I'm thinking of maybe a type of glaze or something?
I'm normally on this board for my dd1 (anaphylactic to dairy/eggs), so I'm quite familiar with allergies. But this was me - had a bagel from a shop, immediate tingling in mouth and after a few minutes started to feel odd and hot. After 10/15 mins I was puce red from the neck up, my pulse was sky high (maybe 140?), head pounding and I felt shaky. Took a benadril and an ibuprofen, and after another 20 mins or so started to feel better.
I don't have any food allergies, apart from scallops, which are pretty easy to avoid. I get some oral reaction with apples and bananas, but that's it.
The bagel was poppy seed, with tuna mayo and salad - all stuff I eat all the time. Can't think of what on earth could have caused this? Maybe some chemical glaze on the bagel? Any ideas very welcome, as I still feel wacked and my heart kind of aches, v strange and slightly worrying!
