Here is a video to explain what Cervicogenic Headache is. The International Classification of Headache Disorders, considers Cervicogenic Headache to be a secondary headache disorder. This means that the head pain and symptoms, originate from somewhere other than the head. In this case, dysfunctional structures in the neck, such as; muscles, joints, discs or even nerves can be the cause of headache. Through afferent nerves from the neck to the brainstem, these structures can create pain pathways to the head and face. https://brisbanemigraine.com.au/cervi...
