To read a whole series of posts dealing with scar tissue and petrified wood syndrome of the neck, just type in the Search box on the left hand side of the forum: "scar massage".
Be sure to put in the quotes. Hit Go and a screen will pop up with a whole series of threads on this.
For now, here is a direct link you can just click on that will take you to a post I wrote when my memory was much fresher back in May 2009 on your issue
