Sinus blockage can stem from a variety of environmental, anatomical, and genetic causes, but swelling of the nasal passages often instigates the condition. This swelling is primarily induced by the common cold or allergies. More severe cases of sinusitis may result from structural issues such as a deviated septum, which is a misalignment in the partition separating the right and left nasal cavities.

So, what exactly sparks sinusitis? This condition is typically an infection triggered by viruses or bacteria, or a combination of both. Cold viruses and bacteria that invade our sinuses usually don’t pose a problem unless the sinus drainage is obstructed. The main reason we suffer from sinusitis is due to the blockage of the narrow sinus draining channels, and the key to treatment lies in the restoration of proper drainage.

Initially, to alleviate sinusitis symptoms, one might experience similarities to those of a cold, including fatigue, cough, an impaired sense of smell, fullness or pressure in the ears, or headache. As your body combats the infection, employing nasal rinses, decongestants, and pain relievers can help mitigate discomfort.

Distinct symptoms like bad breath, fever, lethargy, and loss of smell or taste may also manifest. Ear pressure is another common complaint. Sinus infection symptoms can diverge from those of a cold and if your symptoms progress instead of resolving in 7 to 10 days, it may indicate a sinus infection.

Chronic sinusitis is characterized by persistent inflammation of the sinuses. These moist air spaces, situated behind the bones of the upper face, typically drain through small openings into the nose. An obstruction of this flow can lead to an accumulation of mucus, further exacerbating the condition.

The most frequent cause of sinusitis is a viral infection such as the common cold. It can also arise following an upper respiratory infection (URI) or a common cold that doesn’t seem to subside. This leads to inflammation of the nasal passages which can severely obstruct the opening of the paranasal sinuses, resulting in repeated cycles of infection and inflammation.
