Re: sinus infection for 2 years
Chronic sinus infections are usually caused by some type of physical blockage of one or more of your sinuses that keep the sinus from draining correctly (which creates a perfect breeding ground for bacteria). Generally the physical blockage is a deviated septum, nasal polyps or inflammation (which can be caused by allergies, some type of environmental irritant or even GERD).
Your best bet would be to see and ENT for a CT scan to try to identify which of your sinuses isn't draining correctly and why. In some cases nasal irrigation combined with a nasal steroid spray can clear up the inflammation so your sinuses drain correctly. If that doesn't help the doctor may recommend oral steroids or, as a last resort, surgery to correct the blockage.
