Tortilla Soup - Gluten reaction?

This could have been a corn reaction but I didn't get the breathing issues (asthma-like, coughing, tight throat, difficulty breathing and especially the fingers cracking/swollen). I had symptoms that seem to be my gluten reaction including swollen belly (like I'm a couple months prego... see photo left) and itchy, white, pimple-like bumps (tiny) on my hand. The exact area was below my thumb knuckle and my wrist. The next morning my reaction was that I had to diarrhea - immediately when I woke up. This is very typical with my gluten reaction. I would be constipated and then all of a sudden have to go, and it is either messy or just smells terrible. Last night after eating I also felt like I had to poo - but never could - so I think that was the constipated time.

The tortilla soup was completely made from scratch (veggies) except for Rapunzel bouillon (vegan and safe), one can of Centos tomato paste (just tomatoes) and the most likely culprit: Tyson Chicken which is up to 15% broth. The ingredients did say "natural flavorings." One other item has been a little suspicious as well. I toasted some brown rice Food for Life tortillas but my sister says the company tests for corn and claims to be corn-free. Their xanthan gum is grown on corn syrup however.
