I get allergy related or seasonal migraines. Mine are in connection with my sinuses. Sinuses can not only affect your head but can affect your jaws and teeth as well. I would think they can affect your ears as well. Is probably why I get some occasional soreness as well. Hmm. Anyway, I will sometimes even get gum swelling, usually just on my right side, if I am having sinus trouble. It's crazy. But back to the migraines. I hope you can get some definitive answers. Getting on an allergy medication, one of the 24hr OTC ones may help. Down here, the pollen from the trees have been making me aware of allergies that I didn't even know I had. I've been having reactions in ways that is not normal for me. Go figure that one! It's been awful here lately. I hope it is something simple like that for you.
