Hi Kathi, he did from C3 to C6, I think. He also did the direct ON block since the last MBB set it off so bad. I'm also still getting the throbbing which I first thought was just procedure induced but I think its part of the ON. I'm glad to hear that this isn't uncommon. Although I've seen him three times already, I'm still learning about all this. Thank you for responding. It helps to bounce these things off of someone who has been there, etc....ellena
