Hi Laura, I knew it was from you! I would let your allergist know about the cold hives and maybe get her tested for foods, if she hasn’t been already. I know they tested my daughter at about age 6, but only tested environmental things. Only after she developed chronic hives did they test for foods and we found out she’s highly allergic to shrimp, which she ate the day her hives started. Wish we’d known sooner! With the cold thing, your daughter may need to be on daily antihistamines like my daughter is. I don’t know anything about the EMLA cream, what’s in it?
