Thanks batch I appreciate all the info will be reading through it as soon as I get home. My neuro ordered an MRI Monday when I saw him to rule other other causes and reviewed it with me today as well as doing the nerve block. I will admit I left with a few questions I wasn't sure how to ask him but he noticed an anomaly in my brain that my attacks occur on. He ordered a follow up MRI in 3 months to verify that it is stable and has not grown. He said that if stable it is most likely an anomaly in the venous structure of my brain which has been shown to have come correlation to CH. anyone with similar result ? Also he stated if the blocks do not work not to be discouraged because treatment has come a long way recently and there is more we can try. I just looked at the recommended doctors list he is unfortunately not on it but I will say from my experience with him so far I would definitely recommend him to others very understanding of the condition as well as seems to be very knowledgeable about CH treatment and research that is currently going on
