Ear Discharge is any fluid (blood, wax, pus) that comes from the ear. It is also called otorrhea. Most of the time, any fluid leaking out of an ear is ear wax. Ear infection is very common in babies and young children. Sometime some infection near the ear can cause ear discharge which can be cured it within 2-4 days. But if this discharge is irregular that means these is some trouble in ear drum.
