Question

Kate Bradley, age 22, is an avid swimmer. She swims year-round at least 2 days per week. Kate has an extensive history as a young child of repeated ear infections. She even had surgical placement of polyethylene tubes (PE) twice in her younger years to help decrease her frequent ear infections. Lately, Kate has developed left ear pain. She does not have an increased body temperature but notices an increase in left ear pain upon movement of the pinna. She thinks the outer ear looks a bit swollen but doesn’t notice any drainage coming from the ear. Kate also has noted a couple of instances where her balance has been impaired. She calls her practitioner and makes an appointment to have her ear checked.
