It is likely that you are experiencing a bit of eustachian tube dysfunction. The eustachian tubes are tiny tubes that run between the back of the throat and the middle ear (the part of the ear behind the ear drum). The function of the eustachian tubes is to drain fluid from the middle ear into the throat and also to equalize the pressure behind the ear drum.
Sometimes, the eustachian tubes become inflamed and do not function properly. The most common cause of eustachian tube dysfunction is a viral infection like the common cold. Other causes include throat infections, nasal allergies, and chronic sinus congestion. With eustachian tube dysfunction, fluid may collect in the middle ear because it cannot drain properly. Then, with a yawn or chewing motion, or other maneuver that opens the tube temporarily, the liquid and pressure may suddenly be relieved, leading to the popping sensation.
Generally speaking, eustachian tube dysfunction like this does not require any specific treatment, as it tends to get better as the congestion or cold symptoms resolve. However, it would be worthwhile seeing your primary care doctor
for a quick checkup to make sure there is not a more serious cause, such as an ear infection
, that does need treatment.
