A carcinogenic headache is a type of headache that originates from issues in the neck or cervical spine. It occurs when pain signals from the neck are referred to the head, leading to a headache.
Unlike other types of headaches, which might start in the head itself, cervicogenic headaches begin in the neck and can spread to the head.
