 Cervicogenic headache originates from disorders of the neck, including the anatomical structures innervated by the cervical roots C1–C3.Cervical headache is often precipitated by neck movement and/or sustained awkward head positioning.It is often accompanied by restricted cervical range of motion, ipsilateral neck, shoulder, or arm pain of a rather vague non-radicular nature or, occasionally, arm pain of a radicular nature.
