A sinusitis self-assessment test is a structured symptom checklist that compares what you are experiencing against the diagnostic criteria used by clinicians, then tells you whether a medical assessment is warranted. The test scores four cardinal symptoms — nasal blockage, nasal discharge, facial pain or pressure, and reduced sense of smell — alongside how many days those symptoms have lasted. A sinusitis self-assessment test does not diagnose sinusitis. It sorts your symptom pattern into one of four groups: a pattern consistent with sinusitis, a pattern consistent with a common cold, a pattern consistent with chronic disease, and a pattern that points somewhere else entirely.
Before scoring anything, read the emergency warning signs in this article. A small number of sinus symptoms require same-day emergency care and no self-test result should delay that visit.

What Is a Sinusitis Self-Assessment Test?
A sinusitis self-assessment test is a symptom-scoring questionnaire that applies the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 symptom criteria to your own case. EPOS 2020 defines rhinosinusitis as inflammation of the nose and paranasal sinuses producing two or more symptoms, one of which must be either nasal blockage or nasal discharge. A self-assessment test converts that clinical definition into 8 yes-or-no questions plus a duration question, which is why the result is a probability statement rather than a diagnosis.
What the test measures
The sinusitis self-assessment test measures three variables: which symptoms are present, whether at least one of the two mandatory symptoms is present, and how many days the symptoms have lasted. The duration variable carries as much diagnostic weight as the symptom count, because a viral cold and post-viral sinusitis share nearly the same symptom list and separate mainly on time.
What the test cannot do
The sinusitis self-assessment test cannot confirm sinusitis, cannot identify which sinus is affected, and cannot establish whether the inflammation is viral, bacterial, or fungal. EPOS 2020 requires objective confirmation by nasal endoscopy or computed tomography before a definitive diagnosis is recorded. A positive self-test result is a reason to book an appointment, not a substitute for one.
Which Symptoms Does the Sinusitis Self-Assessment Test Score?
The sinusitis self-assessment test scores four cardinal symptoms and four supporting symptoms.The four cardinal symptoms come directly from EPOS 2020: nasal blockage or congestion, nasal discharge, facial pain or pressure, and reduction or loss of smell. The four supporting symptoms — headache, upper tooth pain, bad breath, and low-grade fever — raise or lower confidence in the result but never carry it alone.
Nasal blockage or congestion
Nasal blockage is one of the two mandatory symptoms in the EPOS 2020 criteria, meaning a positive result requires either this symptom or nasal discharge. In sinusitis, blockage is caused by swelling of the mucosal lining rather than by mucus volume, which is why blowing the nose does not clear it. Persistent obstruction on one side only is a specific pattern worth reporting to a doctor, as it is associated with structural causes such as polyps or a deviated septum. Read more about nasal congestion and what drives it.
Nasal discharge, anterior or posterior
Nasal discharge counts whether it runs from the nostrils (anterior) or down the back of the throat (posterior nasal drip). Both directions score identically on the sinusitis self-assessment test. Colour does not change the score, and the reasoning behind that appears in the bacterial section below.
Facial pain or pressure
Facial pain or pressure is a supporting criterion in EPOS 2020, not a mandatory one. The pain follows the affected sinus: the forehead for the frontal sinuses, the cheekbones and upper teeth for the maxillary sinuses, between the eyes for the ethmoid sinuses, and the back of the head for the sphenoid sinuses. Pain that worsens on bending forward is the pattern most specific to sinus origin. The mechanism behind sinusitis facial pain and pressure is mucus that cannot drain through inflamed ostia.
Reduced or lost sense of smell
Reduction or loss of smell is a supporting criterion in adults and one of the most useful discriminators on the test, because it is uncommon in tension headache and in most dental problems. Smell loss occurs when mucosal swelling blocks odour molecules from reaching the olfactory nerves at the roof of the nasal cavity. Smell that has not returned after a cold resolved is a marker of prolonged inflammation, and loss of smell in sinusitis is most persistent in chronic disease with or without nasal polyps.
Supporting symptoms that adjust confidence
Four supporting symptoms adjust confidence in the result: headache, pain in the upper teeth, bad breath, and low-grade fever between 37.2°C and 37.8°C (99°F and 100°F). A headache from sinusitistracks the affected sinus and eases as mucus drains, which distinguishes it from a headache that occurs without any nasal symptom. In children, EPOS 2020 replaces loss of smell with cough as the supporting criterion, so a paediatric self-check scores cough where an adult check scores smell.
