As you mentioned, there are indications of a hypothyroid condition even though she was tested and it came back normal. In an interview with Dr. David Derry http://www.thyroid-info.com/articles/david-derry.htm He states that based on his experience, he feels that Chronic Fatigue and Fibromyalgia are caused by low thyroid. He went on to write a book on breast cancer and Iodine: https://www.amazon.com/Breast-Cancer-Iodine-Prevent-Paperback/dp/B00QD9FDFY and this book actually touches quite a bit on Fibromyalgia symptoms.
