This type normally begins in the neck or the occipital part of the head. Then the pain moves onto the forehead and affects the ear and the side eye.
This pain is persistent and has different intensity. It is also called Cervicogenic headache. It is often mixed up with tension and migraine headache. The cause for this headache is a problem with the cervical spine or an irritation or damage to the first three cervical nerves exiting the spinal cord.
Women are more prone to this headache than men. About 15 to 20 percent of patients complaining from a side head pain are dealing with cervicogenic headaches.
