Ear pain needs to be alert to diseases such as inflammation of the external ear canal, otitis media, ear canal injury, and inner ear tumors. 1. Inflammation of the external auditory canal: boils on the auricle and external auditory canal, otitis externa, swelling of the external auditory canal and other causes can cause ear pain and discomfort. 2. Otitis media: Pathogenic bacteria enter the middle ear through the Eustachian tube causing ear pain, accompanied by sore throat, cough and other symptoms. Especially before the tympanic membrane perforation, ear pain is more intense, after the perforation of pus, ear pain will have a certain degree of relief. 3. Ear canal damage: for example, pulling out the ear, hard otolith and other reasons may damage the ear canal, causing ear pain. 4. Inner ear tumor: advanced middle ear cancer may cause ear pain. When ear pain occurs, you need to go to the hospital for examination and treatment in time to avoid delaying your condition.
