A ruptured eardrum does not hurt all the time, but there are two clinical situations in which a sudden rupture of the eardrum may occur: in the first case, in patients who have a sudden perforation of the eardrum after trauma, there may be significant pain in the eardrum at the time of the trauma, but after a period of time, the pain will gradually ease. If the pain persists and gets progressively worse, this suggests a possible local infection, as infection can easily lead to ear inflammation and thus pain. In the second case, some patients, especially infants and children, have acute otitis media, where a large amount of purulent secretions are retained in the tympanic chamber, squeezing the eardrum and causing significant pain. If the patient has pain all the time after the eardrum is broken, it is recommended that the patient needs to go to an outpatient clinic to check the tympanic membrane like situation and improve the related examination to exclude other diseases.
