Get exam: The treatment is dependent on the etiology. Impossible to determine without an exam Best to be seen, then you can get ride of the pain.

See a doctor : It's impossible to tell you what this is without a direct examination of your middle ear by a licensed doctor - see your GP, an ER doc, urgent care doc, or ENT for best results

Middle ear infection: See a MD, take course of oral antibiotics. Warm water rinses aren't going to help
