Bacterial Infection
"Have had sinus infections, at least twice a year, for over 24 years, Starts out as coughing &amp; phlegm but within two days you can feel the difference between a regular cold &amp; an infection in the chest area.  That&#039;s when what you cough up turns from clear, light green to thick tan/beige.  

Have had quite a few meds over the years, including Cleocin HCL 300 mg (this goes in a large Ocean Mist spray - works well). The doxycycline works the best but you MUST follow the directions.  One cap by mouth twice daily for ten days.  And TAKE WITH FOOD.  If you don&#039;t you will get the nausea &amp; stomach upsets."
