What Is Sinusitis?

Sinusitis refers to the inflammation or swelling of the tissue lining the air-filled cavities inside your face — located behind your forehead, cheeks, and eyes.
Normally, these sinuses help filter and humidify the air you breathe. But when they become blocked due to infection or allergy, mucus accumulates, leading to pain and congestion.

According to the Saudi Ministry of Health, sinusitis is often caused by viral or bacterial infections, persistent allergies, exposure to pollutants, or a deviated nasal septum.

To learn more about these sinuses and their functions, you can read our comprehensive article about sinuses.

 

Types of Sinusitis

Acute Sinusitis

• Lasts less than four weeks.
• Often triggered by a viral infection after a common cold.
• Common symptoms include facial pain, nasal congestion, and thick discharge.

Chronic Sinusitis

• Persists for more than 12 weeks, even with treatment.
• Usually linked to allergies, structural problems, or recurring infections.

Typical signs include constant nasal blockage, reduced sense of smell, and fatigue.

Common Symptoms of Sinusitis

Typical sinusitis symptoms may include:

• Facial pressure or headache that worsens when bending forward.
• Pain around the eyes, cheeks, or forehead.
• Nasal congestion or obstruction.
• Yellow or green nasal discharge.
• Bad breath.
• Fatigue and mild fever.
• Loss or reduction of smell or taste.

The Saudi Food and Drug Authority (SFDA) notes that using approved nasal sprays and decongestants can help relieve symptoms quickly when prescribed by a licensed physician.

Causes of Sinusitis

The main causes of sinusitis include:

• Viral or bacterial infections.
• Allergic rhinitis (seasonal or environmental allergies).
• Nasal polyps or deviated septum.
• Air pollution or smoking.
• Sudden weather or pressure changes.

In rare cases, fungal infections can cause sinusitis—especially in people with weakened immune systems or chronic illnesses like diabetes or asthma.

Sinusitis Treatment

1. Medical Treatment

• Antibiotics or sinus infection pills for bacterial cases.
• Nasal corticosteroid sprays to reduce inflammation.
• Decongestants and pain relievers.
• In chronic or severe cases, Functional Endoscopic Sinus Surgery (FESS) may be recommended to open the sinus passages.

All medications must be prescribed by a doctor and approved by the Saudi Food and Drug Authority to ensure safety and effectiveness.

2. Home and Natural Remedies

• Steam inhalation several times a day.
• Warm compresses on the face to relieve pressure.
• Adequate hydration and rest.
• Using saline nasal rinses.
• Treating sinusitis with olive oil: while olive oil may help moisturize nasal tissues, it should only be used as a supportive remedy—not a replacement for medical care.

Can Sinusitis Cause Tooth Pain?

Yes. The maxillary sinuses are located just above the upper teeth. When inflamed, they can cause referred pain that feels like a toothache.
A proper clinical assessment by an ENT or dentist helps distinguish whether the pain originates from the sinuses or the teeth.

Sinusitis in Children

Sinusitis in children often follows a prolonged cold or viral infection.
Common signs include:

• Persistent runny nose.
• Chronic night-time cough.
• Facial pressure or irritability.
• Difficulty breathing during sleep.

If symptoms last for more than 10 days or worsen, consult a paediatric ENT specialist promptly.

When to See a Doctor

You should visit an ENT specialist if you experience:

• Symptoms lasting longer than 10 days.
• Facial pain or swelling around the eyes.
• Fever above 38.5°C.
• Frequent or recurrent sinus infections.

FAQ

Does sinusitis cause high blood pressure?

Not directly. However, pain, congestion, and stress from chronic sinusitis may cause temporary increases in blood pressure.

How do I know if I have sinusitis?

If you have facial pain, nasal congestion, thick discharge, and headaches lasting more than a week, you likely have sinusitis and should see a doctor for confirmation.

What are the symptoms of sinusitis affecting the eyes?

Patients may experience pain around or behind the eyes, mild eyelid swelling, or blurry vision in advanced cases.

Conclusion

Sinusitis is a common yet often underestimated condition that can affect your breathing, sleep, and overall well-being.
The good news is that with timely diagnosis and proper treatment — whether medical or surgical — most patients recover fully and regain their quality of life.

If you’re experiencing sinusitis symptoms such as persistent nasal congestion, headaches, or facial pressure, don’t ignore them. Early medical evaluation by an ENT specialist can prevent complications and ensure lasting relief.
