[|Human|] My three year old son has been fighting a cold for 2 days .... Tonight at bath time I noticed a rash on his back not raised and not itchy, about 2 inches in diameter.  After the bath the rash looked better.  An hour after falling asleep he woke up and vomited.  Now he has nearly a dozen of the rashes on his back, shoulders and face.  Wondering if this is cause for an emergency room visit?
[|AI|]  Hi... by what you quote I feel that this could be urticaria or a skin allergy of some sort. I suggest you take him to the emergency room. But meanwhile, you can use HY Chat Doctor.  Most important thing to be remembered is that it has a propensity to recur (called as second crop) within 10-14 days. If this happens, you can start using the same medicine, but I suggest you get the kid evaluated with your pediatrician. Regards -
