Sinuses are air-filled pockets that serve as small air-quality-control centers under your cheekbones, above your eyes and nose, and behind your eye sockets. It’s their job to help warm, moisten, purify, and generally condition the air you breathe before it hits your lungs. When your sinuses are functioning properly, entering bacteria get trapped and filtered out by mucus and minute nasal hairs called cilia.

Try these sinusitis treatment methods, which doctors say will help unstuff your sinuses, reduce pain and pressure, and get the air flowing freely.
