The pain in the eye of the ear may be caused by infection of the external ear canal, otitis media, cerumen blockage and other reasons. 1. External ear canal infection. Due to otitis media, drug allergies, bad ear-digging habits, etc., the external ear canal is infected, resulting in burning and itching sensation in the ear, accompanied by small blisters and rashes in the ear, which causes earache. 2. Otitis media. Due to viral infection and other factors, otitis media is induced, which leads to hearing loss, earache, ear pus, and in severe cases, tympanic membrane perforation. 3. Cerumen blockage: Cerumen blockage is caused by excessive cerumen clumping, which results in hearing loss, ear canal swelling, earache and other symptoms. It is usually cured by removing the cerumen. After the onset of the disease, we should actively seek medical treatment, and standardize the diagnosis and treatment.
