Muse,<br/><br/>One of the best things you cn do is buy a sinus irrigation kit from a drugstore.  It will feel absolutely eerie, but blushing your nasal cavitiy with warm salt water will help you more than you will believe possible.<br/><br/>I recommend NeilMed, they make a good one.  SaltAire works well, but the solution is premade and costs a lot more.  NeilMed is jsut easy to mix, put a apcket of mixer in the bottle, fill with body temperature water, shake and hose your nose!
