Reintroducing foods

[crustymug]

So far with my reintroductions, they all passed the pulse test but:

Citrus – a teaspoon of an orange made my lips sting, and I refluxed it like the yellow stuff on an empty stomach in the gym (although I have reflux problems)
Legumes – Ears were burning but I may have just been in a hot room – P also expanded and became flakier but I had my first day in sun in a long time this day
White rice – my chest contracted after I ate it
Other fruits – no problem
Vodka– no problem

Is it normal for my body to act strange when I eat something I have not tried for over a month? Or should I take it as a sign to stop eating it?
I stopped eating citrus, legumes and rice all after less than one portion.
