Get yourself tested for allergies. You might have them and not know it. If you've been tested years ago, they might have changed since then (it's normal). It might start out as a small cold / runny nose, that cascades into sinus infection, chest cold and goes from there. And it can be caused by almost anything - e.g. you might have mold in your house and not know it. It can affect your sleeping and everything else about your life. Also they're completely treatable by many means (from cheap/less effective to expensive/most effective): 1. avoiding whatever causes the allergy, 2. OTC medicine 3. perscription 4. shots 5. sublingual immunotherapy (slit) http://allergies.about.com/od/allergyshots/a/slit.htm http://allergies.about.com/od/allergyshots/a/slit.htm My wife got on the slit therapy and went from having 6 mystery sinus infections a year to now being healthy all the time. It's changed her life.
