What Are the Causes of Sinus Irritation & Drainage?
Sinus irritation and and the drainage that often accompanies it are nuisances and, if not taken care of in a timely manner, can become acute or chronic problems. Called sinusitis, sinus irritation that has led to inflammation and swelling of the nasal cavities inhibits normal mucus flow. According to the Mayo Clinic, this buildup of excess mucus is a feeding frenzy for bacteria in the sinuses; an infection can easily take hold and cause discomfort for the sufferer. Preventative measures can be taken if the causes of sinus irritation and drainage are understood.
