My baby is getting these rashes ( image attched) from last 2 weeks.. they come n go on their own.. sometimes they are large in number and sometimes few.. they most come on legs thighs hands and near the waist (where diaper belt is there) and 2-3 come on face also.. i have showed it to Dr. he said that it may be urticaria and they will go on their own! He hasn’t given any medicine.. kindly suggest when will it stop coming?
