What level of intervention is required for the patient experiencing swimmer's ear?

Swimmer's ear, or otitis externa, typically requires a focused assessment to determine the appropriate course of treatment. In this case, the selection of one resource for a physical exam is appropriate because it highlights the need for a basic evaluation of the ear to confirm the diagnosis. This examination may include inspecting the ear canal for inflammation or infection and assessing for any signs that would suggest the severity of the condition.

In instances of swimmer's ear, a detailed physical examination can often be sufficient to provide a clear diagnosis and to determine the necessary steps for treatment, such as cleaning the ear canal or prescribing topical antibiotics. This approach aligns with the usual practice in managing such conditions, where immediate surgical intervention or extensive investigations are not typically required unless complications arise.

Thus, understanding that a simple examination is often the first step in managing swimmer's ear emphasizes the appropriate level of intervention needed and the focus on clinical assessment over more invasive or resource-intensive approaches.
