If nasal congestion, facial pressure, drainage, or a reduced sense of smell has been part of your daily life for months, you may be wondering whether you have chronic sinusitis or something else.
Chronic sinusitis, also called chronic rhinosinusitis, may be suspected when at least two key symptoms, such as nasal congestion, nasal drainage, facial pressure, or a reduced sense of smell, persist for 12 weeks or longer. Symptoms alone, however, cannot confirm the diagnosis. An ENT evaluation is needed to look for signs of ongoing inflammation and determine what is causing your symptoms.
Because chronic sinusitis can resemble allergies, recurrent infections, or other nasal conditions, the five questions below are designed to help you recognize a pattern, not diagnose yourself. If several sound familiar, an evaluation at Southern California ENT and Allergy Associates can help determine what is actually happening in your nose and sinuses.
Chronic Sinusitis Self-Test: 5 Questions to Ask Yourself
Answer each question based on how you have felt over the past several weeks, rather than how you feel on one particularly good or bad day.
Question 1: Have your symptoms lasted 12 weeks or longer?
Duration is one of the biggest clues separating chronic sinusitis from a short-lived respiratory illness. Acute sinus symptoms often improve within days or weeks, while chronic sinusitis is defined by symptoms that persist for at least 12 weeks.
Symptoms may fluctuate during that time. Having occasional better days does not necessarily mean the underlying problem has resolved.
Question 2: Do you regularly experience pressure or discomfort around your cheeks, eyes, or forehead?
Facial pressure or aching can occur with chronic sinus inflammation, although it is not specific to sinusitis. Other conditions can also cause facial pain or headaches.
Your doctor considers this symptom alongside congestion, drainage, changes in smell, and examination findings rather than using facial pressure alone to make a diagnosis.
Question 3: Does nasal congestion make it difficult to breathe comfortably through your nose?
Persistent nasal obstruction is another common symptom of chronic sinusitis. Swelling inside the nose, enlarged turbinates, nasal polyps, a deviated septum, or other conditions can narrow the space available for airflow.
Determining why your nose feels blocked is important because not every cause of chronic congestion requires the same treatment.
Question 4: Do you have persistent nasal drainage or post-nasal drip?
Chronic sinusitis can cause drainage from the nose or mucus that moves down the back of the throat. Some patients describe frequent throat clearing or the sensation that mucus is constantly present.
Drainage may be thick, clear, or discolored. Mucus color alone does not determine whether a bacterial infection is present.
Question 5: Has your sense of smell noticeably decreased?
A reduced sense of smell, called hyposmia, is another common symptom associated with chronic sinusitis. Ongoing inflammation, nasal polyps, or obstruction within the nasal passages can interfere with normal smell.
Changes in smell can have other causes as well, which is another reason persistent symptoms should be evaluated rather than self-diagnosed.
What Do Your Answers Mean?
This is not a scored diagnostic test, and there is no specific number of “yes” answers that confirms chronic sinusitis.
If several of these symptoms have persisted for 12 weeks or longer, chronic sinusitis may be one possibility. An ENT evaluation can help determine whether sinus inflammation, allergies, nasal polyps, structural narrowing, or another condition is responsible.

Acute Sinusitis vs. Chronic Sinusitis vs. Allergies
Sinus symptoms overlap considerably, which is why patients can spend months assuming they have allergies or repeatedly treating what seems like another sinus infection.
| Feature | Acute Sinusitis | Chronic Sinusitis | Allergic Rhinitis |
|---|---|---|---|
| Duration | Usually less than 4 weeks | 12 weeks or longer | Seasonal, episodic, or year-round |
| Common Symptoms | Congestion, drainage, facial pressure | Persistent congestion or drainage, facial pressure, reduced smell | Sneezing, itching, watery drainage, congestion |
| Nasal Drainage | May be clear, thick, or discolored | May be clear, thick, or discolored | Often thin and watery |
| Itchy Eyes/Nose | Less typical | Less typical | Common |
| Fever | Can occur, particularly with some acute infections | Not typical | Not typical |
| Treatment Approach | Supportive care; antibiotics in selected bacterial cases | Saline irrigation, intranasal corticosteroids and treatment of contributing conditions; procedures for selected patients | Allergen avoidance, antihistamines, intranasal corticosteroids and immunotherapy when appropriate |
Allergic rhinitis and chronic sinusitis are different conditions, but they can overlap and sometimes occur together. Antihistamines may help allergy-driven symptoms such as sneezing, itching, and watery drainage, but they do not address every cause of chronic sinus inflammation.
Likewise, antibiotics may be appropriate for selected bacterial infections but do not correct nasal polyps, structural narrowing, or other noninfectious contributors to persistent symptoms.
What Can Contribute to Chronic Sinusitis?
Chronic sinusitis does not have one universal cause. Several factors can contribute to persistent inflammation and impaired sinus drainage, and some patients have more than one issue at the same time.
Allergic Inflammation
Allergic rhinitis can contribute to nasal inflammation and may coexist with chronic sinusitis. For patients with both conditions, identifying and managing allergy triggers can be an important part of reducing symptoms.
Allergy testing may be recommended when symptoms suggest that environmental triggers such as pollen, dust mites, pet dander, or mold are playing a role.
Nasal Polyps and Structural Narrowing
Nasal polyps are soft, noncancerous growths that develop within the nasal passages or sinuses. Depending on their size and location, they can contribute to obstruction, drainage problems, and loss of smell.
Structural conditions such as a deviated septum can also affect nasal airflow and, in some patients, contribute to difficulty with sinus drainage. An ENT examination can help distinguish structural problems from inflammation alone.
Ongoing Sinus Inflammation
Chronic sinusitis can persist even when there is no active bacterial infection. It is primarily an inflammatory condition, which is one reason repeated courses of antibiotics do not help every patient with long-lasting sinus symptoms.
Identifying whether inflammation, polyps, anatomy, allergies, or another factor is contributing helps the specialist choose treatment based on the actual problem rather than symptoms alone.

