When the eardrum is accidentally punctured and bleeding, the first thing to do is to go to the otolaryngology department of a regular hospital and perform an otoscopy to determine if the eardrum has been punctured. In the case of bleeding ears, it is not necessarily a punctured eardrum, but a punctured outer ear canal. A punctured eardrum will not only bleed, but will also cause a loud booming sound, tinnitus, hearing loss, and ear pain. The external ear canal is 2.5-3.5cm long and S-shaped with two narrowings, both of which are designed to prevent direct external damage to the eardrum, and in most cases the bleeding is caused by poking the skin of the external ear canal. If the eardrum is really punctured, there is no need to worry too much. If the eardrum is not infected, it can heal naturally in about two months, except for particularly large perforations that require surgical repair treatment.
