Complex regional pain syndrome is a painful syndrome often secondary to a traumatic lesion. Treatment is difficult, of long duration with variable outcomes. Patch of capsaïcin has been proposed as adjuvant to a multimodal treatment. Capsaïcin may act by its effect on transient receptor potential vanilloid 1. Efficacity and outcome studies with this treatment are lacking. The aim of this retrospective study is to evaluate pain intensity over time assessed by visual analog scale in patient with complex regional pain syndrome treated with capsaïcin patch in addition to their usual treatment.
