Thanks Mark. I try searching for "cervicogenic headaches" and check out the related therapies.

For some reason a search for "cervicogenic physical therapy" yielded very few results. I guess I was looking for an explanation of what the PT does and how the therapy works.

I'll do a little more research.

Btw, I'd love to hear about people's experience with the type of PT. I'm not sure what to expect but I imagine the PT will be doing most of the "work".
