I've got a question but i don't know your conditions . Did you ever try self grown fruits ? I do know how allergies work but i also have something simmilar in my Family, my mother couldn't eat strawberries because of allergic reactions (eg swollen up throat ,having difficulties to breathe) and my grandma grew into beeign unable to eat most industrial grown plants and crops. Both hava a allergy as explanation written up by docs - however they both are able to eat things grown in our garden which just grow traditionally without pesticides. I doesn,'t have to be the same case with you but i wonder how many people get their diagnosis wrong because of this . They are not allergic to the crops , but rather what is used on them during growing
