I have had a sudden onset of what my neuro thinks is SFN. Done tons of testing and my blood test shows might have Celiac Disease. I'm waiting for referral to have a biopsy of instestines to confirm the Celiac. My Dr. says I might have SFN due to the Celiac. Has anyone here had this and if so, will it get better if I do a Gluten Free Diet? I'm so desperate for relief!

BTW: B12 test was 580, but B1 is only 9.
