Hey! I had almost the same thing happen to my little girl a few weeks back. I don't remember it feeling warm to the touch though but after fussing over it (we were supposed to get her pictures taken that weekend) we all ended up deciding it was a bite of some kind. I'm still a little miffed about it because even though it's gone, I can still see a tad bit of redness where it was- I don't think anyone else notices it but I do. I got told by family that if it was food allergies, it would have been more than just one mark though.
