All the #MCAS crew out there, you're going to love this gem 💎, from Sheffield NHS immunology department.
Apparently, when asked about my fatigue symptoms in relation to foods which have an onset of 2-24 hours, they replied to my doctor to say, allergy reactions are immediate, therefore delayed onset is not allergy. Therefore immunology doesn't want this patient and flipped me the bird.
Who would like to join me in presenting them with a list of delayed allergy reactions? I'll start with eczema. Not to mention those ones that go on for weeks after stopping the allergen - sorbitol for me at last record symptoms continued for 10 days after stopping the source food.
