#asktheexperts ...my baby has rashes in his upper arm for 3 days, there is no other symptoms. what may be the cause? should I consult with a pediatrician or a dermatologist?

A. As of now if you want you can use calamine lotion but this is not a rash this is some kind of an allergy that is developing on the skin so you better be sure about it after getting it checked with your doctor the doctor will be able to diagnose the issue and kind of an allergy test and accordingly right treatment can be suggested
