Sinusitis: Sounds like an antibiotic may be necessary. Try using sterile saline nasal irrigations twice daily and get plenty of sleep to enhance your immune function.

Xylitol: Xylitol is a natural sugar and breaks up biofilm in the body. That's where germs mulitply. It is found in a nasal spray called xlear (pronounced "clear") and in chewing gum called spry. Pleasant tasting too! See doc for diagnosis first.
