My daughter, 2 years old, had two episodes of facial swelling in two weeks period. Her face got swollen (and her hands and arms), but eyes, tougue and lips were ok. It didn't itch, it didn't cause her any breath problems and it was over in 20(!) minutes. Both episodes happenned in kindergarden, first outside, second indoors. They have no idea what might have caused it. No insect bites found on her. Doctor says it doesn't sound like allergy (because eyes and mouth stayed normal). Other than that she is perfectly healthy.
Do any of you have an idea what it is?
