Bleeding due to ear-digging is usually caused by injury to the external ear canal or perforation of the eardrum. The external ear canal is relatively deep and narrow, so if the ear-digging is done carelessly, it can cause damage to the walls of the external ear canal, and because the nerves in the external ear canal are sensitive, the pain is severe after the injury occurs. Patients need to go to the hospital to examine the external ear canal to get a clear diagnosis. If an injury is found, it is usually necessary to take oral anti-inflammatory drugs to avoid local infection and to avoid water in the external ear canal, which can be cured in about a week. In contrast, tympanic membrane perforation is usually a small circular perforation with fresh blood attached visible in the tense part of the eardrum. The patient will experience ear pain, hearing loss, tinnitus and other related symptoms. This tympanic membrane perforation also requires oral anti-inflammatory medication to avoid local infection, as well as avoiding colds and not blowing the nose hard, and it will heal itself in about a month. If it does not heal on its own after one month, then tympanic membrane repair can be performed.
