Neuralgia above the left ear clinically has the following possibilities: First, some patients have auricular herpes zoster and the herpes virus invades the trigeminal nerve causing a painful sensation in the branches of the trigeminal nerve above the ear. This pain can occur in the pre-herpes onset and in some patients for some time after the herpes disappears. Second, the inflammatory stimulation of the ear itself leads to pain. Some patients, such as those with acute otitis externa, herpetic tympanitis, acute purulent otitis media, and the unperforated period of the tympanic membrane, can experience significant pain in the ear, and this pain stimulates the nerves around the ear and causes pain. Thirdly, some patients have no obvious inflammation in their ears or ear canals on examination, but the patient will have pain. This may be related to the nerve pain induced by the patient staying up late, eating spicy and stimulating food on fire, working anxiety and tension. Generally this condition can be treated with symptomatic treatment with drugs such as carbamazepine, but the effect may not be good in some patients after a period of time.
