Pain is considered as a typically contemporary malaise, an opinion which motivated our theoretical investigation and permitted to identify the problem of otherness and solipsistic condition of modern subjectivity. The clinical cases of chronic physical pain served as a basis for studying the place of pain in the psychoanalytic theory and use the methodology of travelling through the Freudian discourse in an attempt to understand what pain is this pain, which is the main objective of this survey. The path begins in the late nineteenth century, when Freudian language was still related to medicine, and this period allows an important distinction between pain for medicine and pain for psychoanalysis, and continues to the final Freudian texts. The survey brought an impasse: how to think psychoanalytically a pain that is physical? The answer comes from the Freudian discourse that, aware of the problematic relationship between mind and body approaches physical pain and psychic pain. In addition to this, I could also discover an association between physical pain with melancholy and with the inhibition of functions of the ego - these associations serve as the basis for choosing certain clinical managements.
