Urgent care for a sinus infection

Most sinus infections are caused by viruses and get better on their own. A visit is worth it when symptoms are severe, last more than 10 days, or improve and then get worse. Urgent care clinics and online providers both commonly see sinus infections.

Sudden confusion, or dizziness or weakness that doesn’t go away
Trouble breathing
A high fever that doesn’t improve with medicine

If you’re not sure, go to the ER. Find the nearest ER.

What urgent care does for a sinus infection

Questions about how long you’ve been sick and whether you were getting better
An exam of your nose, face and throat
Advice on symptom relief, and an antibiotic only if a bacterial infection is likely

There’s usually no test: providers diagnose sinus infections from your symptoms and an exam, and imaging is only needed in some cases. Antibiotics don’t help viral sinus infections, so a provider may suggest watching and waiting 2 to 3 days first.

Find urgent care near you, with hours and phone numbers.

When an online visit may fit

Because diagnosis is based on symptoms and history rather than tests, a sinus infection is one of the most common reasons for an online visit. A provider can suggest relief and prescribe an antibiotic if it’s appropriate.

An online provider will tell you to be seen in person if your symptoms are severe or unusual.

Common questions

Urgent care for a sinus infection, answered.

General information, not medical advice.

Should I go to urgent care for a sinus infection?

Consider it if symptoms are severe, last more than 10 days, come back worse after improving, or come with a fever lasting more than 3 to 4 days. Milder symptoms usually get better on their own.

Will I get antibiotics for a sinus infection?

Not always. Viruses cause most sinus infections, and antibiotics don’t help those. A provider may suggest waiting 2 to 3 days, or give a prescription to fill only if you aren’t better.

Can a sinus infection be treated online?

Often, yes. Providers diagnose sinus infections from symptoms and an exam, so a video visit can work well. The provider will tell you if you need to be seen in person.

What helps sinus pressure at home?

The CDC suggests a warm compress over the nose and forehead, saline or decongestant nasal spray, breathing steam, and over-the-counter medicines as directed. Ask a provider before giving cold medicines to children.
