Postherpetic neuralgia (PHN) is also accepted to be associated with sympathetic system activation. While sympathetic blocks were utilized for upper\u2010extremity or face\u2010related PHN, there has not been any report regarding lower\u2010extremity PHN, as it is an uncommon region. Here, we present two cases of systemic drug\u2010resistant PHN in lower limb, relieved with lumbar sympathetic block. Both patients had at least 50% reduction in numeric rating scale (NRS) scores at the end of 6\u00a0months. Lumbar sympathetic block could be considered in the treatment of lower\u2010limb PHN. More reports and controlled trials are needed for further understanding the role of the intervention in this neuropathic pain syndrome.<\/jats:p>","DOI":"10.1111\/papr.12958","type":"journal-article","created":{"date-parts":[[2020,10,8]],"date-time":"2020-10-08T18:26:46Z","timestamp":1602181606000},"page":"353-356","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Lumbar
