When a blocked nose, facial pressure and thick mucus seem to go on for months, it is reasonable to ask: can chronic sinusitis be treated? For many people, symptoms can be improved and brought under better control. The right approach depends on what is driving them, which is why persistent symptoms deserve more than repeated short-term cold remedies.
Chronic sinusitis is often called chronic rhinosinusitis because it involves both the nose and the sinuses. It is usually defined as symptoms lasting 12 weeks or more, alongside signs of ongoing inflammation seen during a clinical assessment. It can be frustrating, but it is not something you need to simply put up with.
Can chronic sinusitis be treated or managed?
Chronic sinusitis can often be managed with a combination of regular self-care, appropriate medicines and, for some people, specialist treatment. “Treated” does not always mean that symptoms disappear permanently after one course of treatment. Some people have an underlying tendency towards recurring symptoms, for example because of nasal polyps, allergies, asthma, structural narrowing inside the nose or sensitivity to irritants.
The practical aim is to reduce the day-to-day burden: less blockage and discharge, fewer flare-ups, improved sleep and a better sense of smell where possible. A doctor or qualified healthcare professional can help establish whether sinusitis is the likely explanation. Migraine, dental problems, allergy and other nasal conditions can also cause facial discomfort or congestion.
Symptoms that may suggest chronic rhinosinusitis
Common symptoms include nasal blockage or congestion, mucus from the nose or dripping into the throat, facial pressure, and a reduced or altered sense of smell. Symptoms may vary from day to day. Some people mainly notice a blocked nose and poor sleep, while others are troubled by post-nasal drip, cough or recurring pressure.
Facial pain or headache alone does not necessarily mean sinusitis. This is one reason an assessment can be useful when symptoms are persistent, recurrent or unclear.
Getting a clear diagnosis comes first
A healthcare professional will usually ask about the pattern and duration of symptoms, colds, allergies, asthma, smoking or vaping, medicines and previous treatments. They may examine the nose. If symptoms continue despite initial treatment, or nasal polyps or another cause are suspected, referral to an ear, nose and throat specialist may be considered.
Specialists may use a small camera to look inside the nose. In selected cases, a CT scan can show changes in the sinuses and help with treatment planning. Scans are not needed for everyone with congestion or facial pressure.
It is particularly useful to seek advice rather than self-treating repeatedly if symptoms have lasted longer than 12 weeks, keep returning, affect sleep or daily life, or are mostly on one side. A new loss of smell, troublesome asthma symptoms or suspected allergy may also change the treatment plan.
Everyday measures that may support symptom control
For chronic symptoms, consistency tends to matter more than looking for a one-off fix. Simple measures may make the nose feel more comfortable and can support a clinician-led treatment plan.
Saline nasal rinsing or irrigation may help clear mucus and crusting from the nasal passages. Use a product as directed, or water that has been appropriately prepared according to the device instructions. Keep the device clean and allow it to dry between uses. If rinsing causes significant pain, nosebleeds or ear discomfort, stop and ask a pharmacist, doctor or qualified healthcare professional for advice.
Avoiding cigarette smoke and other known irritants may also help. If allergy is suspected, discussing triggers and suitable treatment with a healthcare professional can be worthwhile. Staying hydrated and prioritising sleep can support general comfort, although they are not treatments for chronic sinusitis itself.
Steam is sometimes soothing for short periods, but evidence that it treats chronic sinusitis is limited. Take care around hot water to avoid burns, and do not put essential oils inside the nose.
Medicines a healthcare professional may consider
Treatment should match the person and the likely cause. A clinician may recommend a corticosteroid nasal spray or drops to reduce inflammation in the lining of the nose and sinuses. These treatments generally need regular use over time, rather than being judged after a day or two. Correct technique matters, so ask a pharmacist or clinician to demonstrate it if you are unsure.
For pain or discomfort, paracetamol may be suitable for some adults when used according to the label. It is not appropriate for everyone, particularly if you have certain health conditions or take other medicines that contain paracetamol. A pharmacist can help you check.
Antibiotics are not routinely useful for chronic sinusitis because the condition is not always caused by a bacterial infection. They may be considered in particular circumstances, such as a suspected bacterial flare-up, but this decision should be made by a prescriber based on your symptoms and assessment.
Decongestant nasal sprays can give short-term relief from nasal blockage for some people, but using them for too long can make congestion worse. Follow the product label and seek advice if you find you are relying on them repeatedly.
What about oral steroids and newer treatments?
Short courses of oral corticosteroids may sometimes be prescribed for severe symptoms, particularly in people with nasal polyps. Because these medicines can have significant side effects, they are not a routine long-term solution and require a careful discussion of benefits and risks.
For a small number of people with severe chronic rhinosinusitis with nasal polyps, specialist services may consider biologic medicines. These are prescription treatments used in specific circumstances and are usually considered after assessment of previous treatments, associated conditions and symptom severity.
When might sinus surgery be considered?
Surgery is not the first step for most people, but it may be an option when well-used medical treatment has not provided enough improvement, or when scans and specialist examination show a problem that surgery could address. The most common procedure is endoscopic sinus surgery, performed through the nostrils without external cuts.
The purpose is usually to improve ventilation and drainage pathways and to allow topical treatments to reach the sinus areas more effectively. It is not a guaranteed permanent cure. Ongoing saline rinsing and prescribed nasal treatment may still be needed afterwards, especially if inflammation, polyps or allergy continue to play a part.
A specialist should explain the likely benefits, the limits of surgery, recovery expectations and possible risks, including bleeding, infection and the need for further treatment.
When to seek urgent medical advice
Most sinus symptoms are not an emergency, but certain symptoms need prompt assessment. Seek urgent medical advice for swelling or redness around an eye, changes in vision, severe or rapidly worsening headache, confusion, a stiff neck, high fever, or severe pain that is not controlled with usual measures. These symptoms can have causes other than sinusitis and should not be managed at home.
Also arrange medical advice if symptoms are worsening, persist despite treatment, repeatedly return, or you have a weakened immune system. Children, pregnant people and anyone with a significant long-term condition may need individual guidance before using medicines or nasal products.
A realistic next step
If your symptoms have lasted 12 weeks or longer, keep a short record of what you notice: blockage, discharge, smell changes, pressure, sleep disruption, possible triggers and treatments already tried. This can make a consultation more productive and help identify whether chronic sinusitis, allergy or another condition needs attention.
There is no single approach that suits everybody, but there are meaningful options beyond simply waiting for symptoms to pass. The most useful next step is often a clear assessment and a plan you can follow consistently, with review if it is not helping.
