I've just taken a mouth reaction allergy to the ready meal macaroni cheese I've just eaten. it was an 'improved recipe' but I used to be fine with it. Looking at the ingredients, the three possibilities are: nutmeg, pimento, mustard flour. I'm sure I've eaten all of these before.
I'm allergic to many nuts (worst with peanuts) but haven't had a reaction in a while. I did react to a few different curries that I was previously OK with when pg. Can you develop new allergies in pregnancy? Are any of these spices in curries?
