The causes of otalgia are very complex, but in summary, there are mainly the following causes: First, otalgia may be induced by mental factors such as fire, mental anxiety, mental tension, etc. There are still some clinical cases. Second, there are inflammatory diseases around the ear such as otitis externa, otitis media, tympanitis, mumps, etc., so the local nerve of the ear is involved, resulting in pain in the nerve. Third, herpes zoster, a neuropathic pain that occurs when the herpes virus invades the nerves around the ear. The pain is actually very typical, and many patients still have pain after the herpes disappears. Fourth, inflammatory diseases of the throat such as tonsillitis, pharyngitis, etc., when swallowing, pain in the throat radiates through the nerve to the ear, which can lead to radiating pain around the ear, which is clinically very typical of pain. All in all, if you have neuralgia in the ear, you need to analyze it in detail with medical history and examination to see what is the cause of the pain.
