Why sinus problems affect the ear
The Eustachian tube opens at the back of the nose, close to the openings that drain the sinuses. Colds, allergies and sinus infections swell the lining there and thicken mucus, so the tube cannot open to balance pressure. Air in the middle ear is absorbed, creating negative pressure that pulls the eardrum inward, which you feel as fullness, muffled hearing or pain. Fluid may then collect. See Eustachian tube dysfunction and sinus infection symptoms.
Symptoms
- Facial pressure around the cheeks, forehead or between the eyes.
- A full, blocked or underwater feeling in one or both ears. See ear fullness.
- Popping or crackling when you swallow or yawn.
- Mild ear ache and muffled hearing.
- Nasal congestion, thick discharge and postnasal drip.
- Headache and tenderness over the sinuses.
- Mild dizziness or imbalance in some people.
- Symptoms worse when bending forward or during flights.
Common causes
- Common cold and viral upper respiratory infection. See stuffy nose.
- Allergic rhinitis or hay fever. See chronic rhinitis.
- Sinus infection (acute or chronic).
- Nasal polyps, deviated septum or enlarged adenoids. See nasal polyps.
- Dry air, smoke and irritants.
- Altitude, flying and diving.
- Reflux that irritates the back of the nose and tube opening.
What helps at home
- Saline nasal rinse or spray to flush mucus and allergens.
- Steam inhalation or a warm shower, and a warm compress over the face and ear.
- Hydration: water and warm fluids thin mucus.
- Swallow, yawn or chew gum to open the tubes.
- Gentle autoinflation (pinch the nose and blow gently), only if there is no ear pain.
- Sleep with your head raised and use a humidifier.
- Avoid smoke and irritants.
- Paracetamol or ibuprofen for discomfort if suitable.
Medicines
- Steroid nasal sprays (fluticasone, mometasone) reduce swelling around the tube; effect takes several days.
- Antihistamines for allergy-related congestion.
- Short-term decongestants: nasal sprays for no more than 3 days; oral decongestants can raise blood pressure.
- Antibiotics only for suspected bacterial sinusitis or ear infection, as advised.
- Oral steroids in selected cases.
- Ask a pharmacist if you have high blood pressure, glaucoma, heart disease or take other medicines.
Flying and diving with sinus and ear pressure
Pressure changes worsen blocked sinuses and tubes, sometimes causing severe pain (barotrauma). If you must fly, use a decongestant spray shortly before descent if appropriate, swallow, yawn and chew frequently, and stay awake during descent. Avoid diving with congestion. See your doctor if pain or blockage persists after landing.
Children
Children have shorter, more horizontal Eustachian tubes and often have enlarged adenoids, so colds easily lead to ear problems. Look for tugging at the ears, irritability, hearing difficulties, speech delay and recurrent infections. Saline spray and allergy control help; persistent fluid or infections need paediatric or ENT review. Avoid cold medicines in young children.
When to see a doctor
- Symptoms lasting more than 10 days, or worsening after improvement.
- Severe facial or ear pain, high fever.
- Ear discharge, hearing loss or dizziness.
- Swelling, redness around the eye or ear: urgent.
- Repeated sinus or ear infections.
- One-sided symptoms, bleeding or reduced smell.
- Persistent blocked ear for more than 3–4 weeks.
Three common situations
A cold followed by a blocked ear and cheek pressure: saline, steam, steroid spray and time.
Allergy season with ear fullness and itchy nose: antihistamine and nasal steroid.
A person with sinus pain, fever and a swollen eyelid: urgent care.
How to use steam and rinses safely
Steam can loosen mucus and ease pressure, but hot water causes scalds, so use a warm shower or lean over a bowl of hot, not boiling, water with a towel over your head for 5–10 minutes, keeping your face at a safe distance. Do not use steam for young children. For saline rinses, use distilled, previously boiled and cooled or sterile water, never tap water, because rare but serious infections have been linked to unsafe water. Clean the bottle or pot after each use, rinse with the head tilted forward and breathe through the mouth. Stop if rinsing hurts or the ear feels worse.
How long should pressure last?
Pressure from a cold usually settles in 7–10 days as the nasal lining recovers. Allergy-related pressure lasts as long as exposure continues. If it persists beyond 10 days, comes back repeatedly or is accompanied by high fever or severe pain, a doctor can examine the nose, sinuses and ears and decide whether a nasal steroid, antibiotics, allergy testing or a scan is needed. Chronic sinus disease that lasts more than 12 weeks deserves an ENT assessment, with a nasal endoscopy to look for polyps, swelling or a structural problem.
Key points to remember
Sinus and ear pressure share one cause: swelling that blocks the Eustachian tube. Rinse, humidify, use a steroid spray or antihistamine and give it time. See a doctor for persistent, severe or red-flag symptoms. Our ENT team can examine your nose, sinuses and ears.

Questions about sinus and ear pressure
These answers are general information and do not replace an examination or individual medical advice.
Can a sinus infection cause ear pressure?
Yes; swelling blocks the Eustachian tube, causing a clogged or full ear.
How do I relieve ear pressure from sinus congestion?
Saline rinses, steam, a steroid spray, hydration, swallowing and yawning.
How long does it last?
Often 1–2 weeks with a cold; longer if infection or allergy persists.
Do I need antibiotics?
Usually not; most are viral.
Is it safe to fly with sinus and ear pressure?
Try to avoid flying with severe congestion; use precautions if you must.
When is it an emergency?
With eye swelling, severe headache, stiff neck, confusion or sudden hearing loss.
