Sinus infection vs cold: If you’ve wondered whether that blocked nose and facial pressure is “just a cold” or a sinus infection, you’re not alone. It’s a common mix-up because the symptoms overlap. But they’re not the same. Knowing the difference helps you choose the right care and feel better faster.
What is a cold?
A cold is a mild infection caused by a virus. Many types of viruses can cause a cold, but the most common one is called rhinovirus. Colds are contagious and can spread from one person to another through coughing, sneezing, or touching things like doorknobs or phones. Common cold symptoms include a stuffy or runny nose, a sneezing cough, a mild headache, feeling tired; and a mild fever. A cold starts slowly and goes away on its own within 7 to 10 days.

What is a sinus infection?
A sinus infection (sinusitis) happens when the lining of your sinus cavities gets inflamed or infected. These air-filled pockets sit in your forehead, cheekbones, and behind the nose. When they’re blocked, germs can multiply. Typical symptoms include facial pressure/pain, thick yellow-green nasal discharge, persistent congestion, headache or pain behind the eyes, unpleasant breath, upper tooth pain, and sometimes fever.
Cold vs. sinus: The main differences
| Symptom | Cold | Sinus |
| Cause | Virus | Virus or bacteria |
| Mucus colour | Clear or white | Yellow or green |
| Facial pressure | Rare | Common |
| Tooth or eye pain | Rare | Common |
| Fever | Mild or none | More likely (especially bacterial) |
| Duration | 7 to 10 days | Can last longer than 10 days |
| Bad Breathe | Not common | Often present |
Can a cold turn into a sinus infection?
Yes, it can. Sometimes a cold blocks your sinuses, causing the trapped mucus to become a breeding ground for bacteria. If your cold symptoms last longer than 10 days or if they get worse after five to seven days, it might be a sinus infection.
How can you treat a cold?
Colds are caused by viruses, so antibiotics don’t work. Treat cold symptoms by getting plenty of rest, drinking lots of water, using a humidifier to loosen mucus, and consuming warm drinks like tea or broth.
How to treat a sinus infection?
For most sinus infections, the recommended care looks similar to a cold. Rest, drink plenty of fluids, and use a warm compress on your face to ease pressure. Saline nasal rinses and steam (hot shower or a humidifier) can loosen mucus and relieve congestion. If symptoms haven’t improved by 10 days, or if they worsen (high fever, severe facial pain, swelling, or thick discharge that’s getting darker), see your doctor; antibiotics may be prescribed if a bacterial infection is suspected.

Both can start the same, but key differences help: colds are usually milder and shorter, while sinus infections often bring more facial pressure, thicker yellow/green mucus, and longer-lasting symptoms. The good news: most cases improve with rest and home care. If things aren’t getting better, call your doctor.
