Ear pain and hearing loss are mainly seen clinically in the following diseases: 1. Acute otitis externa, when patients with acute otitis externa have significant swelling of the ear canal, they will experience hearing loss because sound conduction does not go in, mainly with a painful sensation in the ear, accompanied by hearing loss mainly. 2. Acute secretory otitis media, which is a little more common in children, patients can experience ear pain because of the presence of lesions such as fluid accumulation in the tympanic chamber. This causes hearing loss in patients, mostly secondary to diseases such as upper respiratory tract infections. 3. Individual patients are suffering from pain caused by blockage of earwax, as it is also possible that the blockage of earwax leads to hearing loss in patients afterwards. When there is an acute attack of chronic purulent otitis media, a large amount of pus accumulation in the ear canal, and local infection in the ear canal, a painful sensation in the ear canal can occur because of the presence of tympanic membrane perforation and inflammatory lesions in the tympanic chamber, so the patient has hearing loss, etc. All in all, if a patient has this condition, it is recommended to go to the ENT department for an otoscopy, along with a hearing examination and, if necessary, a CT examination.
