Hello. Posting here for hopefully more views.
I know no one can tell me the answer for my situation, I’m just looking for some personal experiences or insight.
Ultimately, I'm wondering if it is possible to experience immediate contact reactions to food only in the area it touches but have no problems eating it - and how likely this is to be the case.
My son gets a nettle like rash, white spots surrounded by red, when milk or eggs come into contact with his skin (peanut butter and hummus too). I have always assumed these were hives. They can look quite dramatic, but don’t seem to massively bother him and they usually disappear within an hour or so. He has eczema, which is moderately under control.
He also had tummy troubles from not long after birth and we were dairy and egg free breastfeeding. He has never really liked peanut butter and was sick once when eating hummus, though he had eaten it before.
Skin prick testing came up positive for milk, egg, sesame, peanut, and a couple of tree nuts. Apart from the tree nuts, this was not really a surprise based on the skin contact symptoms. He was prescribed epi-pens as a precaution.
I asked about food challenges but they said his numbers (wheal size I think) were too high at this point.
I’m new to this and it’s the constant wondering! We’ve not had any scary reactions since he has started eating solids and I’m not sure if it’s because we’ve just been really careful (we have but we still have these foods in the house) or it’s possible he wouldn’t have a reaction when eating these foods.
Do all people with immediate allergies get local hives after skin contact with the food they are allergic to?
Are people who get local hives on contact with food more likely to suffer a reaction on consumption or is this not an indicator?
Could it just be sensitive skin?
Does anyone get hives where a food has touched them but can eat the food with no problem?
Thank you if you got this far. Appreciate any and all experiences.