How Chronic Sinusitis Is Diagnosed
Symptoms can raise suspicion for chronic sinusitis, but diagnosis requires more than checking boxes on a symptom list.
At Southern California ENT and Allergy Associates, evaluation begins with your symptom history and an examination. Depending on the findings, additional testing may be used to look for objective evidence of inflammation and identify factors contributing to your symptoms.
Nasal Endoscopy
Nasal endoscopy uses a thin scope to examine the nasal passages and sinus drainage areas. It can help identify findings such as polyps, mucosal swelling, drainage, or structural narrowing that may not be visible during a basic nasal examination.
Allergy Testing
When allergic rhinitis may be contributing to persistent nasal symptoms, allergy testing can help identify specific environmental triggers. This information can be useful when deciding whether allergy management or immunotherapy should be part of the overall treatment plan.
Sinus Imaging When Needed
A CT scan of the sinuses may be recommended for selected patients when additional information about the sinus anatomy or extent of inflammation is needed. Not every patient with congestion requires imaging, so the decision depends on symptoms, examination findings, and previous treatment.
Treatment Depends on What the Evaluation Finds
There is no single treatment that is appropriate for every patient with chronic sinusitis.
Medical management may include saline irrigation, intranasal corticosteroids, allergy treatment, or other medications based on the patient’s diagnosis and symptoms. When allergies are an important contributor, targeted allergy management or immunotherapy may also be considered.
For selected patients whose symptoms persist despite appropriate medical treatment and whose anatomy or disease pattern makes a procedure appropriate, minimally invasive options such as balloon sinuplasty may be considered.
The goal is to determine what is contributing to the symptoms first, then choose treatment accordingly rather than assuming that every case of chronic congestion requires antibiotics or a procedure.

Frequently Asked Questions About Chronic Sinusitis
What is the main difference between chronic sinusitis and allergies?
Allergic rhinitis occurs when the immune system reacts to allergens such as pollen, dust mites, pet dander, or mold. It commonly causes sneezing, itching, watery drainage, and congestion.
Chronic sinusitis involves persistent inflammation of the nose and sinuses lasting at least 12 weeks and may cause congestion, drainage, facial pressure, and reduced smell. The two conditions can also occur together.
Can chronic sinusitis go away on its own?
Chronic sinusitis is defined by symptoms that persist for at least 12 weeks, so it behaves differently from a short-lived cold or acute sinus infection. Symptoms may improve and worsen over time, but persistent or recurring problems should be evaluated because treatment depends on the underlying cause.
Many patients are initially treated medically, while procedures are considered only when clinically appropriate.
How do doctors test for chronic sinusitis?
Evaluation typically begins with a medical history and physical examination. Nasal endoscopy may be used to look for inflammation, drainage, polyps, or structural narrowing.
Allergy testing may be recommended when allergic triggers are suspected, while a sinus CT may be used in selected patients when additional imaging is needed.
What happens if chronic sinusitis is left untreated?
Persistent chronic sinusitis can affect sleep, energy, sense of smell, breathing comfort, and overall quality of life. It can also be associated with worse asthma control in patients who already have asthma.
Severe or unusual symptoms, including swelling around the eyes, vision changes, significant facial swelling, or neurologic symptoms, require prompt medical attention.
Are antibiotics effective for chronic sinusitis?
Not always. Chronic sinusitis is primarily an inflammatory condition, and antibiotics are not routinely helpful when there is no bacterial infection.
Antibiotics may be appropriate in selected situations, but they do not treat every cause of persistent sinus symptoms. Repeated antibiotic treatment without understanding the underlying problem may not provide lasting relief.
Schedule a Sinus Evaluation at Southern California ENT and Allergy Associates
Chronic sinus symptoms can gradually become part of everyday life. You start breathing through your mouth, clearing your throat throughout the day, or accepting that your sense of smell is not what it used to be. When those symptoms have lasted for months, it is worth finding out why.
A sinus evaluation at Southern California ENT and Allergy Associates may include nasal endoscopy, allergy assessment, imaging, or additional testing depending on your symptoms and examination findings. Once the cause is clearer, your specialist can recommend treatment based on whether inflammation, allergies, nasal polyps, structural narrowing, or a combination of factors is contributing.
