A small amount of blood will definitely flow from an ear piercing, but since the ear is not supplied with large blood vessels like other organs, the bleeding can usually be stopped by applying local pressure and bandaging. Also, there are different areas of the ear piercing that bleed differently. If the ear piercing is done in the earlobe area, the relative blood flow is poor and there are no large and thick blood vessels, mainly peripheral blood vessels supply, so the bleeding is not very large and may not bleed, generally by applying pressure bandages can be done without other treatment. If the ear piercing is done in the cartilage part of the ear, relatively speaking, the amount of bleeding may be more, because there is no major blood vessel supply in the ear, so in general, the amount of bleeding will not be very big, unless the ear piercing happens to be done in the area where the blood vessel travels. However, ear piercing is after all an invasive operation and there is a possibility of infection and infection. Generally speaking, we should observe the local blood flow and whether there is redness, swelling, heat, pain and other symptoms on the ear piercing area after the operation, and choose the right area for the operation to ensure that everything is safe.
