Yes, it might be. The sore throat is almost certainly being caused by nasal drippage, and the sneezing is related. And the fact that I'm not coughing (most of my colds move into my chest and take up long-term residence as bronchitis) reinforces this possibility. I guess I could research what pollens are in the air. Could be something about my new office -- the trees in the canyon on which it sits may be producing something my body doesn't like. That would be a heck of a thing -- being allergic to my office.
