A stuffy nose congestion headache, sore throat, and feeling tired can all occur with both a cold and a sinus infection. Since the symptoms are similar, it may not always be clear as to what you are suffering from. Knowing what is alike and what is different may help in deciding the proper treatment and the decision to seek medical attention.

Most individuals in the United States will experience a mild cold that will simply respond to rest, hydration, and home remedies, but if the symptoms persist, worsen, or improve and then return, you may need to see a doctor. A telehealth appointment is a good place to check in with a doctor online and talk about the symptoms you are experiencing.

What Is the Difference Between a Sinus Infection and a Common Cold?

The common cold is caused by a virus that infects the upper part of your respiratory system. It is most frequently known for a runny/stuffy nose sneezing sore throat, coughing, and mild tiredness.

Infection of the sinuses, also called sinusitis, occurs when the tissues lining the sinuses become inflamed. Sinusitis may follow a viral infection like the common cold, but bacterial infections may be involved in some cases.

The symptoms can look similar, but sinus infections are more likely to cause facial pressure, facial pain, thick nasal drainage, and symptoms that persist or worsen over time.

Common Cold Symptoms

Typical common cold symptoms include:

  • Runny or stuffy nose

  • Sneezing

  • Sore throat

  • Cough

  • Mild headache

  • Mild body aches

  • Fatigue

  • Low-grade fever in some people

Most common colds are caused by viruses and improve without prescription treatment. Antibiotics do not treat viral infections.

Sinus Infection Symptoms

Sinus infection symptoms may include:

  • Nasal congestion

  • Thick or discolored nasal drainage

  • Facial pressure or pain

  • Headache

  • Reduced sense of smell

  • Postnasal drip

  • Cough

  • Sore throat

  • Bad breath

  • Fever in some cases

  • Tooth or facial pain

Sinus pressure may be felt around the forehead, cheeks, nose, or eyes. Some people also notice that symptoms become worse when bending forward.

Sinus Infection vs. Cold: How Can You Tell?

Another very helpful hint is the length of time your symptoms persist and how they evolve.

Coryza is usually more gradual in onset and improves within a few days. Sinusitis may last longer, mostly if the inflammation persists after the initial viral infection.

You should consider speaking with a healthcare provider if symptoms:

  • Last more than about 10 days without improving

  • Become significantly worse after initially getting better

  • Include severe facial pain or pressure

  • Include a persistent or high fever

  • Interfere significantly with normal daily activities

These symptoms do not automatically mean you have a bacterial sinus infection. A healthcare professional can evaluate your symptoms and medical history to determine the appropriate next step.

What Causes Sinus Infections?

Sinus infections can develop when the sinuses become blocked and inflamed. A common cold is one of the most frequent triggers.

Other factors can include:

  • Allergies

  • Nasal polyps

  • Structural problems inside the nose

  • Environmental irritants

  • Certain respiratory infections

When mucus cannot drain normally, it can contribute to sinus pressure and inflammation.

How Are Common Colds Treated?

There is no cure for the common cold, but treatment focuses on managing symptoms while your body recovers.

Depending on your symptoms, supportive care may include:

  • Drinking plenty of fluids

  • Getting adequate rest

  • Using saline nasal sprays or rinses

  • Using a humidifier

  • Taking appropriate over-the-counter medications for congestion, pain, or fever

Always follow medication labels and ask a healthcare professional or pharmacist if you are unsure whether a medication is appropriate for you.

Because most colds are viral, antibiotics generally are not useful for treating them.

How Is a Sinus Infection Treated?

Treatment of a sinus infection is decided based on the cause and severity of the infection.

Many sinus infections are viral and get better with supportive care. Also appropriate may be saline nasal rinses, fluids, and rest, and cold symptoms may be relieved with medications to address congestion or pain.

Prescription treatment may be an option if the health care professional believes that a bacterial infection is likely. Not every sinus infection warrants antibiotics, so they should only be used if a health care professional prescribes them.

Can You Treat a Sinus Infection Through Telehealth?

In many situations, a telehealth appointment can be a convenient way to discuss sinus symptoms with a healthcare provider.

During an online doctor appointment, the provider may ask about:

  • How long you have had symptoms

  • Whether symptoms are improving or getting worse

  • Nasal drainage

  • Facial pain or pressure

  • Fever

  • Cough and breathing symptoms

  • Previous medical conditions

  • Medications you are currently taking

Based on your symptoms and medical history, the provider can discuss appropriate treatment and determine whether you need an in-person evaluation.

Telemedicine is not appropriate for every situation. Severe symptoms or symptoms requiring a physical examination or testing may require in-person medical care.

When Should You See a Doctor for Sinus Symptoms?

Your general practitioner can be contacted if your symptoms are very persistent, very severe or worsening.

Get help right away if you have any of what comes next symptoms: severe headache, swelling around your eyes, vision changes, trouble breathing, confusion, or any other serious or worsening symptoms.

Frequently asked questions

Is a sinus infection worse than a cold?

Not necessarily. Both conditions can cause uncomfortable symptoms. Sinus infections may cause more noticeable facial pressure, facial pain, and prolonged congestion, but severity varies from person to person.

How long does a common cold last?

Many common colds improve within several days to around one to two weeks. Symptoms can vary depending on the virus and the individual.

How long does a sinus infection last?

The duration depends on the cause. Many sinus infections improve with time and supportive care, while persistent or worsening symptoms may require medical evaluation.

Can a cold turn into a sinus infection?

A cold can contribute to sinus inflammation and may be followed by sinusitis. However, not every cold develops into a sinus infection.

Can an online doctor diagnose a sinus infection?

A telehealth provider can evaluate your symptoms, ask about your medical history, and determine whether your symptoms are consistent with sinusitis. Depending on the situation, an in-person examination may still be recommended.

Do sinus infections always need antibiotics?

No. Many sinus infections are viral and do not require antibiotics. A healthcare provider can determine whether prescription treatment may be appropriate.
