Hi Adalaide! Sorry you are experiencing this on top of your CRPS. Hope you are feeling better now.
My allergies are way worse now than before...I am super sensitive, but have not had quite the reaction you did. I do also get migraines and scents can be a huge trigger for me. I understand what you are saying about sharing the kitchen with wheat eaters. Fortunately it is just me and my husband, he is the wheat eater and I cannot have gluten (among many other things). It is a struggle, but I have good control in my kitchen. Glad you will have your own kitchen that you can control.
Take care,
Nanc
