Deviated septum?

[hmmm167]

I have been having chronic problems with post nasal drip and pressure on the bridge of my nose. It's not terribly bothersome, rather annoying. Let me explain what I mean by post nasal drip. I feel like there is constantly mucus stuck in the back of my nose. It isn't really dripping down my throat, rather just sitting in the back of my nose. It feels thick and I often have to snort in order to get it out. It is not discolored, just clear/milky white. I also have a bump on the bridge of my nose, which is where the pressure occurs. I'm wondering if I have a deviated septum. Are these even symptoms of a deviated septum? I haven't yet seen a doctor and am wondering if it is even necessary. I'm kind of used to it, but it would be nice to have a solution.
Other pertinent information: I had my tonsils removed about 4 years ago due to frequent sore throats. I remember coughing up those disgusting, smelly tonsil stones quite frequently. I did hit the bridge of my nose a few months ago with a car door. It was swollen and bruised for several days, but my symptoms occurred prior to that incident. Besides that, I have not had any blunt trauma to my nose. I haven't really had problems breathing, but I do get frequent, mild stuffy noses; sometimes just on one side. I have woken up before gasping for air, but only 2 or 3 times throughout my life. I'm 26 years old and am not over weight. Thanks in advance for your help.

I'm actually not a milk drinker and don't eat much dairy. But thanks :) And I do try to drink a lot of water throughout the day.

You may get relief from the thick mucus if you stop drinking milk and decrease all dairy.  Eggs are not dairy, BTW.
