Micah, I had my sinus' bored out when they repaired a deviated septum. All of it was based on the sizes and locations of the "drains" (for the lack of a better term) in the sinus cavities. Everybody's sinus' are different. Mine had relatively small drainage holes and some are not at the lowest point in the cavity, trapping mucus and/or seawater (with all it's little micro organisms) in certain sinus cavities. I don't dive as much as I used to, but it's still part of my job and sinus infections from saltwater were definately common.
The "roto-rooter" and sinus flushes definately help. The flush is basically the same as a neti-pot, but you don't have to crank your head to the side. I think NeilMed makes both.
Wrong thing to do? Did you lose your sense of smell?
I think the actual term isw FESS http://en.wikipedia.org/wiki/Functio..._sinus_surgery
But seriously did you lose your sense of smell.....
I had "nasal" polyups a few years ago, and like most guys I put off going ot the Dr forever. When I finally went he said I was 100% blocked on one side, and 98% on the other! I don't know if that is what your situation is making the sinus infections worse, but with this condition you have an allergic reaction (mine was dust) and the membraines in your sinus get inflamed. When the membraines are inflamed, your natural tendency is to blow your nose, but with an alergic reaction it is not caused by mucus, but by the membraines in the sinus cavity being irritated. Long/short, blowing your nose does nothing to alleviate the problem, and by blowing your nose you create polyups. You have 8 sinus cavities on each side of your head, and when you force blowing your nose, the polyups build in the back and eventually work their way close to your nose.
I had heard horror stories about the surgery (ripping you open, long recovery, etc). However, my doctor used a method where they basically snaked something down your nose and conducted the surgery looking at a video screen. I was 100% back to normal within 3 days, and back to work in 2. Just go to the doctor and get it checked out, if it is polyups its an easy fix. Good luck!
