Yawning is a normal physiological reaction that everyone will have, but some yawns will hurt in their ears. What's going on? There may be the following reasons for your reference:
The ear and nasal cavity have interconnected pipes in the throat area - the eustachian tube. Its lumen is very small. When the throat is inflamed, it will locally swell, resulting in the blockage of the lower part of the eustachian tube, resulting in different pressures on both sides of the eardrum. When yawning, a large amount of air is taken into the lungs, and the facial muscle activity increases, which will increase this pressure difference and cause ear pain.
Ear canal inflammation can also cause blockage of the eustachian tube, but there are two situations: one is local swelling of ear canal inflammation, resulting in blockage; the other is pus in ear canal inflammation, flowing into the eustachian tube, resulting in blockage. There will also be pressure differences on both sides of the eardrum. Yawning will increase this phenomenon and cause ear pain.
Temporomandibular joint disorder syndrome
Temporomandibular joint disorder syndrome is the most common disease in oral and maxillofacial region, and its pathogenesis is not fully understood. The main clinical manifestations of this disease are joint pain, joint bounce during exercise, jaw movement disorder, etc. this pain symptom will increase significantly when yawning, and will also extend the symptoms of ear pain.
The parotid gland is close to the ear. Some patients have parotid infection. The parotid gland is seriously swollen, and some even swell behind the ear. There are also different degrees of swelling inside the ear. It is easy to involve the swelling when yawning, causing pain.
Ear pain is also a symptom of getting angry. In traditional Chinese medicine, there will be tolerable ear pain due to kidney meridian deficiency and inflammation, and some are accompanied by dizziness and oxidation, which requires patients to nourish yin and reduce fire.
