Headaches affect many people around the globe. In recent times, Internet has helped many people know what they have, through online medic sources. What are the symptoms? So one goes ahead to see if their symptoms match the ones in the web page. Sometimes I really do not understand where they get the descriptions, e.g. “it is like a hammer inside my head” I know they said “it’s like” which implies it is something similar, but I don’t think it is near as bad as feeling a hammer inside the head. Back to the headaches, go and search the web and gaze through the descriptions of the symptoms, if you have felt nails in your eyes, flames inside your mouth or something similar around your head, it is probably not a headache, it is probably you doing something ridiculously insane. Just an idea.
