What can cause puss to come out of the ear if no ear infection is present?

Pus coming from the ear, even in the absence of an ear infection, can be caused by several factors, including a ruptured eardrum, which can lead to fluid accumulation, or the presence of earwax buildup that can become infected. Allergic reactions or skin conditions like eczema can also result in discharge. Additionally, foreign objects lodged in the ear can irritate the canal and cause pus formation. It's important to consult a healthcare professional for a proper diagnosis and treatment.
