My wife suffered the same. She consulted a nutritionist who after hearing her symptoms suggested, with much suspicion from me, that she try the elimination diet from the Royal Prince Alfred Hospital’s allergy unit: https://www.slhd.nsw.gov.au/rpa/allergy/resources/foodintol/ffintro.html https://www.slhd.nsw.gov.au/rpa/allergy/resources/foodintol/... And now we know that she can’t ingest a high level of saicilates without complications. I still struggle to reason about what foods prepared in what ways meet the criteria (the book at the URL above maps it all out, I’ve just been unable to build a mental model/pattern match in the same way I can on carbs vs proteins) but I no longer have any doubt that these are the triggers. Hopefully the same process helps you out too.
