A blocked nose, facial pressure, headache and cough can make it difficult to know whether you have a common cold or sinusitis. The most useful cold vs sinusitis clues are the overall pattern of symptoms, how long they have lasted and whether facial pain, pressure or reduced sense of smell has become more prominent. A cold usually develops gradually and mainly affects the nose and throat, while sinusitis involves inflammation of the sinuses and often adds facial pain or pressure to nasal blockage or discharge. Symptoms can overlap, so these signs are guides rather than a way to diagnose yourself.
What Does a Common Cold Usually Feel Like?
The common cold is a viral infection that usually comes on gradually over two to three days. NHS guidance lists a blocked or runny nose, sneezing, sore throat, hoarse voice, cough, and feeling tired or unwell among the main symptoms. Some people also develop a temperature, aching muscles, altered taste or smell, and pressure in the ears or face. Most colds can be managed at home and should begin to improve within one to two weeks.
What Does Sinusitis Usually Feel Like?
Sinusitis is inflammation of the sinuses and is common after a cold or flu. Typical symptoms include a blocked or runny nose together with pain, swelling or tenderness around the cheeks, eyes or forehead. Reduced sense of smell, green or yellow nasal mucus, headache, toothache, bad breath, cough and ear pressure can also occur. NHS guidance says sinusitis is common and usually clears by itself, although the symptoms can last longer than an ordinary cold.
Cold vs Sinusitis: Quick Comparison
Cold vs sinusitis is not always obvious in the first few days because both can cause congestion, a runny nose, cough, tiredness and facial or ear pressure. Sinusitis can also begin during or after a cold. The comparison becomes more useful when you look at the whole pattern rather than one symptom in isolation.
| Feature | Common cold | Sinusitis |
| How it starts | Usually gradual over 2–3 days | Often follows a cold or flu; may become more noticeable as sinus symptoms persist |
| Common pattern | Runny/blocked nose, sneezing, sore throat, cough, tiredness | Nasal blockage/discharge plus facial pain/pressure or reduced smell |
| Typical duration | Usually starts improving within 1–2 weeks | Acute sinusitis often takes 2–3 weeks to resolve; NHS says it usually clears within 4 weeks |
| Facial pain / toothache | Can have pressure, but usually not the main feature | More characteristic, especially facial tenderness/pressure or tooth/jaw pain |
| Antibiotics | Do not treat a cold | Usually not needed; bacterial sinusitis is uncommon and requires clinical assessment |
Does Green or Yellow Mucus Mean Sinusitis?
Green or yellow mucus can happen with sinusitis, but mucus colour alone does not prove that an infection is bacterial or that antibiotics are needed. The current NHS England acute sinusitis pathway looks at several features together, including how long symptoms have lasted, whether they worsened after an initially milder phase, fever, persistent purulent discharge and severe one-sided tooth or jaw pain. A pharmacist or other clinician should assess those features rather than relying on mucus colour by itself.
Why Symptom Duration Matters
Duration is one of the most useful cold vs sinusitis clues, but it is not a diagnosis on its own. A cold should usually start improving within one to two weeks. In the NHS England Pharmacy First clinical pathway, acute sinusitis symptoms lasting ten days or less are generally managed with self-care and pain relief, while symptoms lasting more than ten days without improvement are assessed further. The pathway notes that acute sinusitis commonly takes two to three weeks to resolve and is usually viral.
When Could Bacterial Sinusitis Be More Likely?
Most sinusitis does not need antibiotics. The NHS England pathway states that acute sinusitis is usually caused by a virus and is only complicated by bacterial infection in a small minority of cases. Features that can increase suspicion of bacterial sinusitis include marked deterioration after an initially milder illness, fever above 38°C, unremitting purulent nasal discharge and severe localised one-sided pain, particularly over the teeth or jaw. Even then, treatment depends on a clinical assessment and the pathway’s inclusion and exclusion criteria.
What Can You Do for a Cold?
