A blocked nose is extremely common, especially during a cold or allergy flare. But if your nose remains congested for weeks, repeatedly becomes blocked, or feels obstructed even when you do not have a cold, there may be an underlying reason that needs to be identified.
If you frequently ask “Why is my nose always blocked?”, “What causes nose block?” or “Why do I have a constant blocked nose but no cold?”, several conditions may need to be considered. Nasal obstruction can result from allergies, non-allergic rhinitis, chronic sinus inflammation, enlarged turbinates, nasal polyps, a deviated nasal septum, narrowing of the nasal valve or a combination of inflammatory and structural problems.
In India, environmental exposure may also influence symptoms. Dust, traffic pollution, tobacco smoke, construction particles, strong fragrances and workplace irritants can aggravate an already sensitive nasal lining. Indoor allergens such as dust mites and mould may also contribute to year-round nasal congestion.
This updated 2026 guide explains the common causes of persistent nasal blockage, how an ENT specialist evaluates the problem, treatment options, warning signs and when procedures such as septoplasty, sinus surgery or functional nasal surgery may be considered.
Persistent obstruction can be assessed to determine whether the main cause is allergic, inflammatory, sinus-related or structural.
Assessment and treatment may differ for nasal blockage, sinusitis, deviated septum, nasal polyps and other breathing problems.
What Does a Blocked Nose Actually Mean?
A blocked nose, medically described as nasal congestion or nasal obstruction, occurs when airflow through one or both nasal passages becomes restricted.
The sensation does not necessarily mean that the nose is filled with mucus. In many people, congestion occurs because tissues lining the nasal passages become swollen. In others, a structural narrowing physically reduces the space through which air can travel.
The nose contains turbinates, mucosal tissue, cartilage, bone and narrow valve areas that collectively regulate airflow. A problem affecting any of these structures can make nasal breathing feel restricted.
Persistent difficulty breathing through the nose may therefore require specific nasal blockage treatment based on the underlying cause rather than repeated temporary relief of the symptom. If you are experiencing ongoing difficulty breathing through the nose , an ENT assessment can help determine whether the problem is inflammatory, structural or related to another nasal condition.
What Causes Nose Block?
What causes nose block? In most cases, the explanation falls into one of three broad categories: inflammation, structural narrowing, or a combination of both. Temporary inflammation from a viral infection can cause congestion for several days, while allergic rhinitis, non-allergic rhinitis and chronic rhinosinusitis can keep the lining of the nose swollen for much longer. Allergic rhinitis may be triggered by pollen, dust mites, mould, animal allergens and other substances. Non-allergic rhinitis can produce similar congestion without a conventional allergy and may be aggravated by smoke, pollution, strong fragrances, temperature changes or chemical irritants.
Structural obstruction becomes particularly important when symptoms are persistent or when one side consistently feels narrower. A deviated nasal septum can reduce the width of one nasal passage, enlarged turbinates can occupy additional airway space, nasal polyps may physically obstruct airflow, and narrowing or weakness of the nasal valve can make breathing more difficult. Some people have more than one problem at the same time, such as allergic rhinitis together with a deviated septum.
Constant Blocked Nose but No Cold: What Could Be Causing It?
A constant blocked nose but no cold often suggests that something other than a temporary viral infection is contributing to the obstruction. Persistent allergic rhinitis is one possibility. It can keep the lining of the nose swollen even when you do not have fever, body aches or other symptoms normally associated with a cold. Year-round triggers may include dust mites, indoor mould, animal allergens or workplace exposure. Non-allergic rhinitis can also cause continuing congestion without a cold and without a conventional allergic reaction.
If the nose feels blocked almost every day, particularly when one nostril remains consistently worse, structural causes become more important to consider. A deviated septum, enlarged inferior turbinates, nasal polyps, nasal valve narrowing or changes following an old nasal injury may reduce airflow even when there is no infection. Because these conditions can produce similar symptoms, an ENT examination and, where appropriate, nasal endoscopy can help identify where the obstruction is occurring.
Persistent one-sided blockage deserves particular attention if it occurs with repeated bleeding, unusual discharge, facial swelling or progressively worsening symptoms. If symptoms are continuing, an ENT surgeon in Rajkot can assess whether the problem is predominantly inflammatory, structural or a combination of both.
Persistent Nasal Blockage in India: Why Local Exposure Matters
The medical causes of nasal obstruction are similar worldwide, but the environment can influence how often symptoms occur and how severe they become.
