Many chronic illnesses have deformities or other symptoms that are easily observed by others.
Other chronic illnesses have few, if any, outward signs. Three of those invisible illnesses are Meniere s Disease, Fibromyalgia and Chronic Fatigue Syndrome. These three separate and distinct diseases share many of the same symptoms. They are all often misdiagnosed and are little understood by those who are not personally affected. Their diagnosis is more a process of elimination rather than one or two definitive tests.
