Cortical plasticity in episodic and chronic cluste in Research & Scientific News Posted December 14, 2014 DM- cool stuff. I can't even start to figure it out, some of my dreams the TRUTH is just so clear and it kills me that I get this kind of "this is disturbing" feeling, yet feel very comforted in "knowing", what I cannot remember as soon as I wake. This has nothing to do with medication for our condition, it is entirely outside of that (e.g. I am not tripping I had an interesting experience with the last maintenance therapy where I started behaving like I was having a cluster and just felt like pushing on my skull and crunching the top of my head and I started to freak and then I was like, "there is no pain at all, why am I doing this?" No idea. It's like I was having a cluster and I was reacting to it, but I could not feel the pain, so I was dumbfounded to sit there rubbing my head for no reason. Hmmm. Very interesting thread, thanks again.
