Sinus infection symptoms usually include facial pressure, a blocked nose, thick coloured mucus, and a headache that gets worse when you bend forward. Most cases clear up on their own within ten days. You should see a doctor if symptoms keep getting worse after improving, or come with a high fever and severe pain.

What a Sinus Infection Actually Is
Your sinuses are small air-filled spaces behind your forehead, cheeks, and eyes. When their drainage channels swell and block, mucus cannot drain.
Doctors call this sinusitis. It can be viral or bacterial, and the two look similar at the start. A viral infection often follows a common cold. The symptoms of viral and bacterial sinusitis can look similar at the start. Sinusitis is also known as rhinosinusitis.

The Most Common Sinus Infection Symptoms
The signs of a sinus infection tend to build over a few days rather than appear all at once. Watch for this cluster:
- Pressure or pain around the forehead, cheeks, or bridge of the nose
- A blocked or stuffy nose that will not clear
- Thick yellow or green mucus from the nose or down the back of the throat
- A dull headache that worsens when you lean forward
- Reduced sense of smell and taste
- Sore throat from postnasal drip
- Cough that is worse at night
- Fatigue and a general feeling of being unwell
- Bad breath or a sour taste in the mouth
Some people also run a mild fever. Children may be fussier than usual and rub their faces. Facial pressure or pain can occur around the forehead, cheeks, or bridge of the nose.
A symptom log can help you track changes over several days. Daily tracking is also useful in mobile health apps. The accuracy of fitness trackers depends on what they measure.
How Long Symptoms Should Last
Sinus infection symptoms can vary in how long they last.
Watch for these patterns:
- Improving then worsening. You feel better, then symptoms return or worsen.
- Persisting past ten days. Symptoms that persist without improving may be discussed with a doctor.
Colds and sinus infections overlap. Track how long symptoms last and whether they are improving. Viral infections, including those caused by Rhinovirus, commonly begin with cold symptoms.

When to See a Doctor
Book an appointment if any of these apply to you:
- Symptoms last more than ten days without improving.
- Symptoms improve, then return or worsen.
- You have a fever above the range your doctor considers normal for your age.
- Facial pain is severe or steadily getting worse.
- Symptoms keep coming back several times a year.
- You notice swelling around the eyes, forehead, or cheeks.
- You have asthma, diabetes, or a weakened immune system.
Some situations need urgent care rather than a routine visit. Go straight to emergency services if you have swelling or redness around an eye, vision changes, double vision, severe confusion, a stiff neck, or a headache that is suddenly the worst of your life.
A doctor can usually diagnose sinusitis from your history and an exam.
What Happens at the Appointment
Your doctor may ask about your symptoms and examine your nose and sinuses. They may ask whether you have used a saline rinse or taken an antihistamine. A saline rinse is a form of nasal irrigation.
A doctor can discuss treatment options based on your symptoms. For a viral infection, advice usually focuses on rest, fluids, and symptom relief. Saline rinses, steam inhalation, a humidifier, and warm compresses) may ease symptoms. Check labels before combining cold remedies and pain relievers.

Mistakes People Make With Sinus Symptoms
Antibiotics are not needed for most sinus infections. Other common missteps include:
- Waiting too long with clear warning signs. Eye swelling or a stiff neck is not a wait-and-see situation.
- Stopping prescribed medication early because you feel better.
- Using decongestant sprays for more than a few days.
- Ignoring repeat infections. Frequent sinusitis can point to nasal polyps, allergies, or a structural issue.
- Skipping the follow-up when symptoms do not fully resolve.
Keep your own records if you are managing other conditions. The numbers you collect are useful to share with a professional. Learn how accurate fitness trackers are.
Preventing Future Sinus Infections
You can lower the chance of a sinus infection following a cold.
- Wash your hands often, especially during influenza season.
- Stay hydrated and avoid cigarette smoke and other irritants.
- Manage allergies and use a saline rinse during colds.
If sinus infections recur, ask your doctor whether allergies or nasal polyps might be involved.
Sinus Infection Symptoms FAQ
How do I know if my sinus infection is bacterial or viral?
You usually cannot tell on your own, and it does not matter much at the start. The timeline is the best clue. Symptoms that last beyond ten days or worsen after improving point more toward a bacterial cause, which is when a doctor may consider antibiotics.
Can a sinus infection go away without antibiotics?
Yes, most do. Viral sinus infections clear up within about a week to ten days with rest, fluids, and symptom relief. Antibiotics only help bacterial cases, and even some of those resolve without them.
When should I go to the emergency room instead of my doctor?
Go to the emergency room if you have swelling or redness around an eye, vision changes, severe confusion, a stiff neck, or a sudden severe headache. These signs suggest the infection may have spread, and they need immediate assessment.
Are sinus infections contagious?
Sinusitis can occur after a common cold.
What if my symptoms keep coming back?
Your doctor may check for allergies, nasal polyps, or structural problems in the drainage channels.
