Acute Sinusitis: Causes, Symptoms and Treatments

Acute sinusitis is a common condition, particularly during cold months or after a cold. Although often benign, it can cause significant discomfort. Here is everything you need to know to better understand this condition and effectively relieve its symptoms.

What is acute sinusitis?

Acute sinusitis is an inflammation of the paranasal sinuses caused by a viral infection, bacterial infection or, more rarely, by an allergy. It often occurs after a cold or an upper respiratory tract infection and prevents mucus from draining properly, leading to uncomfortable symptoms.

Main causes

• Viral infections: responsible for the majority of acute sinusitis cases, these often appear after a cold.

• Bacterial infections: less frequent, these can develop when trapped mucus promotes bacterial growth.

• Allergies: these cause inflammation and blockage of the sinuses.

• Aggravating factors: smoking, pollution, or anatomical abnormalities (deviated nasal septum, polyps).

What are the symptoms of acute sinusitis?

Common signs include:

• Facial pain or pressure around the eyes, nose or cheeks.

• Nasal congestion or thick discharge, often yellow or green.

• A decrease or loss of smell.

• Mild to moderate fever.

• Fatigue and general malaise.

• Headaches, sometimes more intense when leaning forward.

When to consult a doctor?

Although viral acute sinusitis generally resolves within a week, some cases require a medical consultation:

• Symptoms that persist or worsen after 10 days.

• High fever (> 39°C).

• Swelling or redness around the eyes.

• Intense and localized facial pain.

• History of chronic sinusitis or complications.

How to treat acute sinusitis?

1. Supportive measures

• Rest: This is essential, especially at the beginning, to help your body fight the infection. Slightly elevate your head when lying down to reduce congestion.

• Stay hydrated: Drinking plenty of fluids, especially hot drinks, helps thin secretions and soothe the nasal passages.

• Increase humidity: Use a humidifier or take a hot shower to clear your sinuses.

• Rinse your nose: Saline sprays or Neti pots can promote mucus drainage.

• Gargle: Prepare a homemade saline solution with half a teaspoon of salt dissolved in a glass of lukewarm water, and use it to soothe the throat if irritated.

2. Over-the-counter medications

• Nasal decongestants: Products containing oxymetazoline (such as Otrivin) temporarily relieve congestion but should not be used for more than three days to avoid rebound congestion.

• Analgesics: Acetaminophen or ibuprofen can reduce pain and inflammation.

• Caution with antihistamines: These are not recommended unless there is an allergy, as they do not effectively relieve cold symptoms and can cause adverse side effects.

3. Antibiotics

These are only necessary in cases where a bacterial infection is confirmed or strongly suspected, particularly if symptoms are severe, persistent or worsening.

Preventing acute sinusitis

• Wash your hands frequently: This limits the viral infections responsible for the majority of sinusitis.

• Rinse your nose regularly: Use a saline solution or a Neti pot to keep nasal passages clear and reduce mucus accumulation.

• Avoid smoking: Tobacco irritates the nasal mucosa and promotes infections.

• Manage your allergies: Treat your allergies with antihistamines or nasal corticosteroids if necessary to prevent chronic inflammation of the sinuses.
