Hello. I don’t think the clicking sound is caused by a serious condition, it could just be the click sound produced when the Eustachian tube opens forcibly when you swallow saliva by force. It is a normal condition and you are probably highly aware of the sound, that’s all. You may perceive it on one or both sides, Nothing to worry about.
Next Steps
Can do steam inhalation two to three times a day, and the sprays used for allergic rhinitis help with Eustachian tube function as well.
Health Tips
If symptoms are too bothersome or new complaints develop, to consult ENT practitioner for endoscopy.
