It is normal to bleed when you have your ears pierced because the piercing will penetrate the local mucous membrane and cause the blood vessels to rupture. If the amount of bleeding is small, you can apply local pressure bandages and the bleeding will stop on its own after 5-10 minutes of compression in general. If you are still bleeding after 5-10 minutes or if the bleeding is heavy, you need to go to the hospital for a local checkup of the ear, as well as a blood count and coagulation mechanism to rule out any damage to large blood vessels or chronic bleeding due to abnormal platelets or coagulation mechanism. If blood is still leaking out 3-5 days after the ear piercing, consider whether there is a local infection, and go to the hospital to check the local condition for symptoms such as swelling, pain, pus and bleeding from the earlobe. If the above symptoms are found, the infection is considered to be present and symptomatic anti-inflammatory treatment should be given. At the same time, the earring studs should be removed and the infection should be controlled by repeatedly wiping them with alcohol or iodine volts to stop the bleeding on its own.
