It could be sinus related as that is how my face feels when I have a bad sinus infection.

The TN that I have experienced is nothing like sinus discomfort. How can I put it . . .if I ever, ever call a doctor during non working hours (oh heck, I hate calling during business hours. LOL) something is wrong. When I had TN, I called on a Saturday. It was painful, definitely nerve as well as you could see the muscles in my face in spasms. I couldn't eat, drink, talk, or really do anything that involved the face. Very different than sinus issues that I have experienced.
