What causes a cartilage clicking sound in the throat when swallowing saliva?

It is usually normal to hear a cartilage clicking sound in the throat when swallowing saliva.

The throat and neck consist of various cartilages, muscles, and fascia connected together, with each cartilage joined by joints. Swallowing involves coordinated movements of joints, the neck, larynx, and esophagus to transport food from the pharynx through the esophagus into the stomach. During this process, friction among cartilages, joints, muscles, and fascia inevitably produces sounds, which may travel via the Eustachian tube to the eardrum. Adjusting body posture or gently massaging the neck before swallowing saliva may help eliminate these sounds, which typically resolve on their own. However, bacterial infections causing inflammation of the throat cartilage can also result in such noises during swallowing, often accompanied by systemic symptoms like fever. If clicking sounds occur alongside other discomforts during swallowing, it's important to seek medical evaluation promptly to identify the underlying cause and receive appropriate treatment. If no other significant symptoms are present, neck massage may help relieve the condition.

In daily life, maintaining a positive mental state, drinking plenty of water, and avoiding excessively cold, spicy, or irritating foods are recommended. Regular physical exercise can also enhance immune function and help prevent illness.
