Hi F.,
Your situation sounds a lot like my experience. After chronic sinus infections for years (5 or so/year), I finally saw an ENT (Otolarynologist and head & neck surgeon) who discovered my deviated sceptum. I had the surgery performed, and it has made a big difference. The recovery from the surgery was not the easiest I could have imagined, but after a few weeks of kind of a constant headache, it started to lift and I finally felt like I could breathe well for the first time. Even after the surgery my doc said my sinus passageways are still very narrow. When you have a blockage, it just makes it so easy for a little bit of something to get caught in there and start to fester. So, like the other person who responded, I use a sinus rinse - it is called Sinus Rinse by NeilMed. This makes big difference. It's no picnic to rinse out your sinuses every day but in the long run it really helps. Also, it's important to keep your sinuses moist throughout the day (this is especially important in the winter) by using a saline spray (no chemicals/drugs) - I use something called Simply Saline. Both things are available at drug stores, usually CVS carries them for sure. A last resort is a prescription sinus spray like Rhinocort which helps to shrink swelling in the tissue and promote a more open passageway. Yes, it's job in itself but not being on antibiotics 5x/year is worth it! Let me know if you would like a referral to the surgeon I saw. He is very good and highly experienced.
