CAUSES OF SINUS CONGESTION AND PRESSURE
Your sinuses are four pairs of air-filled spaces connected to your nasal passages. When working normally, the sinuses help humidify air as you breathe in and produce mucus that helps trap bacteria and foreign particles (like pollen).
But when nasal passageways become blocked (often due to irritated tissues), mucus that normally drains away can build up. Swollen nasal passages and mucus build-up are the usual causes of sinus congestion and pressure.
WHICH SINUSES ARE CAUSING YOUR SINUS PAIN?
in your forehead, vary greatly in size
behind your nose and between your eyes, about the size of a matchbox
behind your cheekbones, between the bottom of your eyes, and the top of your upper jaw, about the size of a large walnut
deep in your head behind your nose, about the size of a large grape
SYMPTOMS OF SINUS CONGESTION
Sinus congestion and pressure are difficult to ignore. The feeling of “fullness” is caused by the blockage of sinuses, as opposed to nasal congestion. Most feel the blockage in the cheeks and often find it difficult if not impossible to breathe through their nose.