In Indian cities, regular exposure to traffic exhaust, construction dust, road dust, tobacco smoke, incense, strong fragrances and workplace irritants can aggravate a sensitive nasal lining. These exposures do not necessarily create structural obstruction, but they may worsen rhinitis and nasal inflammation in susceptible people.
Seasonal patterns also matter. Some people notice worsening symptoms during dry and dusty periods, increased pollen exposure or humid weather that may favour indoor allergens such as mould.
Environmental exposure should therefore form part of the clinical history, but persistent congestion should not automatically be attributed to pollution. Structural causes involving the septum, turbinates or nasal valve may still need to be considered.
Common Causes of a Persistently Blocked Nose
1. Allergic Rhinitis
Allergic rhinitis occurs when the immune system reacts to an allergen and causes inflammation within the nasal lining. Symptoms may include nasal blockage, repeated sneezing, clear watery discharge, nasal itching and itchy or watery eyes.
Symptoms may be seasonal or may occur throughout the year depending on what is triggering the reaction.
2. Non-Allergic Rhinitis
Not every case of rhinitis is caused by allergy. In non-allergic rhinitis, the nasal lining can react to irritants or environmental changes such as smoke, pollution, perfume, cleaning chemicals or changes in temperature.
3. Deviated Nasal Septum
The nasal septum is the wall of cartilage and bone separating the right and left nasal passages. If it is substantially displaced to one side, one nasal airway can become narrower.
A deviated septum may be developmental or may follow an injury to the nose. Symptoms can include persistent one-sided obstruction, difficulty breathing through the nose and greater congestion during a cold or allergy flare.
Where septal deviation is significantly affecting airflow, treatment for a deviated septum depends on the degree of obstruction, associated inflammation and the effect on everyday breathing.
4. Enlarged Turbinates
Turbinates are normal structures positioned along the side walls of the nasal cavity. They warm, humidify and filter inhaled air.
When they remain enlarged because of allergy or chronic inflammation, they may occupy too much airway space and contribute to ongoing congestion.
5. Chronic Rhinosinusitis
Chronic rhinosinusitis involves prolonged inflammation of the nasal and sinus lining. It is different from simply having congestion for a few days during a cold.
Symptoms may include persistent obstruction, nasal discharge, postnasal drainage, reduced sense of smell and facial pressure. When chronic sinus inflammation is contributing to symptoms, sinusitis treatment is directed at the underlying inflammatory or sinus condition rather than nasal blockage alone.
If sinus infections keep returning, it may also be useful to understand the available approaches to recurring sinus infections treatment and discuss the pattern of symptoms with an ENT specialist.
When chronic or recurrent sinus symptoms require specialist assessment, a sinus specialist can help evaluate whether the symptoms are related to persistent sinus inflammation, recurrent infection, nasal obstruction or another underlying problem.
6. Nasal Polyps
Nasal polyps are soft, non-cancerous inflammatory growths that develop within the nose or sinuses.
Small polyps may cause few symptoms, but larger or multiple polyps can interfere with airflow and reduce the sense of smell. Persistent cases may require specialist nasal polyp treatment based on their size, symptoms and associated sinus inflammation.
For patients specifically looking for nasal polyp treatment in Rajkot , an ENT evaluation can help determine the extent of the polyps and whether medical or procedural treatment is appropriate.
7. Nasal Valve Narrowing or Collapse
The nasal valve is one of the narrowest areas of the nasal airway. If this area is naturally narrow, weakened or altered following injury or previous surgery, airflow can become restricted.
Nasal valve problems may become particularly noticeable when exercising or taking a deep breath. In selected patients where external nasal structure also contributes to obstruction, functional rhinoplasty may be considered as part of treatment.
8. Viral Respiratory Infection
A common cold can temporarily inflame the nasal lining and increase mucus production. Unlike many structural causes, the blockage usually improves as the infection resolves.
9. Environmental Irritants
Dust, smoke, pollution, chemical fumes and strong fragrances can irritate the nasal lining and worsen congestion, particularly in people whose nasal passages are already sensitive or inflamed.
10. Overuse of Decongestant Nasal Sprays
Some fast-acting topical decongestant sprays are intended for short-term use. Using them for longer than recommended can lead to rebound congestion, sometimes called rhinitis medicamentosa.
This can create a cycle in which the nose becomes blocked again when the spray wears off, encouraging increasingly frequent use.
