Is fibromyalgia caused by a chronic viral infection, and if so, what percent of cases?

We would say, more than 90% of the time, fibromyalgia is a viral condition. As you know, that is a kind of catchall diagnosis for many kinds of focal pains in the body with no other likely diagnostic explanation, and there are other circumstances giving rise to such symptoms. It can be simply the reawakening of karmic trauma through body memories stored in cellular consciousness with no appreciation consciously of this predisposing factor. It can also be the result of some other kind of localized pathology by a variety of organisms including parasites that mimic what happens with a chronic viral infection, impinging on nerves and triggering pain, but fibromyalgia is a vastly misunderstood disorder in almost every case, with chronic viral infection being the causal factor most of the time.