How Do You Take the Sinusitis Self-Assessment Test?
Take the sinusitis self-assessment test in three steps: screen for emergency symptoms, answer the 8 symptom questions, then record symptom duration in days. The order matters. Screening for emergency symptoms first prevents a reassuring symptom score from delaying urgent care in the small number of cases where sinus inflammation has spread beyond the sinuses.
Step 1 — Screen for emergency symptoms
Answer this question first: is any of the following present — swelling or redness around an eye, changed vision, a bulging eye, a severe or unfamiliar headache, confusion, or a stiff neck? If yes, stop the test and seek emergency care today. If no, continue to step 2. The full emergency list appears later in this article.
Step 2 — Answer the 8 symptom questions
Answer each question yes or no based on your symptoms right now. Questions 1 and 2 are the mandatory pair, and question 4 is scored only when question 3 is answered yes.
| # | Question | Criterion type |
|---|---|---|
| 1 | Do you have nasal blockage, obstruction, or congestion? | Mandatory (one of two) |
| 2 | Do you have nasal discharge, running from the nose or down the throat? | Mandatory (one of two) |
| 3 | Do you have facial pain, pressure, or fullness? | Supporting |
| 4 | Does that pain increase when you bend forward or lie down? | Supporting |
| 5 | Is your sense of smell reduced or absent? | Supporting (adults) |
| 6 | Do you have a headache in the forehead, cheeks, or behind the eyes? | Supporting |
| 7 | Do you have pain in your upper teeth without a dental cause? | Supporting |
| 8 | Do you have bad breath or a foul smell you cannot explain? | Supporting |
Step 3 — Record how long symptoms have lasted
Count the days from the first symptom, not from the day symptoms became severe. Record the number in one of four bands: under 10 days, 10 days to 12 weeks, 12 weeks or longer, or improved-then-worsened. The scoring section below reads your symptom count against this duration band.
How Do You Score and Interpret Your Sinusitis Self-Test Result?
Score two or more yes answers, with at least one of them being question 1 or question 2, as a symptom pattern consistent with sinusitis. This threshold follows the EPOS 2020 definition directly. The duration band then determines what that pattern most likely represents, producing one of four results.
| Result | Symptom score | Duration | Most likely interpretation |
|---|---|---|---|
| A | 2+ including Q1 or Q2 | 10 days to 12 weeks | Pattern consistent with acute post-viral sinusitis |
| B | 2+ including Q1 or Q2 | Under 10 days | Pattern consistent with a viral cold |
| C | 2+ including Q1 or Q2 | 12 weeks or longer | Pattern consistent with chronic rhinosinusitis |
| D | Fewer than 2, or neither Q1 nor Q2 | Any | Pattern that does not meet sinusitis criteria |
Result A — pattern consistent with acute sinusitis
Result A means the symptom set and the timeline both match acute sinusitis, which EPOS 2020 defines as symptoms lasting less than 12 weeks. Book a medical appointment. Most cases in this band remain viral or post-viral and resolve without antibiotics, but a clinician is the only person able to judge whether antibiotic treatment applies.
Result B — pattern consistent with a viral cold
Result B means symptoms match sinusitis but have not yet lasted long enough to be classified as post-viral sinusitis. EPOS 2020 states that post-viral acute rhinosinusitis should not be diagnosed before 10 days of symptoms unless there is clear worsening after day 5. Continue self-care and repeat the test on day 10.
Result C — pattern consistent with chronic rhinosinusitis
Result C means symptoms have persisted for 12 weeks or longer, which meets the EPOS 2020 duration threshold for chronic sinusitis. Chronic disease is assessed differently from acute disease: it requires specialist evaluation, and often endoscopy and imaging, because structural factors such as nasal polyps or a deviated septum frequently sustain it. Book an ENT appointment rather than repeating the test.
Result D — pattern that does not meet sinusitis criteria
Result D means either fewer than two symptoms are present or neither mandatory symptom is present. Head or facial pain without nasal blockage and without nasal discharge is rarely sinusitis. The differential section below covers the four conditions most often mistaken for it.
How Long Must Symptoms Last Before They Count as Sinusitis?
Symptoms must persist beyond 10 days, or worsen after an initial improvement, before EPOS 2020 classifies them as post-viral acute rhinosinusitis. Duration is the single most decisive variable on a sinusitis self-assessment test because a viral cold produces the same four cardinal symptoms in its first week.
