Can you have allergies, but not "show" it?

So I finally went to an ENT doctor and got a CT scan done of my sinuses.  The results show some good results (not too much blockage of the sinuses), but other, not-so-good results: a deviated septum.

My septum looked like a maze or some **** on the scan.  It looked to me like it was severely deviated or something.  The nurse even gasped when she saw it.  The doctor didn’t say too much about it, however.

What he was concerned about was some swelling on both sides and he recommended allergy testing as the next step.

The thing is, though, I’ve never thought of myself as having allergies.  I mean, when I think of someone with allergies, I think of the person who is always sneezing, is congested, and has watery/red eyes – I have none of those symptoms.

Can one have allergies, but not have those tell-tale signs?  I mean, I rarely sneeze, don’t have yellow or green mucus (unless I’m sick), and generally feel okay.

I’m hoping that I do have allergies, however, and that it is the cause of the swelling.  Any thoughts?

Generally, the mucus that comes out of my nose is clear or sometimes whitish in color.
