questions to ask before sinus infection

Overview

A sinus infection, sometimes called sinusitis, is when the tissue lining your sinuses becomes swollen and inflamed. Your sinuses are small, air-filled spaces behind your forehead, nose, cheeks, and eyes. This swelling can trap mucus and make it hard to breathe through your nose.

Yes. Sinus infections are very common, especially after a cold, and most people will have at least one in their lifetime.

Anyone can get a sinus infection, but you are more likely to if you have allergies, nasal polyps, a weakened immune system, or if you smoke.

Causes

Main causes

• Viral infections like the common cold

• Nasal polyps or a deviated septum
• Dental infection that spreads to the sinuses

Risk factors

• Allergies and allergic rhinitis
• Smoking or exposure to secondhand smoke
• Frequent colds
• A weakened immune system
• Structural issues in the nose

When to see a doctor

See a doctor urgently if:

• Symptoms last more than 10 days without improving
• Symptoms get worse after starting to get better
• You have a high fever and facial pain
• You are pregnant, diabetic, or have a weakened immune system

Book a routine appointment if:

• Make a routine appointment to ask questions like: Do I need an antibiotic?
• Ask: What can I do at home to feel more comfortable?
• Ask: When should symptoms start to improve, and when should I check in again?
• Ask: Could my symptoms be from allergies, and would allergy treatment help?

Diagnosis

Your doctor will usually diagnose a sinus infection by asking about your symptoms and looking in your nose. They may press gently over your sinuses to check for tenderness.

Tests that may be done

• Usually no tests are needed
• A nasal endoscopy — a small tube with a camera to look inside your nose
• A CT scan if symptoms are long-lasting or repeated
• Sending a small sample of nasal discharge to a lab if a bacterial infection is suspected
• Allergy testing if allergies are thought to be the cause

What to expect at your appointment

The doctor will examine your nose and face, and may ask you to lean forward to see if pain changes. Use this visit to ask questions like: Do I need medicine? What home care is safe? When should I check in again?

Treatment

Most sinus infections are caused by viruses, so they do not need antibiotics. Treatment focuses on easing your symptoms while your immune system fights the infection. If a bacterial infection is likely, your doctor may talk with you about an antibiotic prescription.

Self-care at home

• Rest and allow your body to recover
• Drink plenty of water and warm fluids
• Use a saline (salt water) nasal spray or rinse — ask your pharmacist how to use it safely
• Place a warm, moist cloth over your face to soothe pain
• Use a humidifier or take steam baths to loosen mucus
• Ask your pharmacist or doctor about safe pain relief options

Medical treatments

Treatment approaches may include a course of antibiotics if a bacterial infection is suspected, steroid nasal sprays to reduce swelling, decongestants for short-term relief, or other medicines to control allergies. Your doctor will choose a plan based on the likely cause, your symptoms, and your health history. Never take medicines not prescribed for you.

When is surgery considered?

Surgery is rarely needed. It might be considered for chronic sinusitis that does not improve with medicine, to remove nasal polyps, or to correct a structural blockage in the nose.

Living with this condition

While you recover, give yourself time to rest and let your body heal. Keep your nasal passages moist, avoid irritants like smoke, and use home comfort measures as needed. If symptoms drag on, speak to your doctor.

Lifestyle tips

• Avoid smoking and secondhand smoke
• Use a humidifier in dry rooms
• Wash your hands regularly to avoid catching infections
• Manage allergies with the help of your doctor
• Use saline rinses regularly if recommended for chronic sinusitis

Diet and exercise

Drink plenty of fluids, especially water, to keep mucus thin. Eat a balanced diet with fruits and vegetables. Gentle exercise, like a short walk, can be helpful if you feel up to it, but rest when tired.

Mental health and emotional wellbeing

Living with repeated or long-lasting sinus problems can feel tiring and frustrating. It is common to feel low or anxious. Talk to your doctor if this is affecting your mood or daily life. If you ever have thoughts of self-harm or are in crisis, contact your local emergency number or crisis line immediately.

Prevention

You cannot always prevent a sinus infection, but you can reduce your risk by avoiding colds, managing allergies, not smoking, and keeping your nasal passages moist.

Vaccines

Ask your provider about the flu vaccine and other routine immunisations. Preventing respiratory infections can help lower your chances of developing a sinus infection.

Screening programmes

There is no routine screening test for sinus infections. Talk to your doctor if you get several sinus infections each year, as there may be an underlying cause to treat.

Complications

If left untreated

• Most sinus infections resolve without treatment
• Rarely, an infection can spread to the eye socket or other nearby tissues
• In very rare cases, it can move into the brain or cause meningitis
• Chronic inflammation can persist and affect quality of life

Long-term outlook

For most people, a sinus infection improves on its own within a few weeks. Even chronic sinusitis can be managed well with the right care, home habits, and support. The outlook is generally very good.
