A bleeding ear that goes left untreated, may lead to an infection in the ear that migrates to the bone behind the ear. Permanent hearing loss is also an effect, states Healthgrades. Life-threatening complications result in those who do not seek medical attention.
A bleeding ear can indicate a ruptured or perforated eardrum that can cause hearing loss, explains Healthgrades. A ruptured eardrum loses the natural barrier to the middle and inner ear, allowing for infection and potentially serious complications. If bleeding from the ear is the result of a blow to the head, this indicates a possibility of permanent brain damage. Bleeding from the ear can also be a sign of a more serious underlying condition. The bleeding can result from cancer; in this case, seek medical attention for evaluation regarding the cause.
Bleeding from the ear may sometimes appear to be a discharge of pus, wax, fluid and blood, notes Healthgrades. A ruptured eardrum, the most common cause of a bleeding ear, can heal on its own within a few weeks. Steps must be taken to avoid infection, because of the complications that can arise. It's recommended to contact a doctor upon any sign of a bleeding ear.
