Sinusitis

Your sinuses are air-filled cavities located within the bones of your face - behind your cheekbones, in your forehead, and around the bridge of your nose. Under normal conditions, they produce a thin mucus that drains quietly through narrow channels into the nasal cavity. Sinusitis occurs when those channels become blocked, and the sinuses become inflamed, usually due to an infection. The mucus that should drain freely gets trapped, and that is when the discomfort begins.

The most common types of sinusitis are acute and chronic sinusitis. Most people who develop sinusitis have the acute form. This typically follows a cold or flu, lasts one to three weeks, and resolves with appropriate management. The body’s immune system clears the underlying infection, the channels open up, and normal drainage resumes.

Chronic sinusitis is a different matter entirely. By definition, it persists beyond twelve weeks. Patients with chronic sinusitis often have underlying factors - structural issues in the nasal passages, persistent allergy, or a suppressed immune system- that prevent full resolution. Chronic sinusitis is less common, but it does require a more thorough evaluation to understand what is sustaining it.

The most common trigger we see is a straightforward upper respiratory infection - the viruses responsible for the common cold and flu can spread to the sinuses and cause secondary inflammation. In most of these cases, the infection stays viral and clears on its own, though it may take longer than patients expect.

Dental infections are worth mentioning specifically because they are an underappreciated cause.

Other contributing factors include:

• Allergic rhinitis — nasal allergies cause chronic swelling of the nasal lining, which narrows the drainage channels and makes sinusitis more likely
• Structural abnormalities such as a deviated nasal septum or nasal polyps that impede drainage
• A weakened immune system — patients living with HIV, those on chemotherapy, or anyone with a chronic illness affecting immunity are more susceptible
• Asthma, which frequently co-exists with sinusitis and shares similar inflammatory pathways
• Pregnancy, which increases nasal congestion due to hormonal changes
• Smoking, which damages the mucosal lining and impairs the normal clearance mechanisms of the sinuses

The most common feature of sinusitis is facial pain or pressure - a deep, throbbing discomfort felt over the cheeks, the forehead, or around the eyes, depending on which sinuses are involved. This pain tends to worsen when you bend your head forward or make sudden movements. Chewing can aggravate it, particularly when the cheekbone sinuses are affected.

A blocked nose is almost universal - the congestion can feel complete, as though both nostrils are shut, and patients often notice a temporary loss of smell.

Other symptoms that patients report include:

• A persistent headache, often described as a dull, heavy pressure rather than a sharp pain
• Bad breath, caused by the infected mucus draining at the back of the throat
• Toothache in the upper jaw - even when the teeth themselves are healthy
• A cough that worsens at night as mucus drains backwards while lying down
• A feeling of fullness or pressure in the ears
• Pronounced fatigue

For most cases of acute viral sinusitis, the approach is supportive - the goal is to manage symptoms while the immune system does its work. This includes adequate rest, staying well hydrated, and using paracetamol or ibuprofen to control pain and bring down fever. Warm facial compresses over the affected sinus can offer genuine relief. Saline nasal rinses, which you can prepare simply with salt and clean water, help to clear congestion and keep the passages moist.

Decongestant nasal sprays are useful for short-term relief of a blocked nose, though they should not be used for more than a few days at a time to avoid rebound congestion. If symptoms are severe, worsening after an initial improvement, or lasting beyond ten days without signs of recovery, a bacterial infection may have developed, and antibiotics may be appropriate at that point.

When sinusitis is recurrent or chronic, investigation becomes important. We may request imaging to assess the sinuses in detail, examine the nasal passages directly, or evaluate for underlying allergy. In some cases, particularly where there is a structural obstruction or persistent polyps, surgical intervention to open the drainage pathways provides lasting relief where medication alone has not been sufficient.
