What is a sinus infection?
- Usual cause
- Viruses, often after a cold
- Most get better
- Without antibiotics
- Antibiotics may help if
- Symptoms last 10+ days or worsen again
- Relief
- Saline rinses, nasal steroid sprays, pain relief
Your sinuses are air-filled spaces behind your cheeks, forehead and eyes. When they become inflamed, usually after a cold, mucus can't drain properly and builds up, causing pressure and congestion.
Viruses cause most sinus infections, and they usually get better on their own. Bacteria cause some, typically when symptoms drag on for more than 10 days or get worse after starting to improve.
Sinus infection symptoms
Common symptoms include:
- Pain, pressure or fullness in the face, worse when bending forward
- Thick yellow or green nasal drainage
- Stuffy nose and reduced sense of smell
- Postnasal drip and sore throat
- Headache or tooth pain in the upper jaw
- Bad breath, tiredness or mild fever
Get urgent care if you have
These can mean the infection is spreading beyond the sinuses:
- Swelling or redness around the eye
- Vision changes or double vision
- Severe headache, stiff neck or confusion
- High fever
When antibiotics may be needed
Providers look at the pattern of your illness, not just how bad you feel:
| Feature | Likely viral | May be bacterial |
|---|---|---|
| Duration | Improving within 10 days | No improvement after 10 days |
| Course | Gradually getting better | Got better, then suddenly worse again |
| Severity | Mild to moderate | High fever with thick drainage or facial pain for 3–4 days |
NoteEven with a bacterial infection, some people improve without antibiotics. Your provider may suggest waiting a few days to see whether symptoms improve before starting treatment.
Treating a sinus infection
Most sinus infections are treated with symptom relief. When antibiotics are needed, your provider chooses the right option for you.
Relief that works
- Saline nasal rinses, using distilled, sterile or previously boiled water
- Steroid nasal sprays to reduce swelling
- Acetaminophen or ibuprofen for pain and pressure, if they're safe for you
- Warm compresses over your nose and forehead
- Breathe in steam from a shower or bowl of hot water
- Decongestant nasal sprays for no more than 3 days, to avoid rebound congestion
