The most common cause of congestion in the ear is mechanical blockage of the eustachian tube, which causes abnormal function of the eustachian tube and leads to internal trapping of the eardrum. First, to improve the mechanical blockage of the eustachian tube, such as adenoid hypertrophy, rhinitis, sinusitis, etc., you can spray nasal medications such as auxiliary Schlamydia or Neshuo, together with rhinitis medications such as Cangerzi Rhinitis Drops or Nasal Yuan Shu Oral Liquid. Secondly, if the stuffy feeling in the ears is caused by otitis media, the nasal spray medication should be used along with the pro-discharge medication Cerno or Mucosolvan, and the amoxicillin capsule can be added.
