I'm new on this site. It is very difficult trying to follow directions on how to use this site, so I'm hoping this is working? I don't understand how a worker's comp doctor can, for 18 months insist that there is nothing wrong with me?? I have not been symptom free for 18 months, not for one day. I have begged her to help me and she continues to tell me there is nothing wrong with me except that I need exercise and more vitamin D. I am an athlete suffering from a closed head injury. How do I get help?
