After 28 years I found my trigger.
Grass pollen cross-reactivity triggers delayed my dyshidrotic eczema. My skin improved after eliminating certain foods, and the blisters returned completely
I've had dyshidrotic eczema for as long as I can remember. I had no idea what was causing it. I made many diets and tried really a lot. Last year was my worst year and I became my first panic attacks, because my skin was so bad. But in this year I realised that I have a pollen allergy. Sounds bad, but in my case it was good. Let me explain:
I only discovered last year, at the age of 27, that I have a grass pollen allergy. Before that, I had never noticed any typical allergy symptoms. Allergic symptoms can first develop later in life, even at 30, 50, or beyond, without realising that the person is the hole life allergic to it.
If someone is allergic to grass pollen, their immune system may recognize similar proteins in certain foods as allergens because they resemble proteins found in grass pollen. As a result, the immune system may react to the food (for example Oats) as well, even though the person is not actually being exposed to pollen. This is called pollen-food cross-reactivity. You will find in the internet many lists about pollen cross-reactivity.
After discovering my pollen allergy, I started looking more closely at pollen-food cross-reactivity and the foods I was eating. Interestingly, I realized that some foods associated with my cross-reactions might be affecting my skin, even though I rarely experienced the typical symptoms people associate with food allergies. The only exception I've clearly noticed is pepper in a big amount, which can sometimes cause slight swelling in my mouth. Otherwise, I generally don't get the typical oral itching or tingling associated with pollen-food syndrome. Because I wasn't experiencing obvious symptoms, avoiding these foods never seemed necessary to me.
Two months ago, I decided to completely avoid the foods I suspected were associated with my pollen cross-reactivities. Since then, my skin is the first time eczema free in my hole life. That's so crazy.
I took part in a food provocation test and reintroduced one of the suspected foods. The timing is what makes this particularly interesting to me. My skin doesn't necessarily react immediately after eating these foods. Instead, the eczema seems to flare up the following day.
I know that pollen-food syndrome is usually associated with immediate symptoms in the mouth, lips, or throat, whereas dyshidrotic eczema is a different condition. I'm not claiming that grass pollen cross-reactivity is definitely the cause of eczema in general. But there are some cases where people experienced the same as me. I hope you're doing well guys!
