Intermittent throbbing pain behind the ear is considered to be related to otitis externa, ear boils, postauricular neuralgia and other diseases. 1. Otitis externa: During the onset of otitis externa, the stimulation of the skin and sensitive nerves around the outer ear by inflammation can trigger the clinical symptom of intermittent throbbing pain behind the ear. At the same time, there will be redness and swelling of the ear, increased secretion and other clinical manifestations, usually due to bacterial infection and other pathogens; 2. Ear boils: Various factors can lead to ear follicle blockage combined with bacterial and other pathogenic infections to trigger ear boils. When the pulsation of blood vessels in the ear stimulates the nerves around the boil, it can trigger the symptom of intermittent throbbing pain behind the ear; 3. Post-auricular neuralgia: Infection, temporomandibular arthritis and mental factors stimulate the nerve behind the ear, which can lead to increased sensitivity of the nerve and cause intermittent throbbing pain behind the ear as a clinical symptom. The pain may occur during mood swings and eating, and may be accompanied by skin flushing, excessive sweating, panic, headache and other clinical manifestations. There are many different types of diseases that can cause intermittent throbbing pain behind the ears, so it is advisable to go to a regular hospital for a clear diagnosis if necessary.
