Is there a common cause that can lead to a pain in the ear and throat when swallowing?

Seedentist/physician: If both of your lymph nodes under your ears along your need are tender, start with your physician . If he/she does not find anything ( ear infection, strep throat) to treat be sure to have them look in your mouth. See your dentist. You could be having a problem with wisdom teeth or you have facial pain being referred from you jaw joints to your neck.
