There are many factors involved in this chronic illness. There are common symptoms, but the source of a symptom may not be of the same origin. While you may generally have ME/CFS, you may have manifested a co-morbidity, such as cholecystitis. Also, each sufferer has a unique genome that dictates co-morbidities, as well as, necessary dietary intervention. Have you had genetic testing and/or identified past/present infections?
