10 Causes of Itchy Ears
Cause #2: Infection
Infection occurs when there is invasion of the tissues by pathogens, which then multiply and cause host tissue reactions to the pathogens and toxins produced. Infections are caused by pathogens such as viruses, bacteria, prions, parasites, and arthropods. The host then fights the infection using the immune system. This often involves inflammation, which is then followed by an adaptive response.
Medications that can be used to treat infections depend on the pathogen that caused the infection. Itchy ears can sometimes be due to an ear infection, especially when one has flu.
