Ear blockage caused by colds is mostly due to Eustachian tube blockage or secondary otitis media, which can be relieved by medication or physical therapy, but there is no quick solution. 1. Medication: A stuffy ear after a cold is most likely due to a blocked Eustachian tube and acute otitis media. It is usually recommended to choose medication under the guidance of a doctor, such as dexamethasone, ofloxacin, azithromycin; Vitamin C tablets, compound cold and flu; budesonide nasal spray, eucalyptus-pinocampus soft capsule and so on, in order to improve the symptoms and treat the disease. 2. Physical therapy: you can apply hot compresses to the nasal cavity, or do nasal laser, microwave therapy and positive and negative pressure therapy in the ear. In addition, yawning, chewing gum, swallowing and other actions can also promote the opening of the Eustachian tube and relieve ear stuffiness. Specific conditions and treatments after the onset should be evaluated and disposed of after examination by a specialist.
