Hi Mary,
I was diagnosed with MS in 1998. A gluten free diet has helped in that my neurological symptoms have not gotten worse. However, I have had tingling and numbness in my feet and legs for many years. There really never seemed to be a reason. This summer I had delayed food allergy testing run by York labs
http://www.optimumhealthresource.com/ because my son had been found to have a lot of food allergies. I learned I had high reactions to dairy, eggs, soy, legumes, citrus and a few other foods in addition to gluten. Since I have removed these addtional allergens from my diet I have had a substantial decrease in the neurological symptoms in my legs.
Cara included this in her comprehensive response but I just wanted to let you know what has helped me personally.
