When you feel under the weather, it can sometimes be challenging to pinpoint what's wrong. We've all been there – you're suddenly overcome with a runny nose, persistent cough and a painful headache. It might just be a common cold, but it could also be something worse, like a sinus infection.
Although symptoms of both illnesses tend to overlap, there are a few tell-tale signs that can help you spot the difference. When it comes to the sinus infection vs. cold problem, understanding these key differences is essential to determine the best course of action regarding your treatment.
This article will highlight the differences between colds and sinus infections, take a deeper look at the symptoms of each and help patients understand what treatment options they have for each of these respiratory diseases.

A key element of determining whether you have a cold or sinus infection is understanding each type of illness. While the overlap of symptoms is broad, these are still two very different illnesses. This section will define what both colds and sinus infections are.
What Is a Cold?
The common cold is so widespread and contagious that it's recognized as the single most common cause of doctor visits in the U.S. (roughly 110 million per year) [1]. When you have a cold, it means your body is fighting off an upper respiratory viral infection. There are nearly 200 types of viruses that can cause common cold symptoms [2].
One of the most important distinguishing differences between colds and sinus infections is the method of contamination. Colds can be spread by exchanging contaminated water droplets in the air (commonly through coughing or sneezing) or touching a dirty surface. On average, adults experience two to four colds per year, while infants and young children typically experience six to eight [3]. Certain factors, such as smoking or a weakened immune system, can increase the risk.
What Is a Sinus Infection?
Affecting an estimated 11.6% of American adults, sinus infections develop when the lining of the sinus cavities becomes inflamed and irritated, preventing proper mucus drainage and constricting airflow [4]. When mucus builds up in the sinus passages, it becomes an ideal breeding ground for viruses, bacteria and fungi, which lead to infection. Additionally, allergies, environmental irritants and nasal polyps or growths in your sinuses may increase the risk of developing a sinus infection [5].
When discussing sinus infection vs. cold symptoms, it's important to note that sinus infections tend to be far more severe than the common cold.
Symptoms: Common Cold vs. Sinus Infection
As mentioned, distinguishing between these two illnesses can be challenging for patients and healthcare professionals. Your symptoms are the most helpful clues in determining whether you have a sinus infection or cold. This section will discuss these symptoms in further detail and highlight their main differences.
Symptoms of a Cold
The most common symptoms of a cold include coughing, a sore throat, a runny nose and a mild fever. However, full body aches and other discomfort are sometimes common as well. Symptoms of a cold often appear one to three days after exposure and generally resolve on their own within seven to ten days [6].
No matter the severity of your cold, the symptoms will be the same. The complete list of symptoms includes:
Cough
Sore Throat
Headache
Mucus Buildup
Stuffy Nose
Sneezing
Swollen Sinuses
Fatigue
Low-grade Fever
Symptoms of a Sinus Infection
As mentioned, the symptoms of a sinus infection are generally more severe and can be your best indication when determining if you have a sinus infection or a cold. Along with coughing, sneezing and a feeling of fullness in your ears, common symptoms of a sinus infection include:
Sinus Pressure or Pain Behind the Cheeks and Eyes
Runny, Stuffy Nose for More Than a Week
Constant, Worsening Headaches
Fever
Bad Breath (Halitosis)
Thick Yellow or Green Mucus
Fatigue
Decreased Sense of Smell
Facial Pain
Understanding the Difference Between Cold and Sinus Infection
The duration and intensity of your symptoms can help you determine whether you have a cold or sinus infection. While the symptoms of a cold generally improve after three to five days, a sinus infection will linger far longer or may not resolve at all. You likely have a sinus infection if your symptoms don't settle or improve for more than 10 days [7].
Additionally, your mucus color is one of the most significant differences between colds and sinus infections. Clear, watery mucus is typically a sign of a simple cold. However, a sinus infection will cause your mucus to become thick and green or yellow. You probably have a sinus infection if you experience intense nasal discharge and have difficulty blowing your nose.
How to Treat a Sinus Infection or Cold
Getting the proper treatment as soon as possible is critical to recovery if you get a cold or sinus infection. Cold and flu medications offer relief, but you must visit your doctor if your symptoms become more severe or last longer than 10 days. They may prescribe medicines to help you fully recover.
Cold Treatment
Most people don't require prescription medications to treat a cold, and there's no vaccine or outright cure. Instead, taking over-the-counter pain relievers, decongestants and cough suppressants while your body develops immunity and fights off the infection is essential to recovery. Additionally, following a cold treatment regimen is recommended. This can include:
Getting plenty of restful sleep.
Staying home from work or school.
Drinking fluids.
Quitting or temporarily stopping smoking.
Staying clear of alcohol and caffeine.
Sinus Infection Treatment
If you think you might have a sinus infection, you should see your physician immediately. For sinus infections, treatment usually involves taking prescribed antibiotics, decongestants or anti-inflammatory medications [7]. Sometimes, your doctor may even recommend a saline wash or nasal irrigation to help clear the sinuses.
Over-the-counter cold medications can also help ease your discomfort while you wait for the antibiotics to do their job. To avoid potentially harmful side-effects or medicinal conflicts, be sure to speak to your doctor or pharmacist, or refer to the package insert whenever taking multiple medications at one time
Can a Cold Turn Into a Sinus Infection?
Yes, it's possible that a cold can turn into a sinus infection. Sometimes, a cold can lead to a bacterial infection, causing sinusitis. As mentioned, seeing a medical professional is vital if your cold symptoms last longer than 10 days or if you suddenly feel your symptoms become more severe.
