Many people wonder exactly what causes Fibromyalgia, since there was never a definite answer, some question if the disease is even real despite the pain being there. One thing to note is that Fibromyalgia is not a delusion even though many psychologists have had difficulties diagnosing and classifying the disease.
Fibromylagia might be a body-wide symptom disorder as a result of many contributing factors. Some research studies suggest a relationship to the developmental and dysfunctional genes controlling the levels of certain neurotransmitters. Additionally, some scientists believe that since fibromyalgia is linked to psychological factors then it should be categorized as a somatic symptom disorder.
