Sinusitis Infection – Causes, Symptoms, Treatment & Prevention

Sinusitis Overview

Sinusitis or sinus infection causes inflammation when sinuses that are behind the nasal cavity get infected. They can also cause swelling of the tissue lining the sinuses. Sinuses are part of the human anatomy and when they are healthy, they are filled with air. If somehow they get blocked, the natural drainage is affected. 

The sinuses can grow pathogens and cause an infection. The sinus cavity is divided into four paired spaces and the same are joined by narrow canals. 

The natural function of the sinuses is to make thin mucus and help drain out the same from the nose to keep the airway free of infection. See, the drainage is also a filtration system of the nose. 

The sinus infection can be of two types. It can be acute, which lasts for 5 to 6 days and resolves on its own or chronic sinusitis which is a long-lasting sinus infection.

Fast Facts on Sinusitis

Sinusitis is a common problem and generally gets resolved on its own. It does not require a doctor visit if a patient experiences benign symptoms. The common problems or symptoms that people face are runny nose, bad breath, or a headache. 

But, the condition should not be ignored. A thorough diagnosis is not going to hurt you. If you are suffering from a sinus infection, make an appointment with ENT doctors and get diagnosed.

There are cases where the sinus infection can cause severe headache or a feeling of pressure in the sinus cavity. In some cases, it can lead to toothache or ear pain.

What Causes Sinus infection

Sinus affects a lot of people every year. Sometimes, it can be caused by allergies or blocked nasal passage. Among the common reasons, swelling inside the nose, common cold, drainage duct blockage, structural differences, nasal polyps or immune system deficiencies are responsible for the occurrence of sinus infection. 

It has been noted that several medications that suppress the immune system can also lead to sinus inflammation and cause sinus headache or feeling of pressure around sinus. Besides, chronic sinusitis has a lot of triggers which entails factors such as blocked airways from asthma or allergies, an infection of the nose, fungus or deviated nasal septum. 

In kids, the sinus infection can be caused by allergies or illnesses from other kids at daycare or school. Besides, pacifiers also affect sinus in kids. Some kids get it if they drink water from a bottle while lying on the back. If you are a parent, you should keep your kids away from second-hand smoke as it can lead to infection of sinuses.

Types of Sinus Infections

Sinusitis can be classified in different categories such as viral sinusitis, bacterial sinusitis, allergic sinusitis, and chronic sinusitis.

Viral sinusitis

If a patient is experiencing cold-like symptoms including runny nose, sore throat, sneezing, nasal congestion, and coughing, then he might have a viral sinusitis. Besides, in the case of viral sinusitis, mucus may be clear, or slightly colored. 

Antibiotics do not work against viral infection, so the best treatment is to get rid of the symptoms of sinusitis is by getting as much rest as possible. A patient can consume fluids, use saline nasal sprays, and take over-the-counter pain relievers and oral decongestants. In general, sinusitis caused by a virus is cured in 7-10 days.

Bacterial sinusitis

If a patient has bacterial sinusitis, he may experience thick nasal discharge, swollen nasal passages, and dripping mucus from the back of the throat. Some patients of bacterial sinusitis also experience facial pain and pressure. These patients should immediately consult a doctor. 

The ENT doctor or sinus specialist may prescribe amoxicillin. Most patients of acute bacterial sinusitis respond to antibiotics with symptoms resolving in 10-14 days.

Allergic sinusitis

Allergic sinusitis can cause inflammation that leads to nasal congestion and swelling of the mucus membranes. The mucus can block normal sinus drainage. In most cases, allergic sinusitis leads to chronic sinusitis as symptoms are seasonal but may last for a year. 

A patient of allergic sinus infection complains about:

  • Sneezing

  • Itchy nose, throat, or eyes

  • Nasal congestion

  • Postnasal drip

  • Runny (clear mucus) nose

The allergic sinusitis can be treated with antihistamines. A person can avoid allergic triggers, and, in some cases, allergy shots.


An expert ENT doctor can help you figure out if you have sinusitis or something else. Also, the doctor can identify the reason for sinus infection. The ENT specialist can ask questions to discuss how long you’ve had sinus symptoms. The doctor can see if the symptoms are getting worse or improving. 

If you are experiencing symptoms from the last 10 days and they’re not getting worse, you might have a viral infection. It will go away on its own with time.

 The doctor may suggest over-the-counter treatments, acetaminophen, or ibuprofen or nasal decongestants. If you begin to use nasal decongestants, you have to read the directions carefully.
