Not all patients diagnosed as having fibromyalgia have all of the well-established symptoms and objective findings of the syndrome.
Most patients have only a few.
However, from a scientific standpoint, the preferable explanation of the cause of fibromyalgia is the one that best accounts for all we know about fibromyalgia. Logical analyses of the available scientific evidence show that only one factor can cause all of the symptoms and objective findings of fibromyalgia. That factor is too little thyroid hormone regulation of cell function. Conventional doctors and fibromyalgia researchers have failed to scrutinize the available scientific evidence in the proper logical manner. As a result, they are unaware of the conclusions that the evidence overwhelmingly compels us to reach.
