Radicular pain from irritation of a nerve root in the cervical spine is associated with paresthesia, numbness or weakness in the dermatomal distribution. The combination of shoulder pain and neck pathology is not uncommon. •Herniated C4-C5 bulge: motor function: C5 shoulder abduction, C5 elbow flexion. Deltoid C5, biceps C5. Sensory C5. Biceps reflex is primarily C5. •Herniated disc C5-C6 bulge: motor function: C6 elbow flexion, C6 wrist extension (extensor carpi radialis longus and brevis), biceps C6, wrist extensors C6. Sensory: thumb and radial hand. C6 brachioradialis reflex. •Herniated disc C6-C7 bulge: C7 elbow extension,
