Key Takeaways
- Symptom Duration: A common cold usually improves within 5 to 7 days, while a sinus infection can last for more than 10 days without showing signs of improvement.
- Fever: While a low-grade fever can appear at the start of a cold, a higher, more persistent fever may point to a sinus infection.
- Nasal Discharge: Colds begin with clear, watery mucus that might thicken and change color temporarily. A sinus infection often involves thick, discolored (yellow or green) mucus that persists.
- Facial Pain: One of the most telling signs of a sinus infection in older children is pain, pressure, or tenderness around the eyes, nose, or forehead, which is not a common symptom of a cold.
- Expert Care: When your child's symptoms are severe or long-lasting, it’s time to see a doctor. PT Family Medicine offers trusted, immediate family medicine in PA to diagnose and treat your child. Schedule an appointment for the care they need.
Is It a Cold or Something More?
Every parent knows the sound of a sniffle or cough. It often signals the start of a common cold, which most children experience several times a year. Colds are caused by viruses and typically run their course without much intervention. However, sometimes what seems like a lingering cold might actually be a sinus infection, also known as sinusitis. A sinus infection occurs when the nasal cavities become inflamed and swollen, trapping mucus and allowing germs to grow.
Understanding the key differences between these two conditions is crucial for knowing when to let an illness resolve on its own and when it's time to seek medical care. PT Family Medicine is here to help you navigate your child's symptoms and provide the right treatment.
Cold vs. Sinus Infection Symptoms
While there's a lot of overlap in symptoms, paying attention to their timing, severity, and specific characteristics can help you tell the difference.
| Symptom | Common Cold | Sinus Infection (Sinusitis) |
|---|---|---|
| Duration | Symptoms typically peak within 3-5 days and start to improve. Most colds resolve in 7-10 days. | Symptoms persist for more than 10 days without improvement or worsen after initially getting better. |
| Nasal Discharge | Starts thin and clear, may become thicker and yellow/green for a few days before clearing up. | Consistently thick, discolored (yellow or green) discharge for more than 10 days. |
| Fever | May have a low-grade fever (under 101°F) for the first few days. | Can have a higher, more persistent fever (over 102°F), especially in the initial days. |
| Cough | Usually present and can be wet or dry. | Often a persistent cough, which may worsen at night. |
| Facial Pain | Not typical. General achiness is more common. | Pain, pressure, or tenderness around the eyes, cheeks, nose, or forehead. Children may complain of a 'headache.' |
| Bad Breath | Not a common symptom. | Often present due to post-nasal drip. |
Understanding the Symptom Timeline
The progression of symptoms is one of the most reliable ways to distinguish a cold from a sinus infection.
The Lifecycle of a Cold
A typical cold follows a predictable pattern. It starts with a sore throat and runny nose, progresses to sneezing and congestion, and then gradually fades away. The mucus may change color mid-illness, which is a normal part of the body's immune response and doesn't automatically mean it's a bacterial infection. The key is improvement—your child should start feeling better after the first week.
When a Cold Becomes a Sinus Infection
A sinus infection often develops as a complication of a cold. The virus causes inflammation that blocks the sinuses, trapping mucus. This environment becomes a breeding ground for bacteria, leading to a secondary infection.
You should suspect a sinus infection if your child’s cold symptoms:
- Last longer than 10 days without any improvement.
- Seem to get better and then suddenly worsen (a phenomenon known as 'double sickening').
- Are accompanied by a high fever that lasts for more than a few days.
When to See a Doctor for Your Child’s Symptoms
While most colds can be managed at home with rest, fluids, and over-the-counter remedies, certain signs warrant a visit to a healthcare provider. PT Family Medicine recommends scheduling an appointment if your child experiences:
- Symptoms that last more than 10 days without any sign of improvement.
- A high fever (over 102°F) for several days.
- Severe symptoms, such as a bad headache or significant facial pain.
- Symptoms that improve and then suddenly get worse.
- Difficulty breathing or fast breathing.
A proper diagnosis is key. A provider can determine if the infection is viral or bacterial. While viral infections resolve on their own, bacterial sinus infections may require antibiotics to clear the infection and prevent complications.

Frequently Asked Questions
How can I tell if my toddler has a sinus infection?
For toddlers who can't describe their symptoms, look for persistent thick, colored nasal discharge for over 10 days, a cough that worsens at night, and prolonged irritability. They may also have swelling around their eyes and a fever that lasts more than three days.
Are antibiotics always needed for a sinus infection?
No, not always. Many sinus infections are caused by viruses and will not respond to antibiotics. Even some bacterial sinus infections can resolve on their own. A doctor will evaluate your child's symptoms to determine if antibiotics are necessary.
How can I help my child feel better at home?
For both colds and sinus infections, you can help manage symptoms by encouraging plenty of rest and fluids. Using a saline nasal spray or rinse can help clear congestion, and a cool-mist humidifier can add moisture to the air, making it easier to breathe. For pain or fever, you can use children's acetaminophen or ibuprofen as directed.
Can allergies look like a cold or sinus infection?
Yes, allergies can cause similar symptoms, like a runny nose, sneezing, and congestion. However, allergies typically do not cause a fever, body aches, or thick, discolored mucus. Allergic symptoms also tend to last as long as the child is exposed to the allergen.
