When I have prolonged exercise my face becomes red only on the left side while the right side is white and dry. My face will return to normal color after about an hour after exercise. I have no other symptoms that go along with this weird split face and this has been happening for years now.
I have had the exact same thing and this is the first time I've found anyone with it. There is a perfect line down the center of my face with one side pale white and the other deep red. It totally freaks people out when they see it. I find it particularly interesting that I have this and I am bipolar. The other thing that came to mind was the fact that long term alcohol abuse decreases the junction between the left and right brain. Although I don't really drink anymore I used to pour it on for years. Do you have any idea what this is since you posted this article?
