My DD10 revealed yesterday that a few times in the last few weeks, when she has been eating, she has experienced chest discomfort (pain?) which has made her feel like she can't breathe quite as well and that in order to keep eating she needs to chew the rest of the meal until it's almost liquid! She says it has happened mainly when she has eaten strawberries or blackberries but she can't be sure it isn't other things too. Does anyone have any ideas at all what this might be?
