Which part of the ear?
Ear infections may affect different parts of the ear. Otitis media refers to the middle ear; otitis externa affects the outer ear canal. The location and cause matter when deciding on treatment. The NHS guide to ear infections covers both types.
What you may notice
Ear pain, fever, pressure, discharge or a change in hearing can occur. Young children may be irritable or pull at an ear. A professional may examine the ear with a lighted instrument called an otoscope.
When to seek advice
Get prompt medical advice for swelling around the ear, discharge, new hearing loss, dizziness, a high fever or feeling very unwell. Seek advice if symptoms are not improving after three days, infections recur, or you suspect an infection in a baby under 12 months. People with a weakened immune system or certain long-term conditions may need earlier assessment.
If an infant has a high fever or seems very unwell, call 911 or your local emergency number now.
