This blog is for educational purposes only and does not replace professional medical advice or diagnosis. If you have health concerns, consult an AHPRA-registered telehealth doctor or request a medical certificate online if clinically appropriate.

Overview
A blocked nose and an itchy throat often occur simultaneously. They can be caused by allergies, viral infections, dry air, or environmental factors that may irritate your respiratory passages.
These symptoms are usually mild. Most people feel better with simple self-care. But sometimes they may indicate a condition that needs medical attention.
Respiratory symptoms like these are one of the most common reasons Australians see a doctor. This article explains the common causes, simple home care steps, management options, and when to seek medical advice.
What causes a blocked nose and an itchy throat?
These symptoms can have multiple causes. Knowing the likely cause helps you choose the right management plan.
| Cause | Typical pattern | How long it lasts |
|---|---|---|
| Common cold or flu | Sore throat, blocked nose, cough, and tiredness. Symptoms build up, then gradually fade. | A few days to about a week. |
| Allergies (hay fever) | Itchy nose and throat, sneezing, and itchy or watery eyes. Often linked to pollen, dust, or pets. | Can last as long as you’re exposed to the trigger. |
| COVID-19 | Similar to a cold, but may include fever, loss of smell, or shortness of breath. | Usually improves within one or two weeks. |
| Sinusitis | Blocked nose, facial pain or pressure, and thick nasal discharge. It often follows a cold. | Most cases settle within two to three weeks. |
| Dry air or irritants | Itchy or scratchy throat and mild congestion, without other cold or allergy symptoms. | Usually, it eases once you avoid the irritant. |

What can you do at home?
Most mild cases get better with simple self-care at home.
1. Stay hydrated

2. Use a saline nasal spray or nasal irrigation

6. Avoid irritants

- Dust
- Air pollution
- Chemical fumes
If allergies are the cause

When should you see a doctor?
See a doctor if:
- Symptoms last longer than 10 days
- Symptoms keep coming back
- You develop a high fever
- You have facial swelling or severe sinus pain
- You have difficulty swallowing
- Symptoms interfere with your daily activities

When is it an emergency?
If you experience severe, worsening, or life-threatening symptoms, call
000 immediately or attend your nearest Emergency Department
(ED). Examples include:
- Difficulty breathing or gasping for air
- Swelling of the throat, tongue, or face
- Severe allergic reaction (anaphylaxis)
- Chest pain
- Confusion or loss of consciousness
- Persistent high fever with severe illness
Can telehealth help?
Telehealth is a convenient option for appropriate healthcare needs and can
complement in-person healthcare. It is not a replacement for face-to-face
care where a physical examination is required. Telehealth may not be
suitable for every condition; some patients may require an in-person
assessment, testing, or emergency care.
- Assessing your symptoms
- Determining whether symptoms are likely due to allergies, a cold, or something else
- Treatment advice
- Online prescriptions, where clinically appropriate
- Medical certificates, if illness affects work or study
- Referrals for further assessment if needed
Your doctor may recommend an in-person examination if they need to check your
ears, nose, or throat, or if your symptoms suggest something more complex.
