The left head, neck and tongue movement picture is still changing. In a strange way it almost feels like someone else is making the movements. I often play with it long enough that there is quite a bit of pain. I suffer from the illusion that if I keep playing with it long enough I will break through the restricted feeling but I don't know. It is feeling more and more like I have two separate movement images of the head and I was only aware of the right. I identified the movements through the right side image with the left neglected or never developed. I may or may not be correct in my thinking and I am very unsure if there is any benefit for me to continue to play with this. The pain would be a good indicator not to.
