Is the area under the ear and right behind the jaw swollen and tender? Just clenching your jaw at night can make a lot of pain. I went to an ear specialist and he was wonderful! He gave me the phone number of a massage therapist that does gentle massage for both sides. It was wonderful and now I don't need it. I know what it is now if it happens and I can massage it and put a little heat from a rice filled sock and they are great.
