Which of the following is a typical symptom of otitis externa?

Otitis externa, commonly known as swimmer's ear, typically presents with specific symptoms related to the ear canal. Ear tugging is a classic sign, especially in children, as it indicates discomfort or irritation in the ear. This behavior is a response to pain or discomfort that occurs when the ear canal is touched or moved, which is characteristic of otitis externa due to inflammation and infection of the ear canal lining.

While other symptoms such as pain or itching in the ear are more common, ear tugging explicitly represents a direct behavioral response indicating discomfort associated with this condition. Signs like jaw discomfort or swelling around the ear might also be noted, but they are less specifically indicative than ear tugging.

In contrast, painless swelling might suggest a different condition, such as a benign cyst or another type of infection. Impaired vision is not associated with otitis externa as it pertains to a different anatomical area. Similarly, facial swelling could stem from a more serious condition like cellulitis or an allergic reaction, which is not typical for uncomplicated otitis externa. Overall, ear tugging directly links to the discomfort typically felt in otitis externa and serves as an important clinical sign in its diagnosis.
