If you have several red dots on your ears, you should be aware of the following conditions: First, you should look for contusions on the auricle. If the auricular skin and cartilage are contused, there may be starry bleeding dots on the skin. Second, look for bites from insects. This is because insect bites, especially bites to the skin, such as those that occur when ants crawl onto the auricle, and lice, which used to appear frequently, crawl onto the auricle and cause damage to the skin. Third, also note that the appearance of red tops may be bleeding spots. The bleeding spot should be checked for routine blood tests to see the condition of white blood cells, platelets and other blood cells to see if there is a tendency to bleed and to rule out serious diseases.
