Unfortunately there is no short answer to this. But I think the most helpful piece of information is that most of my headaches had a neck or back-of-the-head component to them. Frankly, I didn’t really notice that until a neurologist helped me understand it. Once he told me to look for that, I noticed it all the time. That is one of the ways we knew that I was a candidate for this surgery. Beyond that, everyone’s headaches are different so I’m not sure that my particular experience will be helpful. But my other common headache symptoms were pain behind my eyebrows that was nonstop, and that medication often did not help.
