I am not sure about the brace. I would ask if you have rsd in the neck for ex if it should be in something like that. I know and this is different but I wore an airboot that made things worse because I actually needed more movement rather then less. Now yours may be totally different but a thought that came to my mind. Have you tried topomax? I know some of the peole in the pain clinic who had severe head aches were on it. I am assuming with scs you can't have an mri but I was wondering before if you ever had one of your brain? I hope you feel better
