Gluten very definitely can cause neuropathy, that's how I got my sensory neuropathy. Has anyone checked your B12 level? Gluten intolerance causes you to malabsorb your vitamins and minerals, which in turn will cause nerve damage. B12 very often is a hugh issue, as can be Vit D.
Do you feel better gluten free? I have been gluten free for 10 yrs, after about 4 yrs, I also had to be corn and soy free, then the nightshades went, followed by cruciferous veggies, and now, I eat no grains, no dairy...BUT, am doing much better.
Don't give up. Getting the gluten out of our systems is a slow job, and you must be sure that ALL gluten is gone. Read the labels on everything you put in your mouth, the processed foods are the worst. The fewer the ingredients, the better. I eat nothing processed anymore.
