Objective To evaluate the influence of food supplements with fatty acid omega 3 on the remission of a neurogenic inflammation denoted as centrally mediated chronic myalgia. Methods 24 patients were selected between the ages of 19 and 42, divided into the Experimental Group (n = 12) and the Control Group (n = 12). The patients were evaluated for spontaneous and provoked pain, respectively, by means of a visual analog scale and palpation of the temporal and masseter muscles; they were also evaluated by means of pressure algometry in order to check muscular sensitivity. The data were recorded at T0 (start), T7 (seven days), T14 (fourteen days), T21 (21 days) and T28 (28 days) after the application of the methodology. The patients in the Experimental Group, simultaneously with the use of the neuromuscular myorelaxant splint, were supplied with 1 g of fish oil capsules, three times a day. The Control Group used only the neuromuscular myorelaxant. In order to monitor the omega 6 / omega 3 ratio, blood collections were performed in the Experimental Group, prior to therapy and again after using the supplement for 28 days. The analysis of the fatty acids was conducted using gas chromatography. Results The results demonstrated an improvement in pain in both groups, there being a significant statistical difference between them only for the evaluation via Pressure Algometry. The ingestion of omega 3 was effective for obtaining a better proportion of omega 6 and omega 3 and with the reduction in pro-inflammatory cytokines. Conclusion The anti-inflammatory potential of fatty acid omega 3 and also the effectiveness with pain remission was confirmed.
