Post Nasal Drip, Pressure On Bridge Of Nose. Deviated Septum?

I have been having chronic problems with post nasal drip and pressure on the bridge of my nose. It's not terribly bothersome, but it is kind of 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. 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 curious if it sounds like I have a problem.
