Quote from hp8:

Can you have allergies with just symptoms of congestion, no runny nose, no dry eyes, or rashes.

Yes you can, ask your doctor for a sample of singulair and perhaps one of those nasal sprays like Nasacort AQ. Flonase and Nasonex dry you out somehow and that's the last thing you want when you have a congested nose, Nasacort AQ it great when it comes to dealing with congestion and it does not dry you out like the other nasal sprays.
