Well, the company president called me and assured me that they make potato chips only, and they make two flavors only. None of DS's allergens are used at all. And they do random testing for gluten, peanuts, and tree nuts and always come up negative.
So. It seems to eliminate the chips. I have no idea what caused the reaction. They served a bunch of cheesy things in the cafeteria that day, and I wonder if he somehow got into some cheese on the table or on a doorknob or something, but he scoffs when I suggest it. I dunno. We're just not gonna know, I think.
He and I were both exhausted yesterday; DS stayed home and slept until 2:30. The allergic reaction and esp the epinephrine seemed to really take it out of him. It took over an hour for him to stop feeling (visibly) jittery. I told him it must be like running a marathon, the way the epinephrine can affect the heart etc.
Me, I think the fear took it out of me. I had the phone call in which they told me he'd had a reaction and they used the epi and the ambulance was on the way -- no other info; I heard the sirens as I jumped in the van to race to the school, and had no idea what I'd find when I got there. Then I had to follow the ambulance, although by then I'd seen him and knew the epi had done its job and he was doing better.
Auvi Q is not covered by our insurance, and at $300 each --- umm, not gonna happen anytime soon. The school is used to epipens --- the other allergic kids also have epis, so it doesn't seem wise to change it up. But for him to carry for his own use, yeah, it would be better. Thankfully he did shove BOTH epis into his jeans pocket today instead of just one.
