@pierwell I have not but I am thrilled they are tring to help you. I do know someone who suffers from Cluster Headacks and they are in the process at the moment. She has already had a treatment I think they are doing Botox? Is that what you will be given? I truely wish you the very best and hope this will be an answer or at lease relieve your suffering. I do feel for you, it is very difficult to live in a state of pain. So far My Nerve Block, Trigger injections, daily neck exercises, Clinical massage Therapy, using my Log Roll Pillow are my help. We will see never a day without some level of headacke. Keep us posted. Remembering you.
