Hi Manuela and welcome to the forum!
To answer your question, yes, yes, and yes on several of your symptoms and ailments.
Hopefully you've been through the worst of it now ... and you'll eventually feel much better on a gluten-free diet.
In the meantime, in case you aren't aware, it's important to continue your usual diet until the testing is complete.
Wishing you the very best!
Thank you very much. Unfortunately, I have been on a paleo diet since November, so I am not sure I will get a positive reading. I haven't eaten grains in any form since then. My doctor is aware of this, though. I am not sure how to get diagnosed on my current way of eating...
