Last couple of days I've noticed pain in my nose, specifically pressing on the sides of the left or right nostril. The pain seems most pronounced towards the base of my nose above the lips (as opposed to the nose tip).
I had a root canal done when I was eighteen on my front right incisor, but pressing on the area above that tooth is pain free. Only when I push on the nostrils do I get the pain. Weird. I'll let it go another day or two, then off to a doctor.
UPDATE 8/5/12
Pain has disappeared. I suspect somehow my sinuses were involved. Glad that's over!
