 Objectives:To study the pathway of scapula and upper chest pain (referred pain). Materials and Methods:Patients who had cervical radicular pain and were treated with NSAIDs for at least 2 weeks were performed the interscalene brachial plexus block (IBPB). The intensities of radicular and referred pain were measured using visual analog scale (VAS). Results:The average VAS scores for radicular pain with or without referred pain were significantly reduced by the IBPB at 5 minutes and 7 days after the injection. The referred pain was significantly reduced in the patients with stellate ganglion block (SGB) effect than those without SGB effect. Conclusions:The referred pain pathway was likely interrupted by IBPB with the side effect of SGB. The main afferent fibers of the cervical related pain pathway were thought to involve the T1 and/or T2 spinal nerve,presumably via sympathetic afferents.
