External ear canal pain

Introduction: External ear canal pain is a type of ear pain. Ear pain is a common symptom, which can be divided into three types: otogenic ear pain, reflex ear pain, and neurological ear pain. Otogenic ear pain is also called primary ear pain, which refers to ear pain caused by ear lesions. Reflex ear pain, also known as secondary ear pain, is because the nerves that govern the ears also control the sensations in other parts, so pain caused by lesions in other parts can be reflected to the ears through the nerve to cause ear pain. Neuropathic ear pain is pain caused by lesions in the ear's sensory nerves.
