Hi, Need to know more details about symptoms like duration, whether rashes are raised, whether you are on any medications or eaten any new food item. From whatever details you have provided there is a possibility of it being urticaria. You can consult online for treatment after a complete detailed history is obtained. If it is urticaria it shouldnt be ignored as angioedema can also happen which may be life threatening.
