Can you give me advice with headache and severe pain in back of neck!?

Cervicogenic HA: Is a very common headache secondary to neck involvement. Cervicogenic headache is a unilateral pain provoked by neck movement or by pressure on the neck. These headache patients usually had a reduced cervical range of motion in association with the headache that was often radiated in the orbital and frontal areas. Rec.: see orofacial pain or headache specialist for evaluation and treatment.
