Foreign bodies in the external auditory canal: such as beans and other plant foreign bodies can swell when exposed to water, blocking the external auditory canal, causing a stuffy feeling in the ear, hearing loss or ear pain and other manifestations, which can cause otitis externa. 2. Otitis media: secretory otitis media, mostly caused by upper respiratory tract infections, clinical manifestations of tinnitus, ear pain, hearing loss, and ear stuffiness, etc., stuffiness or occlusion of the ear, may be temporarily alleviated by repeated pressure on the ear screen. 3. Fungal disease of the external auditory canal: when the external auditory canal accumulates secretions or enters water, it is susceptible to fungal infections, causing itching and stuffiness in the ear, which seldom causes earache. The tympanic membrane and the external auditory canal can be seen to be covered with white or yellowish-black fungi. It is recommended to seek immediate medical attention to clarify the cause of the ear infection, and then treat the cause and symptoms.
