Call a doctor immediately if you suspect you or someone you know has a ruptured eardrum and any of the following occur: 1  An uncontrolled spinning sensation. 2  Difficulty walking. 3  An abrupt change in hearing.  A change in the ability to taste 1  foods. You accidentally put your ear under water.
A number of things can cause the eardrum to rupture; one of the most common causes is an ear infection. When the middle ear is infected, pressure builds up and pushes against the eardrum. When the pressure gets too great, it can cause the eardrum to perforate.nother common cause of a ruptured eardrum is poking the eardrum with a foreign object, such as a cotton-tipped swab or a bobby pin that's being used to clean wax out of the ear canal. Sometimes children can puncture their own eardrum by putting objects such as a stick or a small toy in their ear. 1 | 2 | 3.
