Hey Emma- first off, I am so sorry you are going through this as I know this pain. I didn’t have eczema but would get a hiv-y like rash all over my skin, especially my face and legs which was not only uncomfortable but you feel hideous. I tried all the things, switching to even less scented/chemical products, supplements, alergy tests and I was already pretty clean food/product focused.
My boyfriend suggested that we start doing fresh celery juice which helped somewhat but led me to doing the whole30. Doing this totally cured his eczema and cleared up my face and all rashes/outbreaks in 15-20 days. The correlation I found to food doesn’t make sense with any allergies and more has to do with inflammatories and foods that grow mold (like some nuts and not others.) All that to say I highly recommend that you try some sort of a reduction diet so you can figure out what is going on. The fresh celery juice first thing in the morning – 30 mins prior to coffee or any food, really helped to expedite the process. I can now have those foods in moderate quantities so I feel like it helped me to re-baseline and now I can live with everything in moderation. If you have any questions feel free to reach out!
