Allergy?

I gave my daughter scrambled eggs today (like I have many times in the past) and she has a skin reaction almost immediately. She eats eggs almost daily, whether scrambled or baked into something such as baby French toast or pancakes with no issues.

The redness started immediately while eating then went away within 10 minutes after cleaning her up. It was only located on her chin, and she ate with her fingers and hands. Has this happened to anyone before? Could it be the oil I cooked them in, maybe a bit too oily? Or maybe there was a tiny bit of the eggs that weren’t fully cooked all the way and she has a skin sensitivity to raw egg?

I contacted ped just wanted other moms opinions.
