CONGESTION
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).
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?
Frontal
in your forehead, vary greatly in size
Ethmoid
behind your nose and between your eyes, about the size of a matchbox
Maxillary
behind your cheekbones, between the bottom of your eyes, and the top of your upper jaw, about the size of a large walnut
Sphenoid
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.
TIPS FOR SINUS CONGESTION RELIEF

Drink water.
Water may help thin mucus, and thin mucus is more likely to drain. When you feel your sinus problems beginning, start hydrating.

Steam your sinuses.
The extra moisture helps keep nasal passages moist and helps with drainage. Anything from a hot shower to carefully inhaling steam from boiling water can help you feel better.
