Suzanne Romey just posted a summary of a possible connection between
fibromyalgia and celiac disease. Here is a paragraph that Ron Hoggan wrote
some time back:

The anti-endomysium antibody test has been shown to be a very reliable
indicator of the presence of celiac disease in those who are not IgA
deficient. Since endomysium tissues penetrate into the interior of each
fascicle, covering and separating each muscle fibre, an autoimmune attack
on endomysium tissues should result in the symptoms we call fibromyalgia.
Ergo: celiac disease should usually be accompanied by fibromyalgia, and
fibromyalgia should usually herald the presence of antibodies which are
diagnostic for celiac disease.
