Familiarization: Head received its sensation from upper cervical nerves. They starts in upper neck and travels under the neck muscles to the entire head. The pain usually radiates between upper neck to the top of head and sometimes to the eyes. This pain is not only caused by the cervical nerve but also caused by the joints, muscles and the discs.

Differentiation:

Migraine is usually a throbbing and aching pain on the one side of head and usually accompanied by aura (before migraine pain starts there may be symptoms like heaviness of head, double vision, vomiting, giddiness etc) whereas Cervicogenic headache is a typical pain starts at the back of the neck and referred to the head and eyes.
