How can I ease ear pain at night?

Etiology. Ear pain or otalgia is not necessarily the result of ear disease. If your hearing is essentially normal, the most common cause of otalgia is disease of the dental structures, jaw muscle spasm, dental infection, arthritis of the jaw joint. Other causes of referred pain can reflect diseases of the neck (cervical arthritis) or diseases of the throat or even larynx. Easing pain requires a diagnosis.