Under 10 days
Symptoms lasting under 10 days and improving are classified as viral rhinosinusitis, the common cold. Antibiotics have no role in this band.
Ten days to twelve weeks
Symptoms persisting beyond day 10 without improvement fall into post-viral acute rhinosinusitis. This is the band where a medical appointment changes management.
Twelve weeks or longer
Symptoms lasting 12 weeks or longer meet the criteria for chronic rhinosinusitis, a separate condition from acute sinusitis with different causes and a different treatment pathway.
Double worsening
Double worsening — also called second sickening — describes symptoms that improve for a few days and then deteriorate again. EPOS 2020 treats this pattern as a marker for possible bacterial infection even when total duration is under 10 days. Report double worsening to a doctor rather than waiting for the 10-day mark.
Can a Self-Test Tell You If Your Sinus Infection Is Bacterial?
No sinusitis self-assessment test can determine whether a sinus infection is bacterial, because no individual symptom reliably separates bacterial from viral disease. Ebell and colleagues pooled 17 studies in a meta-analysis published in the Annals of Family Medicine in 2019 and reported that among patients with clinically suspected acute rhinosinusitis, 51% had imaging-confirmed rhinosinusitis and only 31% had acute bacterial rhinosinusitis. Separately, an analysis of United States ambulatory visits recorded antibiotics prescribed at 82.3% of acute rhinosinusitis visits, far above that 31% bacterial rate.
Discharge colour does not predict bacterial infection
Green or yellow discharge is the most widely believed bacterial marker and one of the least accurate. The American Family Physician evidence review of acute rhinosinusitis states that the colour of nasal discharge does not help distinguish bacterial from viral causes. Discharge changes colour because neutrophils release a green-pigmented enzyme during any inflammatory response, viral infections included.
Findings most associated with bacterial infection
Three findings carried the strongest association with bacterial rhinosinusitis in the Ebell meta-analysis: the clinician’s overall impression, cacosmia (a foul odour detected by the patient), and pain in the teeth. Cacosmia carried a positive likelihood ratio of 4.3 and tooth pain 2.0, which raises the probability of bacterial infection without confirming it. None of the three is decisive alone, which is why the sinusitis self-assessment test records tooth pain and bad breath as supporting rather than mandatory items.
Which Conditions Are Mistaken for Sinusitis on a Self-Test?
Four conditions produce false positives on a sinusitis self-assessment test: the common cold, allergic rhinitis, migraine, and dental infection. Each shares part of the sinusitis symptom set while requiring different treatment, which is why a positive self-test result needs clinical confirmation.
Common cold
The common cold produces nasal blockage and nasal discharge in nearly every case, satisfying the mandatory criterion. Duration separates the common cold from sinusitis: a cold improves within 7 to 10 days, while post-viral sinusitis does not.
Allergic rhinitis
Allergic rhinitis produces nasal blockage, clear discharge, and reduced smell, and it scores positive on symptom count alone. Three features distinguish it: itching of the nose and eyes, bouts of sneezing, and a seasonal or exposure-linked pattern. Discharge in allergic rhinitis stays clear and watery, and symptoms improve when the allergen is removed.
Migraine
Migraine is the most consequential false positive on a sinus self-test. Schreiber and colleagues screened patients at 452 North American primary care sites for the Archives of Internal Medicine in 2004 and identified 2,991 people who had reported at least six self-described or physician-diagnosed sinus headaches in the previous six months. Of those patients, 88% met International Headache Society criteria for migraine, while 84% also reported sinus pressure and 82% reported sinus pain.
Two limitations belong with that figure. The study excluded patients already diagnosed with migraine, patients with radiological evidence of sinus infection, and patients whose headaches came with fever or purulent nasal discharge, so the sample was already filtered toward non-infectious causes. The assessing clinicians also knew the previous diagnoses, and the study was funded by a migraine drug manufacturer, which led reviewers in American Family Physician to conclude that it probably overestimates the true rate of misdiagnosis. The direction of the finding still holds: recurrent headaches without fever and without purulent discharge point toward migraine, and the overlap between migraine and sinus headaches delays correct treatment in some patients for years.
Dental infection
Infection of an upper molar or premolar can spread into the maxillary sinus, which sits directly above the tooth roots. Odontogenic sinusitis produces one-sided symptoms with tooth pain and foul-smelling discharge, and it does not resolve until the dental source is treated. Structural and dental factors are covered in more detail under causes of sinusitis.
