Patient's question:
My baby is 5 years old; his ears occasionally turn red and feel hot, but not frequently. Previous treatment history and effectiveness: No treatment has been administered yet. What kind of assistance would you like: I would like to know; what causes the redness and heat; how it is triggered; and whether it can be harmful to his health.Doctor's answer:
Since the skin on the head, face, and ears is very thin and filled with rich blood vessels, when a large amount of blood flows through the ears, the vessels expand and become thicker, causing the ears to turn red. Because blood has a certain temperature, it will feel hot in the ears. Additionally, when the external temperature is low, the vessels contract in response to the cold, resulting in pale skin. At this point, if one steps out from a warmer indoor environment, the vessels suddenly expand due to the heat, and the ears will also feel hot and turn red.
