Since late on Thursday night, I've been experiencing intermittent pain in my jaw around my upper molar area. The pain radiates from my ear to right above my upper molar. It, also, extends to my lower jaw on the same side. I have had an ongoing problem with sinus congestion, but as of late, it seems to have gotten much better. However, in the past couple of days, I've become congested, again. Could this have anything to do with what's going on?
