Pain Modulation Syndrome Theory of Fibromyalgia
Fibromyalgia has been called a “pain modulation syndrome” because many patients feel great pain in response to seemingly trivial stimuli. Numerous studies have shown that it is not merely pain syndrome. There are, for example, important sleep aspects and many non-pain symptoms. It is therefore a mistake to characterize the overall syndrome as a pain modulation syndrome. The problem with this theory is that it over-elevates one important aspect of the fibromyalgia brain into the all-important cause.
