A mild, uncomplicated sinus problem can often start with an online doctor consultation in Singapore. A doctor can review your symptom pattern, duration, medical history and general appearance over video, then advise on self-care, appropriate treatment or an in-person examination. Teleconsultation cannot look deep inside the nose, examine the eyes closely or perform the tests sometimes needed for persistent or severe sinusitis.
This guide is for adults deciding whether sinus pressure, a blocked nose or suspected sinus infection is suitable for teleconsult. It does not diagnose the cause of your symptoms. If you have swelling around an eye, changes in vision, difficulty breathing or feel severely unwell, seek urgent in-person care.
What is sinusitis?
Sinusitis, also called rhinosinusitis, is inflammation of the lining of the nose and the air-filled sinus spaces around it. Common symptoms include a blocked nose, facial pressure or pain, thick nasal discharge, post-nasal drip and reduced smell or taste. Fever, fatigue, headache, ear pressure and cough can also occur.
Viruses are a common cause of acute sinus symptoms. Allergic rhinitis and structural blockage can contribute, while bacterial infection is more likely in selected patterns such as symptoms that persist or worsen after first improving. Yellow or green mucus alone does not prove that antibiotics are needed.
When can sinusitis be assessed by teleconsultation?
A teleconsult may be a reasonable first step when symptoms are mild to moderate, you can breathe comfortably, and none of the warning signs below are present. It can be especially useful when you need advice about symptom relief, whether your timeline needs review, or whether an in-person GP or ENT assessment is the safer next step.
- Nasal congestion, facial fullness or pressure without severe pain.
- Post-nasal drip, a mild cough or reduced smell alongside cold-like symptoms.
- Symptoms that have not improved as expected and need a clinician's review.
- A familiar, previously assessed pattern with no new warning signs.
- Follow-up questions about a treatment plan already started by a clinician.
During the video call, the online doctor may ask when symptoms started, whether they improved then worsened, where the pain is, whether you have fever, dental symptoms, asthma, allergies or reduced immunity, and what medicines or nasal products you have tried.
What an online doctor cannot check
Video has limits. The doctor cannot perform nasal endoscopy, examine the drainage openings of the sinuses, take a culture, palpate the face in the same way as an in-person examination, or arrange a scan within the call. Persistent, recurrent or unclear symptoms may require a clinic examination or ENT referral.
An escalation to in-person care is not a failed teleconsult. It means the doctor has identified that a hands-on examination or test is important for safe treatment.
When should you skip teleconsult and seek in-person care?
Arrange prompt in-person assessment if symptoms last more than about 10 days without improvement, become worse after initially improving, keep recurring, or include severe facial pain, high fever or persistent discharge. SingHealth also advises medical review for people with asthma, weakened immunity or symptoms not relieved by usual over-the-counter measures.
Seek urgent care for swelling around the eyes or forehead, vision changes, severe or rapidly worsening headache, stiff neck, confusion, marked difficulty breathing or a severely unwell appearance. These are uncommon but may indicate a complication or a different condition that cannot be assessed safely online.
Will an online doctor prescribe antibiotics?
Not automatically. Many acute sinus symptoms are viral and improve with supportive care. Antibiotics help bacterial infections, not viruses, and unnecessary use can cause side effects and antibiotic resistance. The doctor will consider your duration, severity, progression, risk factors and whether an in-person examination is needed before deciding.
Depending on the assessment, advice may include rest, fluids, saline nasal irrigation, suitable pain relief or a nasal treatment. The right option depends on your health conditions, allergies, pregnancy status and current medicines, so ask before starting or combining products.
How to prepare for a sinusitis teleconsult
- Write down the start date and whether symptoms are improving, stable or worsening.
- Record your temperature if you have a thermometer.
- Note where pressure or pain is felt and whether it affects one or both sides.
- List nasal discharge, smell changes, cough, dental pain, eye symptoms and breathing symptoms.
- Have your medicines, allergies and relevant conditions such as asthma ready.
- Join from a quiet, well-lit place and be ready to share your current location.
Use a Singapore-licensed telemedicine provider and live video where possible. HealthHub notes that not every condition can be managed remotely and that the doctor may direct you to a physical examination or tests.
Teleconsult, clinic or emergency care?
- Teleconsult: mild to moderate symptoms, comfortable breathing, no eye or neurological warning signs.
- Clinic or ENT review: symptoms lasting more than 10 days, worsening after improvement, recurrent episodes, severe pain, persistent discharge or an uncertain diagnosis.
- Urgent or emergency care: eye or forehead swelling, vision change, confusion, stiff neck, major breathing difficulty or severe deterioration.

Frequently asked questions
Can an online doctor diagnose a sinus infection?
An online doctor can assess whether your history is consistent with uncomplicated sinusitis and decide on a safe next step. A definite diagnosis may still need an examination inside the nose, culture or scan, particularly when symptoms are severe, persistent or recurrent.
Can teleconsultation prescribe medicine for sinusitis?
Medicine may be prescribed when clinically appropriate after assessment. Antibiotics are not routine because many acute sinus symptoms are viral. The doctor may instead recommend supportive care or an in-person review.
How long should sinus symptoms last before I see a doctor?
Seek medical review if symptoms last more than about 10 days without improvement, worsen after starting to improve, or keep returning. Seek care sooner for severe symptoms or risk factors such as reduced immunity.
Is facial pain always sinusitis?
No. Dental problems, migraine and other conditions can cause facial or head pain. New, severe or unusual pain should not be self-diagnosed as sinusitis.
When is sinusitis an emergency?
Eye or forehead swelling, vision changes, confusion, stiff neck, severe deterioration or major breathing difficulty need urgent in-person assessment rather than another teleconsult.
