I agree with Roxanne. I perform nasal irrigation daily with a salt water mixture (8 oz filtered water and 1 tsp sea salt) and I haven't had ANY sinus problems since. Be forewarned that the first week or so of performing the irrigation you may feel burning in your sinuses. This was quite painful for me the first two days. But it quickly faded and now I don't feel anything other than the tickling sensation of the water in my nose. Also, never force the water out after you're done or you could force water into your eustacian tubes, and infection, etc. could ensue.
