My 18mth old daughter randomly broke out in hives.they start on hands, arms, face. has a cold/virus. dox said this is causing it. how? when to get 2nd

He's probably right: In kids this is usually a viral thing. If she started a new medication, like an antibiotic, it could be that. It's usually not considered a chronic problem until she's had it for 4 to 6 weeks. If it's bothering her try using Claritin (loratadine) first, then zyrtec liquid.

Viral urticaria: Most likely correct. May last days to several weeks. Treat with antihistamines and time.
