Whether the congestion can heal on its own depends on the cause of the congestion. If the blockage is caused by cerumen (earwax), it can usually heal on its own. If it is caused by inflammation or a tumor, it usually does not heal on its own and requires treatment. If there is cerumen in the external ear canal, it will swell and block the ear canal due to water ingress, resulting in a stuffy feeling in the ear, which will heal itself after the cerumen is removed or the water is dried. If it is caused by a mass in the nasopharynx pressing on the eustachian tube, such as nasopharyngeal carcinoma, nasal polyps, adenoid hypertrophy, etc., it may also cause ear congestion, which also cannot be cured by itself and can only disappear through active treatment. If a patient experiences ear congestion, don’t worry too much. It is recommended to visit the ENT department of a hospital to find out the cause and cooperate with the doctor for targeted treatment.
