Itchy ears can be a symptom of an ear infection. Depending on the type of pathogen that causes the infection,
ear infections can be bacterial, viral, or fungal. Otitis externa or outer ear infection is one of the most common forms, and it causes significant ear pain as well as itching in the ear canal. This condition is also known as swimmer's ear. It can happen when water gets trapped in your ear canal after swimming.
Otitis media impacts your middle ears and causes similar symptoms to otitis externa. Children suffer from this the most, because of frequent colds and blocked Eustachian tubes.
With fungal infections, the itching tends to be more intense. Aside from that, it's quite difficult to tell which type of ear infection you are dealing with. Doctors often start by prescribing an antibiotic, and if the treatment fails, then they assume that the infection may be fungal.
