Sounds like an infection of one sort or another. I had one in the eye that also caused similar symptoms to a sinus infection. The only difference was that there was no pressure when I tapped myself along the line of my cheekbone. (That's my major indicator of sinus infections, but that may just be my own weird thing, LOL!)

Gotta love the connections of nose, eyes, and ears when one of those goes out of whack. Hope you feel better soon.
