A preliminary prospective observational study of the effectiveness of high-concentration capsaicin cutaneous patch in the management of chronic post-surgical neuropathic pain.

Introduction: Chronic post-surgical neuropathic pain is difficult to treat. Topically applied analgesics provide an alternative to systemic therapy in localised neuropathic pain syndromes. The aim of this study was to prospectively assess whether 8% capsaicin is effective in surgically induced neuropathic pain.
