In this article posted at massageadvancer.com notice what it tells us:
"Your brachial plexus is the nerve bundle that travels from your cervical (neck) vertebrae to your arms. When these nerves, which provide motor and sensory function to your arms, leave your spinal cord they pass though your neck and chest on their way to their destination. At the beginning of this journey your brachial plexus passes very close to your scalene muscles. The scalenes are muscles are that elevate your upper ribs during respiration and assist in neck movement."
The good news is that massage therapy is the answer. A custom neuromuscular massage is designed to relax those neck muscles so that the pressure is released from the brachial plexus and blood can flow freely through this area.
