I just noticed that my 6 years old son has a lot of blueish red flat small spots on his chin and juste below it.  It almost looks like he hate blueberries or raspberries.  He was not feeling well today, he had a sore tummy so I kept him home.  Could it be a child illness or just a contact allergy?
Hi, Welcome to Chat Doctor, In dermatology, skin conditions are difficult to evaluate without actual examination. As per your description, it could be acne or some allergic bumps which needs to get examined. Also, provide more information regarding these spots, Whether they are painful or spreading? Is there any fever? However, you can give antihistamines syrup (cetirizine) to your child twice daily. If this red spots remain persistent then you need to see some local doctor or allergic specialist for complete evaluation.
