Been home the last two days with a severe sinus attack. Raw sinuses, nasal drip, coughing , sneezing---fun stuff. Finally felt a little better and did a little surfing and learned about nasal flushing. It involves flushing pollens, dust and other irritants out of your sinuses with a warm saline solution. It's a little awkward and a little gross but it seems to be helping tremendously. Just Google "sinus flushing".