Blocked Nose Causes: Quick Comparison
| Possible Cause | Typical Pattern | Other Possible Clues |
|---|---|---|
| Allergic rhinitis | Intermittent or persistent | Sneezing, itching, watery discharge, eye symptoms |
| Non-allergic rhinitis | Recurring congestion | May be triggered by smoke, pollution or strong smells |
| Deviated septum | Often persistent; one side may be worse | Long-standing breathing difficulty |
| Enlarged turbinates | Persistent or fluctuating | May worsen with allergy or inflammation |
| Chronic rhinosinusitis | Long-lasting | Discharge, reduced smell, facial pressure |
| Nasal polyps | Persistent | Reduced smell and chronic congestion |
| Nasal valve narrowing | Persistent | May be more noticeable with exercise or deep breathing |
| Common cold | Temporary | Runny nose, sore throat and other viral symptoms |
Why Is One Side of My Nose Always Blocked?
Airflow through the two sides of the nose is not always equal. A normal physiological process called the nasal cycle causes the degree of congestion on each side to alternate periodically.
However, if the same side remains consistently obstructed, possible causes include a deviated septum, enlarged turbinate, nasal valve narrowing, previous injury, a nasal polyp or another localised condition.
If one nostril remains persistently more blocked than the other, read our detailed guide on one-sided nasal blockage to understand common causes, warning signs and when an ENT assessment may be appropriate.
Previous trauma can sometimes affect both the internal septum and the external alignment of the nose. Where the nose is visibly crooked as well as difficult to breathe through, correction of a crooked nose may require assessment of both appearance and nasal function.
Why Is My Nose Blocked Even When There Is No Mucus?
Nasal congestion does not require mucus to be present.
Swelling of the nasal lining can narrow the airway even when the nose feels dry. Structural conditions such as a deviated septum, enlarged turbinates or nasal valve narrowing can also make the nose feel obstructed without producing significant discharge.
This is why repeatedly trying to clear mucus may not help when the actual problem is tissue swelling or physical narrowing of the nasal airway.
Can a Constantly Blocked Nose Affect Sleep?
Yes. Persistent nasal obstruction can make comfortable nasal breathing more difficult when lying down and may encourage mouth breathing.
Some people also experience snoring, dry mouth on waking, restless sleep or a feeling that their nose becomes particularly blocked at night.
Nasal obstruction is not the same as obstructive sleep apnoea. Persistent snoring, witnessed pauses in breathing, choking during sleep or excessive daytime sleepiness should be medically assessed.
Why Does My Nose Feel More Blocked During Exercise?
Exercise increases airflow demand. A nasal airway that feels adequate while resting may become noticeably restrictive when breathing requirements increase.
Structural narrowing involving the septum or nasal valve can therefore become more apparent during physical activity.
How Is a Constantly Blocked Nose Diagnosed in 2026?
Evaluation begins by understanding the pattern of symptoms rather than automatically ordering a scan.
An ENT specialist may ask how long the blockage has been present, whether one or both sides are affected, whether symptoms alternate, whether you experience sneezing or itching, changes in smell, facial pressure, previous injury, allergy symptoms, environmental triggers and what nasal medicines you have already tried.
Choosing the right specialist is also important when symptoms are persistent. Factors such as experience with nasal and sinus conditions, structural nasal problems and appropriate diagnostic evaluation are discussed in more detail when considering how to choose an ENT specialist in Rajkot .
Physical Nasal Examination
Examination can help identify visible septal deviation, swelling of the nasal lining, enlarged turbinates, discharge and other abnormalities.
Nasal Endoscopy
When clinically indicated, a thin endoscope allows the ENT specialist to inspect areas deeper inside the nasal cavity that cannot be fully assessed during a routine examination.
Endoscopy may help evaluate nasal polyps, inflammation, drainage pathways, septal abnormalities and other possible causes of persistent obstruction.
Do You Always Need a CT Scan?
No. A CT scan is not automatically required for every person with nasal congestion.
Imaging may be appropriate in selected patients when sinus disease, complications, surgical planning or another condition requires additional assessment. The decision should be based on symptoms and clinical findings.
Allergy-Related Blockage vs Structural Nasal Blockage
| Feature | Allergy / Inflammation | Structural Obstruction |
|---|---|---|
| Pattern | Can fluctuate with exposure | May remain consistently present |
| Sneezing | Common with allergy | Usually not a defining symptom |
| Itching | Common with allergy | Usually absent |
| One side consistently worse | Possible, but less characteristic | Can occur with septal deviation or valve narrowing |
| Response to medication | May improve substantially | Medication cannot physically correct structural narrowing |
How Is a Persistently Blocked Nose Treated?
