Hi Launa,

I'm Joy, the manager of the site.

First things, first, when you're dealing with a child who has a fever, you should probably head to your doctor right away or at least call the doctor's office. If you're really concerned, or if your daughter gets worse, you might want to go to the emergency room.

Hives are usually an allergic reaction to food or medicine. Do you know what your daughter was eating or doing right before she got hives? That would be important information for the doctor to know. If you know what it was, don't let her eat any more of that food (or touch, play with or sit on anything she may have been in contact with when she developed hives).

Swollen lips can also be an allergy symptom, possibly caused by whatever caused the hives.

Fever is not generally an allergy symptom, but that's all the more reason to see a doctor right away.
