Hi duck
I have had a similar experience to you, in that I have a mild to moderate constant daily headache that appears to move around in my head. The main difference seems to be that mine don't go away. My diagnosis was New Daily Persistent Headache, but I don't entirely fit that description either.
I take it from your comment that your headaches are relatively mild? How long have they been going on for (not this episode, but overall)? Have you seen a doctor about them? When the doctors thought that I had tension headaches, they suggested I have wine, cheese and chocolate - these should improve tension headaches, and make other types of headaches worse. It may also be worth getting a CT scan of your sinuses to see if there's any problems there.
I have found that the biggest things to help me are:
- a grain free diet (there is an article available on the internet called 'General reading for people with immunocereal diseases' which explains the science behind why this helps people with chronic illnesses)
- a herbal tonic from my naturopath
- being distracted by something I'm interested in.
I haven't found any drugs have helped me for an extended period of time without significant side effects.
Hope some of these ideas can help you too.
