The foremost message that any pain physician should take from a chapter on neck pain is that neck pain and cervical radicular pain are not synonymous. The causes, mechanisms, investigations, and treatment of radicular pain differ from those of neck pain, and the two conditions have a different evidence base. Most emphatically, when a patient presents with just neck pain there is no justification for investigating and treating them as if they had radicular pain. Confusion in this regard has led to inappropriate investigations and therapeutic misadventure in the past and continues to do so. The topic of cervical radicular pain is covered elsewhere. The present chapter deals exclusively with neck pain.
