In this paper we analyze the contexts of vulnerability involved in the formation of the phenomenon of chronic pain without organic cause, or fibromyalgia (DC/FM). A key factor that articulates the contexts of vulnerability and subjectivities that they produce are gender rela-tions, we characterize two (traditional and transitional) models. The research from which we derive the data is qualitative by semi-structured interviews, in the context of metropolitan Barcelona (Spain). From the analysis we have made a close relationship between the devel-opment of the DC/FM and social models of gender, both in the context of constitution of subjectivity of the interviewees, child life, and in the context of occurrence follows and development of the DC/FM in adulthood
