I have just read a wonderful book, provided to me by one of my patients. It details many causes of dysautonomia. It has a patient side and a physician side which discusses the topics of each chapter in clear language from both a lay perspective and professional perspective. Wonderful resrouce to anyone who is struggling with chornic pain, "wonky" symptoms (my word...;) ) or anything that just seems to confound many practioners. Almost eveyr person who has had some type of chronic pain has some form of sensitization. I have experienced this myself with abdominal pain. There is hope though and we can begin to reverse aspects of this disorder. 

Take a look at the link below for more info. Of course we at Bluegrass Doctors of PT will always be resources to our patients on this topic.
