Ear infections are the most common cause of ear pain. When the ear becomes infected, inflammation and buildup of pressure cause pain that can be intense.People with ear infections often have other symptoms, such as sinus pressure or a sore throat because infections from nearby areas may affect the ear. An ear infection can also be a standalone condition. Most ear infections are bacterial, not viral. Ear infections are not as common in adults as they are in children, although they can be more serious. Middle ear infections are typically caused when bacteria or viruses from the mouth, eyes, and nasal passages get trapped behind the eardrum. The result is pain and a feeling of plugged ears. Some people may have trouble hearing, as an inflamed eardrum is not as sensitive to sound as it needs to be. There is also a buildup of fluid or pus behind the eardrum, which can make hearing more difficult. It may feel as if the affected ear is underwater.Dose:Squeeze 1-2 drops in affected ear once a day for 3 days. Apply it as needed.
