YES! this is what I experienced for the most part before I was diagnosed last week. I didn't have the typical stomach issues I had fatigue, brain fog, bone/joint pain that radiated my whole left arm, neuropathy, insomnia. My Doctor ran test for everything under the sun and Celiac's is what came back positive. So I feel your pain literally. I have been gluten-free for 6 days and have noticed a small improvement but still have a long way to go.
