To the original poster it sounds an aweful lot like ascaris. Ascaris can do that. It's heartbreaking to have a parasite travel around your skull, well everywhere in your body, let's just put it that way. I got to a point where if they were in my chest or arm I would simply crush them. One natural thing that has always helped me has been eating a coconut everyday. I am going to try putting different oils on them. With levamisole I got rid of so much stuff. When I routinely take it I don't get too much out. When I eat coconuts regularly I constantly eliminate the same things. It's just what happens. It may not get rid of them completely but it keeps them at bay.
