The TOP Remedies to Drain Your Sinuses

Sinusitis is an inflammation, or swelling, of the tissue lining the sinuses. The sinuses are four paired cavities (spaces) in the head. They are connected by narrow channels. The sinuses make thin mucus that drains out of the channels of the nose. This drainage helps keep the nose clean and free of bacteria. Normally filled with air, the sinuses can get blocked and filled with fluid. When that happens, bacteria can grow and cause an infection (bacterial sinusitis).
This is also called rhinosinusitis, with “rhino” meaning “nose.” The nasal tissue is almost always swollen if sinus tissue is inflamed.
