@phoneboy Good job you got treatment. I have that sort of reaction to any form of aspirin - pretty much any salicylates. I made the mistake of spraying Ralgex on a bad back once - nearly killed myself!
Allergies seem to be through the roof lately (hmmm… 🤔).
You should find out what the cause is if you can, in case you need to carry an epipen. For me, antihistamines and my inhaler are must-carries nowadays. 🙄
