I had an Elisa blood test for 100 foods done. I’ve had dust and mold allergy for 35 years, but this flu like feeling I had was the first 3 weeks of this month. It made my symptoms much worse then they had to be. Instead of slightly dry eyes, the dust totally dried them out so I was blurry the entire day.
Going gluten free didn’t help, but it will once I heal enough since gluten intolerance destroys your defenses so food and airborne allergens become an issue.
