Her work specifically deals with the atlas and axis vertebrae, the area where the spine meets the brain. I had another appointment today and discussed this with her. She said that what she sees in all her patients with cluster headaches is a misalignment in this area 100% of the time. She said I am an average patient as far as my situation and that her success rate with patients finding relief is very high. I said 80% high and she said higher. She said not all patients with a misalignment will present with headaches, some may have vestibular problems, seizures, fibromyalgia, etc. just depends on what nerves and blood supply is being effected and how that is interpreted by the brain. She said most of her patients can recall a specific neck trauma in their past that may have caused a problem, car accident, fall. Some like myself cannot although I did play soccer thru college. I asked her why others refute that this technique works and she gave a multitude of reasons. The one I think is holistic practices are always at a disadvantage to prescription based treatments and also you may have to go to a few doctors before you find one that actually knows their stuff. Luckily I found one that does. Before my first appointment, I had to get very detailed xrays of my head and neck for her to review, then we went over my problem and she explained how she would correct it.
