I have severe eczema on face, neck, and shoulders. What should I do to manage it?

Hello doctor,

I have some questions regarding allergies.

When I was a kid, I had eczema on my mid-arms. Then it went away. Some years ago, when I was around 22, it came back aggressively on my face, neck, and shoulders. Then I was referred to blood food allergy tests (IgE). A lot of allergens were detected (wheat, melons, peach, cucumber, potato, parsley, carrot, etc). I did avoid those foods.

After seven years, I wanted to test it again, and unfortunately, the test showed the same results, more allergies (coconut, plum, chestnut, and buckwheat - things I eat regularly). I also did the FABER test and had a lot of red lines. The doctor told me that none of those tests are 100 % sure and I should test all foods. But I am very afraid of the anaphylaxis reaction.

I am now afraid to eat coconut, chestnut, etc., which I did regularly eat before not to have a severe reaction (not had one earlier though). I wanted to ask if the most severe reaction can develop with any food. Even for meals that I do regularly eat and have no problems with. Please help me.
