Hi @emalloy, so far a definitive solution to clicking or popping hasn’t been discovered. However, most have discovered that the issue doesn’t point to a serious underlying medical condition.

I’m glad your doctor is investigating further and referring you to an ENT specialist. I know this can be scary and one tends to leap to the worse case scenario. But I wouldn’t leap to cancer. More analysis and investigation is necessary.

Is this a new issue for you since the recent cold you had in your family? What causes you to have the urge to swallow? Do you find that the urge diminishes when you’re concentrating on something that require focused attention or you’re distracted by doing something you enjoy?
