Hello Alan31, I see that you posted this question last May and I hope by now you have found the correct treatment but if not I strongly urge you to consider osteopathic manipulative treatments, or OMT. I have cervicogenic dizziness. It took three years and a good physical therapist to be correctly diagnosed. The only thing that works for me is OMT. I have to go every three weeks but it worth it. I saw that you have seen an osteopath but you need one that will spend 45 minutes at each visit treating your whole body for this. Try reseaching the Osteopathic Association in your area to find someone who does this. Treatments can change the way you live your life and provide you with a great deal of understanding about it. Hope this helps!
