No one knows for sure what causes fibromyalgia, but physicians and other experts have many fascinating theories to explain what may induce the onset of Fibromyalgia Syndrome (FMS). The cause could be hormones or an autoimmune problem or biochemicals gone awry, chronic stress, or it may be related to a previous trauma, such as an injury that you incurred in a car crash or in another serious accident. Individuals who have been abused as children or adults are more likely to develop fibromyalgia than others.
The cause could also be a combination of different factors coming together at just the right time (or the wrong time when you think about it) for you to develop FMS. For example, maybe you got the flu, and then were involved in a serious accident. Or some other awful combination may have occurred.
As researchers (like me) continue to study this medical problem, they move closer to the truth. Speculating about causes can be fascinating, and some common theories for what causes fibromyalgia are continuously being formed.