What Is the SNOT-22 and How Does It Differ from a Self-Test?
The SNOT-22 is a validated 22-item questionnaire that measures how severely sinonasal disease affects quality of life, scored from 0 to 110. Hopkins, Gillett, Slack, Lund, and Browne published the psychometric validation of the 22-item Sino-Nasal Outcome Test in Clinical Otolaryngology in 2009. A self-assessment test asks whether sinusitis is likely; the SNOT-22 asks how much the disease is costing the patient.
Score range and interpretation
Each of the 22 items is rated from 0 (no problem) to 5 (problem as bad as it can be), producing a total between 0 and 110. Hopkins and colleagues recorded a mean total score of 9.3 in 116 healthy participants during the original validation, which sets the reference point that patient scores are read against. The minimal clinically important difference — the smallest change a patient actually notices — is 8.9 points.
How clinicians use it
Clinicians use the SNOT-22 to track change rather than to diagnose. A score recorded before treatment and repeated afterwards quantifies whether symptom burden actually fell, which is why the instrument appears in surgical outcome studies and in chronic rhinosinusitis trials rather than in first-visit triage.
When Should a Self-Test Result Send You to a Doctor Immediately?
Seek emergency care the same day for swelling or redness around the eye, any change in vision, a bulging eye, severe headache, confusion, stiff neck, or a fever above 39°C (102.2°F), regardless of your self-test score. These signs indicate that inflammation may have spread beyond the paranasal sinuses to the orbit or the intracranial space, and they override every other result on this page.
Emergency signs requiring same-day care
Six signs require emergency assessment: swelling, redness, or pain around the eye; double vision, blurred vision, or vision loss; a bulging eye; a severe headache that differs from your usual headaches; confusion, slurred speech, seizures, or weakness on one side; and neck stiffness that prevents touching the chin to the chest. Orbital and intracranial complications of sinusitis are rare, and they are time-critical when they occur.
Non-emergency signs that still require an appointment
Book a routine appointment for symptoms lasting more than 10 days without improvement, for symptoms that improve and then worsen, for four or more episodes of acute sinusitis in one year, for symptoms lasting 12 weeks or longer, and for one-sided symptoms that do not resolve.
How Do Doctors Confirm Sinusitis After a Positive Self-Test?
Doctors confirm sinusitis through clinical history, nasal endoscopy, and where needed computed tomography, because symptom criteria alone cannot establish the diagnosis. The consultation starts with three questions — what the symptoms are, how long they have lasted, and what the patient attributes them to — which is the same information a sinusitis self-assessment test collects, structured for a clinician.
Nasal endoscopy
Nasal endoscopy uses a thin tube with a camera passed through the nostril to inspect the nasal cavity and the sinus drainage pathways. It identifies the objective signs EPOS 2020 requires: nasal polyps, mucopurulent discharge from the middle meatus, and oedema of the mucosa.
Computed tomography
Computed tomography is the imaging method used to confirm the extent of disease, and it is reserved for cases where endoscopy and history leave doubt or where medical treatment has failed. Plain X-ray is not used for this purpose because it produces both false positives and false negatives. The full pathway is described in how sinusitis is diagnosed.
What Should You Do While Waiting for Your Appointment?
Use saline irrigation, steam inhalation, hydration, and head elevation during sleep while waiting for a medical appointment, and record your symptoms daily. Daily symptom notes matter more than most patients expect: duration and the presence or absence of double worsening are the two variables a clinician cannot reconstruct after the fact.
Symptom relief measures with the lowest risk
Four measures carry a low risk profile: nasal saline irrigation with distilled or previously boiled water, steam inhalation, fluid intake, and sleeping with the head elevated 30 to 45 degrees. Decongestant sprays relieve blockage but must be limited to a maximum of 5 days, because longer use causes rebound congestion known as rhinitis medicamentosa.
