Hand and arm discomfort and numbness are frequently associated and diagnose as a cervical disk. However, this isn't always true. Numbness, tingling, and other odd sensations are among the symptoms of myofascial pain syndrome produced by muscle tension. The nerves that supply the arms and hands (Brachial Plexus) pass through the gaps between the cervical vertebrae and various muscles, and tension in the neck muscles compresses the nerves, causing symptoms similar to a disc, such as numbness, pain, and sensory abnormalities in the arms and hands. In general, a forward-bent head leads the back to bend and the chest muscles to shorten, compressing the nerves and blood vessels.
