If the ear feels like it is blocked but you can hear, cerumen embolism and secretory otitis media are clinically considered. In the case of cerumen embolism, the blocked outer ear canal is blocked, so you can feel the stuffy feeling in the ear but still hear it. In contrast, secretory otitis media is mostly caused by upper respiratory tract infection, which can cause congestion and swelling of the mucous membrane in the nasopharynx, resulting in air not entering the tympanic chamber from the eustachian tube, leading to ear stuffiness, just like being blocked, and hearing is also affected, but can be heard. Treatment requires 1% furosemide drops to reduce the congestion and swelling of the mucous membrane of the eustachian tube and facilitate the entry of air into the tympanic chamber, and antibiotic applications such as cefprozil orally to reduce the congestion and swelling of the mucous membrane of the eustachian tube and facilitate the recovery of the disease, with the addition of hormones such as prednisone if necessary. After the above treatment, the above symptoms will be effectively controlled until cured.
