The presence of a cough accompanied by pain in the right ear is most commonly associated with the clinical appearance of inflammation of the right ear canal, also known as otitis and otitis media. The most common clinical cough is airway inflammation, which is commonly caused by a decrease in the body’s immunity and an inflammatory response in the mucosa of the upper respiratory tract following infection by viruses, bacteria, and other pathogens. The mucous membrane of the upper respiratory tract is obviously congested and edematous, with inflammatory secretions exuding. The mucous membrane of the airway is interconnected, especially with the ear canal through the eustachian tube, and at this time the inflammation spreads, causing inflammation through the eustachian tube and finally reaches the ear canal, causing otitis and otitis media, and the inflammatory factors secrete in large amounts and then stimulate the nerves of the ear canal, causing symptoms of ear pain.
