In patients with auricular pain, the first thing to ask is the nature of the ear pain, such as throbbing pain, pressure swelling, pinprick-like pain, knife-like pain, tearing pain, and pulling pain. The pain can be mild or severe, and the duration can be long or short. There is spontaneous pain, but also pain when chewing and swallowing; there is deep pain in the ear, but also radiation to the ipsilateral head and neck, etc. It is important to pay full attention to the various features of its accompanying symptoms so that appropriate tests can be performed and the diagnosis can be confirmed early. Auricular pain needs to be differentiated from the following symptoms: 1. Pain in the root of the ear: It can be seen in otitis media, and oral tumors can also cause pain in the mouth and the root of the ear. The most common symptoms are stuffy or blocked feeling in the ear, hearing loss and tinnitus. It often occurs after a cold, or unconsciously. Sometimes the hearing can be improved by changing the head position. There is self-hearing enhancement. Some patients have mild ear pain. Children often show dullness in hearing or inattention. 2. Pain behind the ear: The mastoid behind the ear is a part where the facial nerve travels, and the facial nerve travels inside a very narrow facial nerve foramen, so when the facial nerve is attacked by a virus and becomes edematous, pain will occur when it is compressed. Therefore, pain behind the ear after a cold may be a precursor of facial palsy.