Treatment should target the diagnosed cause rather than simply trying to temporarily open the nose.
Saline Nasal Irrigation
Saline irrigation may help remove mucus, allergens and irritants from the nasal passages. Safe preparation and an appropriate water source are important.
Allergy Management
If allergy is contributing to symptoms, treatment may involve reducing exposure to identified triggers and using appropriate medicines recommended by a healthcare professional.
Intranasal Corticosteroid Sprays
Nasal corticosteroid sprays are commonly used for inflammatory nasal conditions such as allergic rhinitis and may also be part of treatment for some patients with chronic rhinosinusitis or nasal polyps.
They work differently from fast-acting topical decongestants and should be used with appropriate technique and medical guidance.
Antihistamines
Antihistamines may help when allergy contributes to symptoms, particularly sneezing, itching and watery discharge.
Decongestants
Decongestants can provide temporary relief in selected situations, but they are not appropriate for everyone and should not replace assessment of long-lasting symptoms.
When Can Surgery Be Considered?
Surgery is not required for most temporary nasal congestion and should not be assumed to be necessary simply because the nose feels blocked.
Surgery may be considered when a significant structural abnormality has been identified, symptoms meaningfully affect breathing or quality of life, appropriate non-surgical treatment has not adequately controlled the symptoms, and the proposed procedure addresses the identified cause.
Septoplasty for Persistent Nasal Blockage
Septoplasty is surgery used to straighten a significantly deviated nasal septum.
Medication can reduce associated nasal inflammation, but it cannot physically straighten a deviated septum. When septal deviation is an important cause of long-term obstruction, septoplasty surgery may therefore be considered after appropriate assessment.
Septoplasty is often confused with rhinoplasty, but their primary purposes are different. Understanding rhinoplasty vs septoplasty can help clarify whether the concern involves mainly the internal septum, the external nasal framework or both.
Treatment for Enlarged Turbinates
When turbinate enlargement is mainly related to inflammation, appropriate medical treatment may reduce the swelling.
If the turbinates continue to cause significant obstruction despite appropriate treatment, a turbinate procedure may be considered depending on the individual findings.
When Can Sinus Surgery Be Considered?
Nasal blockage caused by chronic sinus disease is managed differently from isolated septal deviation. Medical treatment is commonly used first, while selected patients with persistent sinus disease may eventually require surgical management.
In appropriate cases, Functional Endoscopic Sinus Surgery (FESS) may be considered to treat specific sinus conditions identified during evaluation.
If sinus symptoms continue to recur despite appropriate management, a recurring sinus infections treatment assessment may help identify factors contributing to repeated episodes.
Can Rhinoplasty Help Nasal Breathing?
Rhinoplasty is commonly associated with changing the appearance of the nose, but structural nasal surgery can also have a functional purpose.
If obstruction involves the external nasal framework or nasal valve, functional rhinoplasty may be considered in selected patients.
This is different from surgery performed primarily for appearance. Understanding the distinction between cosmetic and functional rhinoplasty can be particularly useful when both breathing and nasal shape are concerns.
When nasal shape is also a concern, the lower part of the nose may need separate assessment. Problems involving tip width, projection, drooping or asymmetry are evaluated differently from internal causes of nasal blockage. You can read more about nose tip correction in Rajkot and how tip shape and support are assessed during rhinoplasty planning.
What If Both the Septum and External Nose Affect Breathing?
Some people have obstruction involving more than one part of the nasal airway. For example, significant septal deviation may exist together with narrowing involving the external nasal framework or nasal valve.
In selected cases, septorhinoplasty can address both internal and external structural components within an individualised surgical plan.
When Should You See an ENT Doctor for a Blocked Nose?
Consider an ENT assessment if:
- Your nose remains blocked for several weeks
- The problem repeatedly returns
- One side remains consistently more blocked
- Nasal breathing affects sleep or exercise
- Your sense of smell has reduced
- You repeatedly experience sinus-type symptoms
- You have a history of nasal injury
- Appropriate allergy treatment has not controlled symptoms
- You repeatedly rely on topical decongestant sprays
If you are based in Rajkot or nearby, an ENT specialist in Rajkot can evaluate nasal, sinus and related breathing concerns and determine whether further investigation is appropriate.
