It is difficult to discuss Fibromyalgia Syndrome (FMS) without chronic pain entering the discussion. There are a lot of theories about what causes the pain and just as many theories that purport to offer a treatment to alleviate it.
Yale researchers believe that they may know what causes fibromyalgia patients to experience chronic pain. They base their theory that someone who physically exerts themselves describes their muscle pain the same way someone with fibromyalgia describes their pain. Advancing to the next logical step the researchers conclude that the pain felt by fibromyalgia patients is the result of vasomotor dysregulation and vasoconstriction in the muscles. Basically, it means that the muscles constrict, which in turn restricts the blood flow to muscles causing pain from the lack of nourishment to the muscle.
While some current preliminary data is consistent with the researcher’s hypothesis, they have been unable to locate any research material that would contradict their beliefs. Researchers feel that, with current technology, further testing is needed to confirm their suspicions.
