Hi, in my experience the doctor is not always interested in figuring out what is causing your headache. He/she may just want to find what medication will treat it. Of course you want medication, but also what is causing the problem? Don't let them brush you off and not look into it further. Whether it is helping you figure out a migraine trigger or ordering follow up tests/scans, there is always something that can be done to try to find the cause(s). Hopefully and likely, your doctor will be proactive with this and will make this issue easier to handle. And as Nancy said, being prepared is very helpful.
