Do you need to go to the ER for a small alergic reaction even if you take benadryl?

depends. what kind of reaction are you having

I would go especially because you gotta make sure your baby is OK.

I mean, I know allergic, but it happens at so many different levels and "symptoms"

@emily18234, my chicken was cooked in the same fryer as fish. my checks are swollen and my throat alittle but it's been like 2 hrs since I ate and my breathing is fine.

then absolutely.
