That is where i get problems, right at the base of the skull, and under right shoulder blade, had this problem for years, and been going to chiro and osteopath when i get really bad with it. It has never solved the problem though just relieved it and loosened it up. I know what you mean about tension. It can also cause anxiety, well it does with me anyway. I've also been looking into acid ph balancing, because an over acidic body can cause muscle stiffness, and can pull you out of alignment. I bet parasites cause the body to be acidic!! I'm glad your problem is better. I mentioned in another post that my hips felt looser today when i went for a walk. Strange, but it was noticable. Until i found curezone i never contemplated that i could have parasites or worms. People really are in the dark about this problem. Thinking of writing an article to a health magazine hilighting the problem.