Where Nasodren® fits
Nasodren® is a CE 0051 Class IIA medical device, not a medicine, and it does not claim to cure sinusitis. Nasodren® is a 100% natural nasal spray made from Cyclamen europaeum extract that stimulates trigeminal nerve endings in the nasal mucosa, triggering a reflex increase in mucociliary activity and drainage of retained mucus. The safety and efficacy of the extract have been examined in more than 30 published clinical studies, and EPOS 2012 included Cyclamen europaeum with a Level A recommendation. A 2018 Cochrane review of Cyclamen europaeum extract for acute sinusitis, covering 2 randomised trials and 147 adults, concluded that its effectiveness is unknown because neither trial reported the review’s primary outcomes, and recorded adverse events in 50% of the treatment group against 24% on placebo, with no serious side effects and mild nasal or throat irritation the typical complaint. Both the guideline rating and the Cochrane assessment belong in any evaluation of the product. Nasodren® is used once daily, is suitable for adults and children over 5 years old, and requires medical advice during pregnancy, in children under 5, and for anyone taking anticoagulants. A brief burning or sneezing sensation after application is expected and reflects the intended action on the trigeminal nerve.
What Do People Ask Most About the Sinusitis Self-Assessment Test?
How accurate is a sinusitis self-assessment test?
A sinusitis self-assessment test identifies a symptom pattern consistent with sinusitis, not the presence of sinusitis. Ebell and colleagues found that only 51% of patients with clinically suspected acute rhinosinusitis had imaging-confirmed disease, which means roughly half of clinically suspicious cases are something else. Treat any positive result as a prompt to book an appointment.
Can I tell the difference between a cold and sinusitis at home?
Duration separates the two conditions more reliably than any single symptom. A common cold improves within 7 to 10 days, while post-viral acute rhinosinusitis persists beyond day 10 or worsens after an initial improvement. Symptom type overlaps almost completely in the first week, so the calendar is the more useful test.
Does green mucus mean I need antibiotics?
Green or yellow mucus does not indicate bacterial infection and does not by itself justify antibiotics. Discharge takes on colour from an enzyme released by immune cells during inflammation of any cause, viral included. The 2019 Annals of Family Medicine analysis found no clinical finding, including discharge colour, that predicts bacterial origin.
How many symptoms do I need for a positive sinusitis self-test?
Two or more symptoms are required, and at least one of them must be nasal blockage or nasal discharge. This threshold reproduces the EPOS 2020 definition of rhinosinusitis. Two supporting symptoms without either mandatory symptom do not meet the criteria.
Can children take a sinusitis self-assessment test?
Children can be assessed with the same structure, with one substitution: EPOS 2020 lists cough rather than loss of smell as the supporting criterion in children. Paediatric sinusitis is assessed by a doctor rather than managed at home, because symptom reporting is less reliable in young children.
What does it mean if my symptoms improved and then got worse?
Improvement followed by deterioration is called double worsening, and EPOS 2020 treats it as a marker of possible bacterial infection even before day 10. Contact a doctor when this pattern appears rather than waiting for the standard 10-day threshold.
Is a self-test enough to start treatment?
A self-test result is not sufficient grounds to start prescription treatment. Antibiotics require a clinical decision, and the contrast between a 31% bacterial rate in the 2019 Annals of Family Medicine meta-analysis and an 82.3% antibiotic prescribing rate recorded across United States acute rhinosinusitis visits shows what treating on symptoms alone costs.
Key Takeaways: What Does Your Sinusitis Self-Test Result Mean?
A sinusitis self-assessment test sorts your symptoms into one of four patterns and tells you what to do next — it does not diagnose sinusitis. The seven points below summarise how to read your result.
- Two or more symptoms, one of them nasal blockage or nasal discharge, is the threshold that matches the EPOS 2020 definition of rhinosinusitis.
- Duration decides the category: under 10 days indicates a viral cold, 10 days to 12 weeks indicates acute sinusitis, and 12 weeks or longer indicates chronic rhinosinusitis.
- Double worsening overrides the 10-day rule and warrants medical contact whenever it appears.
- Discharge colour carries no diagnostic value, and no self-test can identify bacterial infection.
- Migraine is the most consequential false positive, with 88% of a screened sinus-headache group meeting migraine criteria in the 2004 Archives of Internal Medicine study, a sample that had already excluded patients with radiological sinus infection.
- Emergency signs override every score: eye swelling, vision change, severe headache, confusion, stiff neck, or fever above 39°C (102.2°F) require same-day care.
- Confirmation requires endoscopy or CT, which is why every positive result ends at an appointment rather than at a treatment decision.
This article is for informational purposes only and does not constitute medical advice or a diagnosis. A self-assessment test cannot replace examination by a qualified healthcare professional. If you experience vision changes, swelling around the eye, severe headache, confusion, neck stiffness, or high fever alongside sinus symptoms, seek emergency medical care immediately.
