You are in Member Communities . Kathryn, I know the feeling of still being new to this. And trying to figure out triggers. I have had allergy testing, and I had zero allergies, but I have found somethings that seem to cause problems.
Cardboard is pretty dusty.
What about gloves. If you are worried about being able to grip the cardboard, try finding some rubbergrip gloves. They work great. Anyway, I would go get tested, it might be worth it for you. All rights reserved.
