A tendon of pain behind the left ear may be caused by acute mastoiditis, otitis major neuritis and postauricular lymphadenitis.
1. Acute mastoiditis: this disease is mostly secondary to acute suppurative otitis media, caused by the virulence of the germs, the patient’s physical weakness and poor drainage of the middle ear. Due to the accumulation of pus in the mastoid and middle ear cavity, it stimulates the distribution area of the trigeminal nerve, which produces dull pain or throbbing throbbing pain in the deep part of the ear canal, temporal part and the back of the ear.
2. Otitis major neuritis: Otitis major nerve can be divided into the anterior branch, the earlobe branch and the posterior branch, of which the posterior branch is distributed in the skin behind the auricle and the mastoid process, which can cause paroxysmal stabbing pain and throbbing pain in acute viral and bacterial infections.
3. Post-auricular lymphadenitis: this disease is often caused by various purulent inflammations in the head and neck, especially in the ear. When the lymph nodes behind the ear are involved, localized enlargement and fluctuating ear pain often occur.
When a tendon of pain behind the left ear occurs, it is necessary to actively seek medical treatment for systematic examination in order to clarify the diagnosis.
