Sinus pressure infection is a clear sign of sinus infection. When foreign substances penetrate the physiological system of a human being through nasal corridors, they cause the sinus membrane to be disturbed and thus causing inflammation. As a result of the swelling, the sinus entries are obstructed and resultant blocks and stifling of the nasal corridor ensues. The sinus cavities accumulate confined gases, mucus and puss. This can be a cause for intense pain and anguish.
The sinus cavities present in four pairs. Namely,
Frontal sinuses – which are placed in the forehead, just above the eyes.
Maxillary sinuses – which are held on both sides of the nose in the cheekbone.
Ethmoid sinuses – which are found at the back of the bridge of the nose and located between the eye cavities at the basal area of the nose.
Sphenoid sinuses – which are located at the back of the eyes and thus the ethmoid sinuses
These sinus cavities are endowed with an aperture each, called the ostium. These apertures have openings into the nasal corridors and facilitate the passage and exchange of mucus and air. The mucous linings in the sinus cavities are in continuance with the mucous linings of the nasal corridors. The cilia are cells on the mucous linings which are filters which allow the mucous to pass through the sinus cavities onto the nasal passages. The sinus cavity, if blocked, might hold unreleased air and secretions and in turn exert pressure on the walls of the sinus and are the chief sources of pain in course of a sinus attack.
Virus, fungi or bacteria are the chief culprits of sinus infection. Sinus pressure is mostly a result of infection of the sinus and allergy. If these germs affect the nasal membrane, which is often the case, they become irritants causing the sinus membrane to swell up. Air, pus and mucus find entry into the sinus cavity if there is inflammation. This enhances pressure within the cavity. Sinus pressure is often stepped up even when there are allergic reactions to pollen, pollution, particles of dust or chemical irritants present in the air in general. This also becomes a definite source of irritation and inflammation which steps up sinus pressure in turn.
When sinus infections in turn leads to sinus pressure enhancement, often precautionary steps are advised. To look at this way, sinus infection is not entirely avoidable, but, the impact of the attacks can be controlled. Wherever, sinusitis or sinus infection leads to sinus pressure infection antibiotics, decongestants, nasal sprays and pain killers come in handy. In case of an allergy attack causing sinus pressure inflammation, get required allergy tests done and the cause and source of allergy has to be strictly avoided for comfort.
