Hi Janie,
Welcome to the NeuroTalk Support Groups.
You may want to do a forum search, either for all forums or just for one specific forum, if you use the
Forum Search Feature
You could read and/or post over on the
Headache Forum
There are also some older posts regarding cervicogenic headaches in the
Spinal Disorders & Back Pain Forum
If cervicogenic headaches are caused by some type of cervical spine dysfunction, I'm very surprised the doctors haven't organized some physical therapy for you to work on the muscles and posture problems that you may have.
Hopefully others here will be able to suggest appropriate steps for you to take to eleviate your pain.
take care.
