Pain near the ear when chewing may be related to TMJ disorder, otitis externa, oral diseases and other causes. Patients should treat the symptoms. 1. Temporomandibular joint disorder: If the patient has recently received stomatological treatment, which has caused changes in the occlusal relationship, or sudden changes in chewing habits, it may cause lesions in the temporomandibular joints, which will cause pain near the ear when chewing. Patients can use ibuprofen, sertraline, dexamethasone and other medications under the guidance of a doctor to relieve symptoms. 2. Otitis externa:If the patient has inflammation of the external auditory canal, it will also affect the temporomandibular joint, so when the patient chews something, there will be pain around the ear. Patients can follow the doctor’s instructions to use topical drugs, such as amoxicillin, levofloxacin capsules, roxithromycin tablets and so on to relieve symptoms. Drugs need to be used under the guidance of a doctor. 3.
