Healthy sinuses are naturally filled with air. But when they become blocked and trap fluid, they create the perfect environment for bacteria, viruses, or fungi to grow, often leading to a sinus infection. Several factors can contribute to sinus blockage, including the common cold, allergic rhinitis (inflammation of the nasal lining due to allergens), nasal polyps, and a deviated septum. Knowing how to spot the symptoms early and treat sinusitis effectively is key to avoiding prolonged discomfort.
What Are Sinuses?
Your sinuses are air-filled cavities located within your skull. There are four pairs (eight in total) of sinuses positioned in specific areas:
- Above the eyes
- Between the eyes
- Behind the nose
- Below the eyes, behind the cheeks
Types of Sinusitis
Sinusitis is classified into three main types based on symptom duration:
Acute Sinusitis: Symptoms last for up to four weeks and are usually caused by bacterial infections.
Chronic Sinusitis: Symptoms persist for more than three months and can result from bacterial or fungal infections.
Subacute Sinusitis: Lasting between one to three months, this form bridges the gap between acute and chronic sinusitis.

Acute Sinusitis: Symptoms and Causes
Acute sinusitis often follows the common cold, a viral infection that usually resolves within 10 days but can linger up to four weeks. Symptoms include:
- Nasal congestion and difficulty breathing
- Thick green or yellow mucus
- Postnasal drip (mucus draining down the back of the throat)
- Pressure, swelling, and discomfort around the nasal passages
- Headaches, ear pressure, and coughing
Chronic Sinusitis: Longer-Lasting Symptoms
Chronic sinusitis mirrors the symptoms of acute sinusitis but lasts much longer, typically beyond three months. Common causes include:
- Nasal polyps
- A deviated septum
- Allergies
- Recurrent respiratory infections
- Conditions like cystic fibrosis or HIV that compromise the immune system
Subacute Sinusitis: A Middle Ground
Subacute sinusitis is a less intense form of sinusitis, with symptoms lasting between four and twelve weeks. Environmental irritants like dust, pollen, and smoke can trigger this type of sinus infection.

Additionally, allergic sinusitis may cause an itchy sensation in the nose, eyes, and throat, with symptoms fluctuating depending on the season and allergen exposure.
Sinus Headache: A Common Symptom
Sinusitis can also cause headaches, resulting in constant dull pain behind the eyes, in the cheekbones, forehead, or around the nose. The pain intensifies when you move your head suddenly or bend forward, and temperature changes can exacerbate the discomfort.
Duration of Sinusitis
To be diagnosed with chronic sinusitis, symptoms must last for at least 12 weeks. Some people may experience symptoms for much longer, sometimes over a decade, though there may be periods of improvement. Acute sinusitis, on the other hand, typically resolves within four weeks.
Is Sinusitis Contagious?
Sinusitis itself is not contagious, but its underlying causes often are. Most sinusitis cases are linked to viral infections, like the common cold, which spreads through respiratory droplets. Bacterial infections such as Streptococcus pneumoniae, which can cause pneumonia and meningitis, can also lead to sinusitis and may spread through close contact.

Sinusitis Treatment Options
Treating sinusitis involves several approaches, depending on the cause and severity:
Antibiotics: Prescribed for bacterial infections. Acute sinusitis may require 10-14 days of antibiotics, while chronic sinusitis may need longer treatment.
Pain Relievers: Over-the-counter options like ibuprofen or acetaminophen can help alleviate discomfort.
Bioelectronic Sinus Device: A microcurrent device available over the counter can reduce sinus inflammation, pain, and congestion.
Decongestants: These reduce mucus production and are available as nasal sprays or oral tablets. Use nasal sprays cautiously to avoid increased congestion from prolonged use.
Allergy Medications: If allergies are a contributing factor, antihistamines, allergy shots, or avoiding allergens can help.
Steroids: Inhaled or oral steroids can reduce sinus membrane swelling in chronic cases.
Nasal Irrigation: Saline solutions can help clear out mucus, but they should be used cautiously, particularly in cases of ear infections or after surgery.
Can Sinusitis Be Prevented?
While it’s impossible to completely prevent sinusitis, you can reduce your risk by:
- Avoiding smoking and secondhand smoke
- Practicing good hygiene, especially during cold and flu season
- Steering clear of known allergens
- Discussing potential surgical options with your doctor if sinus problems persist
