ObjectiveTo describe a series of older adult patients with postherpetic myofascial pain, a heretofore rarely described complication of herpes zoster.DesignCase series.SettingOutpatient older adult pain clinic.PatientsFive older adults are presented with myofascial pain that developed as a complication of herpes zoster.ResultsPain duration at the time of presentation ranged from 4 months to 7 years. All patients reported functional impairment from pain despite oral analgesics. Myofascial pathology was diagnosed by the presence of taut bands and trigger points in the affected myotome. Upon successful treatment of the myofascial pain with nonpharmacologic modalities (e.g., physical therapy, trigger point injections, dry needling, and/or percutaneous electrical nerve stimulation), all patients reported symptomatic improvement, and four out of five were able to significantly reduce or discontinue their opioids.ConclusionPostherpetic pain is traditionally conceptualized as a purely sensory phenomenon. Identification of the intrusion of a myofascial component may be worthwhile, both from the standpoint of enhanced pain relief and reduction in the need for oral analgesics. Formal exploration of this phenomenon is needed.
