Sinusitis, commonly known as a sinus infection, occurs when the sinuses become swollen and inflamed. This condition can result from various factors, including colds, allergies, structural issues like a deviated septum, and more. It’s essential to distinguish between the different types of sinusitis, such as acute and chronic, and understand their respective causes and symptoms.

Acute sinusitis often follows a cold and lasts for a short duration, typically 7 to 10 days. In contrast, chronic sinusitis is a long-term condition that may be triggered by allergies to substances like dust, mold, or pollen. Symptoms of a sinus infection include painful pressure, congestion, and in some cases, infection.

Several factors can contribute to sinus blockages and subsequent infections. These include environmental irritants like cigarette smoke, changes in barometric pressure, nasal polyps, and structural abnormalities such as a deviated nasal septum.

People with allergic rhinitis or asthma may be more susceptible to chronic sinusitis, which can stem from infections, allergies, fungal growth, or, in rare cases, immune system deficiencies. Nasal polyps or structural problems in the nasal passages also contribute to chronic sinusitis.

Sinus infections can be contagious, and it’s important to differentiate their symptoms from those of other conditions like COVID-19. While sinus infections typically present with facial pain and pressure, COVID-19 symptoms often include fatigue, cough, shortness of breath, and sometimes gastrointestinal issues.

If you suspect a sinus infection, it’s advisable to consult a doctor for an accurate diagnosis and appropriate treatment. Treatments may vary based on the underlying cause of the sinusitis and its severity.
