Bleeding from the ear can be considered as a symptom of trauma, otitis media, external ear canal tumor and other diseases, rather than a harbinger of any disease. 1. Trauma: Usually, when pulling out the ear, inattention damages the outer ear canal or eardrum, which can lead to bleeding from the ear. Or when suffering from violence or impact injuries, the skin of the external auditory canal or eardrum will be damaged, resulting in severe pain symptoms, leading to bleeding discharge from the ear canal. 2. Otitis media: When otitis media occurs, due to the stimulation of acute inflammation and infection, not only the symptoms of fever, but also pus and blood secretion from the ear, which will cause hearing loss and tinnitus symptoms. 3. Tumor of external auditory canal: when malignant tumor occurs in the external auditory canal, the fast-growing tumor has its nourishing blood vessels, and when the tumor ruptures, bleeding symptoms appear in the ear. Therefore, when the ear bleeds, it is recommended to go to the regular hospital in time to clarify the cause of bleeding and carry out targeted treatment.
