulation, paravertebral blocks, and peripheral nerve stimulation [2] . Currently, there is no uniform consensus regarding the single best interventional treatment.
