Some people don't notice any symptoms of a ruptured eardrum. Others see their doctor only after several days of general discomfort in their ear and feeling that "something's not quite right with the ear." Some people are surprised to hear air coming out their ear when they blow their nose. Forcefully blowing your nose causes air to rise up to fill the space in your middle ear. Normally this will cause the eardrum to balloon outward. But if there is a hole in the eardrum, air will rush out. Sometimes the sound is loud enough for other people to hear.
