It might not be what's ailing you but your post rings a bell with me - Ask your doctor to check your bloods for anti-gliaden antibodies - the test for coeliac disease (celiac sprue or gluten intolerance).
I have both MS and Coeliac disease.
Hope you find out exactly what's wrong and feel better soon.
