It is not possible to tell people about pain. I know many people with AS have been told it is in their head. So when Doctors can't find the problem it is your problem. You are responsible for your own health you can feel the pain. Lets face it even with a diagnosis "you have a progressive bone disease" it is hard to believe this is caused by what you eat. So it is our pain to treat and for me the only way i have been able to treat the pain is by diet and i am so pleased i found Prof Ebringer and this diet in time. George