If your symptoms also include a blocked or muffled ear, ear fullness or recurrent wax buildup, read our guide on ear wax removal in Rajkot to understand when wax may be responsible and when professional ear examination may be appropriate.
ENT concerns can also involve oral function. If you or your child has restricted tongue movement, feeding difficulty, speech-related concerns or other symptoms that may be associated with tongue-tie, read our guide on tongue-tie release in Rajkot to understand symptoms, assessment, treatment options, the procedure and recovery.
Warning Signs That Should Not Be Ignored
Most nasal congestion is caused by non-emergency conditions, but unusual or progressive symptoms need medical attention.
- Persistent one-sided nasal obstruction
- Repeated or unexplained nosebleeds
- Persistent bloody nasal discharge
- Significant facial swelling
- Severe or rapidly increasing facial pain
- High fever with significant illness
- Sudden major worsening of breathing
- Symptoms following significant facial trauma
- Visual symptoms associated with severe facial or sinus symptoms
What Can You Do at Home for Nasal Congestion?
Simple measures may help when the cause is suitable for home management.
- Maintain adequate hydration
- Use an appropriate saline nasal spray or rinse
- Avoid cigarette and tobacco smoke
- Reduce exposure to known allergens where practical
- Limit exposure to strong fumes and fragrances
- Use prescribed nasal medicines correctly
- Maintain reasonable indoor air quality
Is a Blocked Nose the Same as Sinusitis?
No. A blocked nose is a symptom. Sinusitis or rhinosinusitis refers to inflammation affecting the nose and sinus cavities.
Sinus disease can cause congestion, but so can allergic rhinitis, non-allergic rhinitis, septal deviation, enlarged turbinates, nasal polyps and nasal valve problems.
This distinction matters because treatment for sinusitis can be very different from treatment for structural nasal obstruction.
If symptoms involve repeated or persistent sinus problems, consulting a sinus specialist may help determine whether chronic inflammation, recurrent infection or another underlying issue is contributing to the symptoms.
Cost of Treatment for a Blocked Nose in Rajkot, India
There is no single meaningful price for blocked nose treatment because the cost depends on what is causing the obstruction.
Treatment may involve only consultation and medicines, or it may require nasal endoscopy, allergy evaluation, imaging, septoplasty, sinus surgery, turbinate treatment or functional nasal surgery.
Surgical costs in India can also vary according to the procedure, complexity, hospital, anaesthesia, investigations, room category and postoperative care.
Where rhinoplasty or septorhinoplasty is being considered, the cost of rhinoplasty surgery depends on different factors and should not be used as an estimate for unrelated ENT treatment.
Can Health Insurance Cover Nasal Surgery in India?
Insurance coverage depends on the individual policy, medical indication, insurer requirements and documentation.
Surgery undertaken for a documented functional problem may be considered differently from surgery performed primarily for cosmetic reasons.
Patients should confirm eligibility, waiting periods, exclusions, pre-authorisation requirements and documentation directly with their insurer or third-party administrator.
What Happens During an ENT Consultation for Nasal Blockage?
Step 1: Discuss the Pattern of Symptoms
Your doctor will establish whether the obstruction is temporary, intermittent or persistent and whether one or both sides are affected.
Step 2: Review Relevant Medical History
Allergy history, previous nasal injuries, previous surgery, medicines and environmental triggers may all be relevant.
Step 3: Examine the Nose
The internal and external nose may be assessed for septal deviation, mucosal swelling, turbinate enlargement and other abnormalities.
Step 4: Nasal Endoscopy When Appropriate
Endoscopy may be used when deeper assessment of the nasal passages is clinically required.
Step 5: Further Investigations When Indicated
Imaging, allergy assessment or other investigations may be recommended depending on the symptoms and examination findings.
Step 6: Individual Treatment Plan
Treatment is then selected according to the diagnosed cause rather than applying the same approach to every patient with nasal congestion.
What Should You Ask If Nasal Surgery Is Recommended?
If surgery is recommended, it is important to understand what anatomical problem the operation is intended to correct, whether the objective is functional, cosmetic or both, what alternatives are available and what recovery is likely to involve.
Questions about surgical goals, expected results, risks and recovery are particularly important before rhinoplasty or septorhinoplasty. These are among the key questions to ask a rhinoplasty surgeon before making a treatment decision.
What Is Recovery Like After Structural Nasal Surgery?
Recovery varies depending on whether someone undergoes septoplasty, sinus surgery, turbinate treatment, functional rhinoplasty or septorhinoplasty.
