Hello, Flushing and blushing are common causes of red ears. They result in sudden reddening of the skin due to an increase in blood flow to the area such as in high BP. Typically, flushing occurs because of an intense emotional reaction, such as anger or embarrassment. You have just to keep your BP under control. If redness occurs when Bp is normal you can use something cold. If you can not control your anxiety or BP you should take an appointment with your Doctor. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Blerina Pasho, General & Family Physician
