An ear discharge is drainage of blood, ear wax, pus, or fluid from the ear.
Most of the time, fluid leaking out of an ear is ear wax. (For more information of this topic, see the article on ear wax.)
However, discharge may also be caused by minor irritation or infection. A ruptured eardrum can cause a white, slightly bloody, or yellow discharge from the ear. Dry crusted material on the child's pillow is often a sign of a ruptured eardrum.
Bleeding from the ear may also be due to injury, cancer, or a foreign object in the ear canal.