Temporary swelling and congestion can occur after nasal surgery, which means breathing may not feel completely normal immediately after the procedure.
Recovery following rhinoplasty or septorhinoplasty usually develops in stages rather than all at once. The week-by-week rhinoplasty recovery timeline explains early healing and the gradual return towards normal activity in more detail.

Consult an ENT Surgeon in RajkotFrequently Asked Questions About a Constantly Blocked Nose
What causes nose block?
Nose block can result from swelling of the nasal lining, allergies, non-allergic rhinitis, viral infection, chronic rhinosinusitis, a deviated septum, enlarged turbinates, nasal polyps, nasal valve narrowing or prolonged use of certain decongestant sprays.
Why do I have a constant blocked nose but no cold?
Persistent blockage without typical cold symptoms may occur with allergic or non-allergic rhinitis, chronic nasal inflammation, a deviated septum, enlarged turbinates, nasal polyps or nasal valve narrowing.
Why is my nose always blocked?
A persistently blocked nose may be inflammatory, allergic or structural. Some people have more than one contributing problem, such as allergy together with a deviated septum.
Why is only one nostril blocked?
Airflow naturally alternates to some extent because of the nasal cycle. Persistent blockage of the same side, however, may occur with septal deviation, turbinate enlargement, nasal valve narrowing or another localised condition.
Why is my nose blocked when there is no mucus?
The nasal tissues themselves may be swollen, or the airway may be structurally narrow. Nasal obstruction therefore does not require excess mucus to be present.
Can air pollution cause a blocked nose?
Dust, smoke, traffic exhaust and other irritants can aggravate the nasal lining and contribute to congestion in susceptible people. Persistent symptoms should still be assessed for other possible causes.
Can allergies cause nasal blockage without a runny nose?
Yes. Although sneezing and watery discharge are common with allergic rhinitis, some people experience congestion as the dominant symptom.
Can a deviated septum cause constant blockage?
Yes. A significantly deviated septum can narrow a nasal passage and cause persistent airflow restriction, often with one side feeling worse than the other.
Can enlarged turbinates block the nose?
Yes. Enlarged turbinates can occupy nasal airway space and contribute to persistent obstruction, particularly when allergy or chronic inflammation is also present.
Can nasal polyps cause constant congestion?
Yes. Larger or multiple nasal polyps may interfere with airflow and can also be associated with reduced sense of smell. If nasal polyps are suspected, an ENT evaluation can determine whether nasal polyp treatment in Rajkot is appropriate.
Do I need a CT scan for a blocked nose?
Not necessarily. Many causes can initially be evaluated through medical history, examination and sometimes nasal endoscopy. CT imaging is used when the clinical situation requires it.
Can a blocked nose be treated without surgery?
Yes. Many inflammatory and allergic causes can be treated medically. Surgery is generally considered when a significant structural problem has been identified or another surgical condition requires treatment.
Will nasal sprays fix a deviated septum?
Nasal medicines may reduce inflammation around a deviated septum, but they cannot physically straighten the septum itself.
Can septoplasty improve nasal breathing?
Septoplasty may improve airflow when clinically significant septal deviation is an important cause of nasal obstruction.
When should I see an ENT doctor?
Consider assessment when nasal blockage lasts for several weeks, keeps returning, consistently affects one side, interferes with sleep or breathing, reduces smell or occurs with bleeding or other concerning symptoms.
Conclusion
If you are searching for what causes nose block, the answer is not limited to a cold or sinus infection. Nasal obstruction can result from allergy, non-allergic inflammation, enlarged turbinates, chronic rhinosinusitis, nasal polyps, septal deviation, nasal valve narrowing, environmental irritants or medication-related rebound congestion.
A constant blocked nose but no cold particularly raises the possibility of persistent rhinitis or structural nasal obstruction. Identifying the actual cause is therefore more useful than repeatedly treating the sensation of congestion.
For people in Rajkot and elsewhere in India, pollution, dust and allergy exposure may aggravate symptoms, but persistent, one-sided or treatment-resistant blockage should also be evaluated for structural causes.
An ENT consultation in Rajkot can help differentiate between inflammatory and structural causes and determine whether treatment should involve allergy management, nasal medication, saline care, septoplasty, sinus treatment or another appropriately selected approach.
Find the Cause of Persistent Nasal Blockage
If your nose remains blocked despite not having a cold, appropriate ENT assessment can help determine whether allergy, inflammation, sinus disease or a structural nasal problem is responsible.
