Sometimes there is so much chatter and clutter on the Internet it is hard to know what is the best information about headache disorders. Patients often bring me articles that they have copied from blogs and discussion groups. I would say that half are good and half are very dishonest, trying to push some worthless treatment for headaches on vulnerable sufferers.
One of the best places to get reliable information is from the American Council for Headache Education. It is a patient information arm of the American Headache Society. They have no hidden agenda except to find honest information for the headache sufferer.
