After getting a cold couple months ago, ended up with sinus congestion.
Now after taking nasonex and then nasacort for 4 weeks, still feeling stuffy.

My family doctor is sending me to an allergist. But I've never had runny nose, irritated eyes, etc before. How can I have allergies. He said it can creep up on you slowly over time.

So is it possible to be allergic to something and just get sinus congestion?
