what causes a busted eardrum
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. When that happens you may suddenly notice that the pain and pressure you've felt from the infection suddenly stops and pus drains from the ear.
