I know i'm a bit sensitive to kiwi (tingly itchy mouth) but appear to have had the same thing only worse after pineapple.
Ate it yesterday evening and had itchy face and mouth all evening and didn't twig.
Just looked in a mirror for the first time today and noticed it's all little scratches all round my mouth and chin (thought it was a bit sore but haven't got round to looking)so maybe i was scratching in my sleep or something (although i have no nails to scratch with).
Anyway - the rest of the pineapple is sitting looking tasty and delicious in the fridge.
Should I test my theory or not?
