Cervicogenic. Cervicogenic headaches originate from disorders of the neck, including the anatomical structures innervated by the cervical roots c1–c3. Cervical headache is often precipitated by neck movement and/or sustained awkward head positioning. There are many things that can be done including, physical therapy, medications and injections.
Stretching. Try gentle stretching exercises and heat. Osteopathic manipulation therapy may be helpful.
