Just thought i would come back to the forum and post my results. About a week after I posted I was at work and all of a sudden i felt a rush of fluid down my throat and in my nose. My sinuses had drained. Then, no matter what i tried, i couldn't bring that pain back to my temple. A few days later the pain was back a little, and then the same thing happened. My sinuses drained and no more pain. So for most of you, a sinus infection is probably the culprit. If you are worrying about it get it checked out by a doctor or dentist and they can tell you. No temporal arteritis, no TMJ, no tension headache, no cancer, no HSV1, just a simple sinus infection.
