Probably: The allergic reaction may be controlled by using a children's antihistamine such as Benadryl, dosed for his weight. Please consult with your pharmacist. The other possible causes include an infection of the skin. Please see your pediatrician or have a virtual consult with Healthtap. You may upload a photo during the consultation. Avoid dust, contact with animal dander and use a gentle soap.

Yes,could be allergy: Sounds like hives or other type of urticaria rash. Treatment is easy - give diphenhydramine until rash gone for 24 hours. Follow bos for dosing instructions. Finding out cause is not so easy....about 70% of time can't figure out what the culprit was. Keep track of what he's eating and doing prior to onset of rash if it recurs. It can be a food, but also can be things like being out in the cold!
