Headache and neck

Abstract

Cervicogenic headache (CEH) is currently identified with different diagnostic criteria. The latest one is the International classification of headache disorders (ICHD), 3rd edition (2018). At the present time, there are not enough published articles with reliable sensitivity and specificity that may support a classification for clinical and research purposes. Current literature suggests improvement to the classification(s). The ICHD criteria should be modified to reach an optimal sensitive and specific level to identify CEH as a secondary headache. The B, C1, and C2 criteria should be implemented with proposed suggestions. The C3 criterion should be upgraded. Criteria such as mechanical precipitation of pain by digital pressure on neck trigger points and specific movements, strictly unilateral pain without side-shift, diffuse unilateral shoulder and arm pain, pain starting posteriorly and spreading anteriorly should be integral part of the classification.
