Antihistamines sounds like something to try. I do get hayfever, so it might be worth the effort.

It’s like a headache pressure without any headache pain, and it loads up all the way down my chest. It can be very crushing in tropical heat, and possibly include headache pain with alcohol consumption. The heaviest moment I’ve ever suffered was a bit of a knockout pressure. Like concussion.

I’m usually very apologetic about it because you’re having a huge reaction to something a proud restaurant prepared.

If I see heavily glazed bok choy I get worried.
