is skin sensitivity to a food indicative of an intolerance to that food?

[Tuesday's Child]

Possibly. DD1 used to get a rash on her hands and around her mouth when eating egg. We'd try her with small amounts of egg about once a month. At one point the rash spread down her neck and chest and her lips swelled a little. I left it for a few months after that but kept testing periodically. She's been fine with egg since she was about 2.

It could be a sign of an allergy/intolerance showing up. My DS used to get a red rash around his mouth when he ate sweet and sour sauce, he has an allergy to soy. He would also get eczema which stopped once we eliminated wheat from his diet however would flair up on his neck after washing his hair - his shampoo contained wheat.

Could be indicative but not conclusive. I'm allergic to fish and get a rash/redness when I touch it.
