Hashimotos – Eliminating Gluten

So for the last month I have tried eliminating Gluten to help some of my hypothyroid symptoms related to Hashimotos.

I still have found that after I eat I often get hives, anxiety, brain fog, etc. I know for the most part I am not consuming gluten, what else in my diet can cause these issues?
