This invention relates to a method for the biochemical treatment of persistent pain disorders by inhibiting the biochemical mediators of inflammation in a subject comprising administering to said subject any one of several combinations of components that are inhibitors of biochemical mediators of inflammation. Said process for biochemical treatment of persistent pain disorders is based on Sota Omoigui's Law, which states: ‘The origin of all pain is inflammation and the inflammatory response’. Sota Omoigui's Law of Pain unifies all pain syndromes as sharing a common origin of inflammation and the inflammatory response. The various biochemical mediators of inflammation are present in differing amounts in all pain syndromes and are responsible for the pain experience. Classification and treatment of pain syndromes should depend on the complex inflammatory profile. A variety of mediators are generated by tissue injury and inflammation. These include substances produced by damaged tissue, substances of vascular origin as well as substances released by nerve fibers themselves, sympathetic fibers and various immune cells. Biochemical mediators of inflammation that are targeted for inhibition include but are not limited to: prostaglandin, nitric oxide, tumor necrosis factor alpha, interleukin 1-alpha, interleukin 1-beta, interleukin-4, Interleukin-6 and interleukin-8, histamine and serotonin, substance P, Matrix Metallo-Proteinase, calcitonin gene-related peptide, vasoactive intestinal peptide as well as the potent inflammatory mediator peptide proteins neurokinin A, bradykinin, kallidin and T-kinin.
