A sinus infection, also known as sinusitis, occurs when the sinuses in the nasal cavity become inflamed and infected. Sinuses are air-filled cavities located within the bones surrounding the nose. When they become blocked and filled with fluid, bacteria, viruses, or fungi can grow and cause an infection.

Causes and Symptoms

Sinus infections are commonly caused by a viral infection, such as the common cold. Other causes include allergies, bacterial infections, and structural abnormalities in the nasal cavity. Symptoms of a sinus infection may vary but often include:

  • Facial pain and pressure

  • Nasal congestion

  • Thick nasal discharge

  • Cough

  • Headache

  • Fever


The treatment of a sinus infection depends on its cause and severity. In most cases, sinus infections caused by viruses will resolve on their own within a week or two. Self-care measures can help relieve symptoms, such as:

  • Using saline nasal sprays or rinses

  • Applying warm compresses to the face

  • Drinking plenty of fluids

  • Getting adequate rest

If the infection is bacterial or persists for more than 10 days, a doctor may prescribe antibiotics to help clear the infection. Over-the-counter pain relievers and decongestants may also be recommended to alleviate discomfort and congestion.


While sinus infections cannot always be prevented, there are certain measures that can reduce the risk of developing an infection. These include:

  • Practicing good hand hygiene to prevent the spread of viruses and bacteria

  • Avoiding known allergens that trigger sinusitis

  • Keeping the nasal passages moist with saline sprays or rinses

  • Quitting smoking or avoiding exposure to smoke

  • Using a humidifier to add moisture to the air

When to See a Doctor

It is advisable to consult a doctor if symptoms of a sinus infection persist for more than 10 days, worsen over time, or are accompanied by severe headache, high fever, or changes in vision. A healthcare professional can assess the condition, identify the underlying cause, and recommend appropriate treatment.
