Yes, breathing it in seems to hurt me worse too! Ugh... its awful. Terrifying. I won't be somewhere with flour in the air. Period.
Good news is the thyroid thing DOES heal! I used to be so sick... literally shivering and unable to get warm at 70 degrees... I spent an entire winter sore all over my body from the constant shivering and having to soak in 2-3 hot baths throughout the day just to survive. No amount of blankets or sweaters helped... among other "broke down thyroid" symptoms like depression, exhaustion, etc.
I've healed a lot! I walked to the gym the other day in 50 degree weather in only a t shirt and light sweater! I can tolerate the cold so much more and my sleep, mood, and other things are much, much better now. I feel my thyroid works now. The longer you are away from gluten and other foods that bother you the more and more you heal, it just is a slow process.
So how long did it take for your thyroid to start functioning well enough for you to start functioning?? I am not functioning well at all right now and would soooo love to know that this was a temporary thing. Also as I said my Dr seems to be baffled about how to fix my thyroid if airborne gluten keeps impacting it so are you saying after a while your body stopped attacking it because of airborne gluten?? I am desperate for help right now but don't know who exactly can help me since my Dr seems shocked by my degree of sensitivity.
