Chronic pain management is complex. 27.2 to 43.5 % of general population suffers from it. Opoid crisis has shown the limit of the WHO 3 step analgesic ladder. Multidisciplinary pain management programs, shared decision making and non pharmacological interventions targeting subject's empowerment are needed. Among these non pharmacological interventions, patients are increasingly turning to traditional and complementary medicines. Evidence about their safety and efficacy is hard to build. Thus our study aims to assess the feasibility of a systematic proposal for non pharmacological interventions targeting the subject's empowerment.