For a straightforward cold, rest, fluids and suitable symptom relief are usually enough. A pharmacist can advise on pain relief and decongestant products where appropriate, taking account of age, pregnancy, other medicines and health conditions. NHS guidance warns that decongestant nasal sprays should not be used for longer than a week because overuse can make congestion worse.
What Can You Do for Mild Sinusitis?
For mild sinusitis, NHS advice includes rest, drinking plenty of fluids, suitable pain relief, avoiding allergy triggers, not smoking and using a salt-water nasal rinse. If you are unsure which treatment is suitable, especially if you take regular medicines or have another health condition, ask a pharmacist before combining products.
When a Pharmacy First Assessment May Help
If your symptoms sound more like acute sinusitis than a simple cold, you may be able to have them assessed through the NHS Pharmacy First service at Biscot Pharmacy. The current NHS England acute sinusitis pathway covers adults and children aged 12 years and over, subject to clinical criteria and exclusions. The pharmacist will assess the pattern and duration of symptoms, check for red flags, and decide whether self-care, treatment under the pathway or onward referral is appropriate. A consultation does not guarantee that a medicine or antibiotic will be supplied.
When Should You Seek Urgent Medical Help?
Seek urgent medical advice if you are very unwell, symptoms are worsening significantly, painkillers are not helping, or you have a weakened immune system. The NHS England sinusitis pathway also highlights serious warning signs such as swelling around the eye, reduced vision, severe frontal headache, signs of meningitis or focal neurological symptoms. Use NHS 111 for urgent advice when appropriate, and call 999 for a life-threatening emergency.
Could It Be Something Else?
Not every blocked nose or facial pressure is a cold or sinusitis. Hay fever and other allergies, migraine, dental problems, nasal polyps and other nasal conditions can cause overlapping symptoms. Recurrent symptoms, symptoms that persist for many weeks, or symptoms only on one side of the face should be assessed rather than repeatedly self-treated.
A Simple Cold vs Sinusitis Decision Check
A practical cold vs sinusitis check is to ask four questions: Did the illness start gradually with mainly nose and throat symptoms? Is facial pain or pressure now a prominent feature? Has your sense of smell reduced? Have symptoms lasted more than ten days without improvement or become noticeably worse after initially being milder? The more the pattern shifts towards persistent nasal symptoms plus facial pain or pressure, the more useful a pharmacist or GP assessment may be.
Conclusion
The main cold vs sinusitis difference is the overall symptom pattern, not one isolated sign. Colds commonly cause gradual nose and throat symptoms and usually start to improve within one to two weeks. Sinusitis often follows a cold and is more likely to involve persistent nasal blockage or discharge together with facial pain or pressure or reduced smell. If symptoms are persistent, worsening or concerning, ask a healthcare professional to assess them rather than trying to diagnose the cause yourself.

Frequently Asked Questions
Can a cold turn into sinusitis?
Sinusitis is common after a cold or flu because inflammation and congestion can affect the sinuses. This does not mean every cold will become sinusitis.
How long should a cold last before I worry about sinusitis?
A cold should usually begin to improve within one to two weeks. Symptoms lasting more than 10 days without improvement, especially with facial pain or pressure, may need assessment.
Does green mucus mean I have a sinus infection?
Green or yellow mucus can occur with sinusitis, but colour alone cannot tell you whether the cause is bacterial or whether antibiotics are needed.
Can a pharmacist assess sinusitis?
Yes. NHS guidance advises people who think they have sinusitis, including children aged 12 years and over, to speak to a pharmacist. Eligibility for Pharmacy First treatment depends on clinical assessment.
Does sinusitis always need antibiotics?
No. Acute sinusitis is usually viral and most people improve without antibiotics. A pharmacist or GP will decide whether any prescription treatment is appropriate.
When should I seek urgent help for sinus symptoms?
Seek urgent advice if you are very unwell, symptoms are rapidly worsening, painkillers do not help, or you are immunosuppressed. Eye swelling, reduced vision, severe frontal headache or neurological symptoms need urgent assessment.
