Blocked Sinuses Remedy Link Guide

Blocked sinuses—medically known as sinus congestion or rhinosinusitis—occur when the tissue lining the sinuses becomes swollen or inflamed. This inflammation narrows or fully obstructs the tiny drainage passages (ostia), trapping mucus and air. The result is that familiar, miserable pressure behind the cheeks, eyes, and forehead, often accompanied by headache, post-nasal drip, and a diminished sense of smell.
