--has suggested a celiac/gluten sensitivity possibility yet?

At the very least they should do blood titers for anti-gliadin IgA and IgG, anti-transglutaminase IgA, and total IgA (this last test, if it show overall low levels of IgA, may indicate skewing of the other test results).

You really should visit the Gluten section of Neurotalk (especially The Gluten File):

And have you been thoroughly investigated for autoimmune disorders (lupus, Crohn's)?
