Boydo,

Have you had any diagnostics done on your neck ? Headaches often are caused by upper neck injuries. The injuries are subtle and may not show up on MRI's or CT Scans. The common symptom is a tenderness at the bony part behind the ears. This is significant of a spasming muscle due to trauma.

Some gentle traction with gentle manipulations may help. Icing can also help. It also requires serious discipline with neck and head posture, especially when sleeping or resting.

You might ask your doctor about a short term script of Soma (carisiprodol), a muscle relaxant or something similar to see if muscle spasms are part of your problem. Be sure to use good resting posture when taking a muscle relaxant. You don't want to make things worse.

Hope you can find a way to get some relief.

My best to you.
