Sinus Infection, the Flu and the Common Cold: Know the Difference

Sniffles, sneezes and sore throats are all common signs of colds, sinus infections and the flu. These diseases affect millions of Americans each year. In fact:

Treating these conditions is challenging enough, but because they have so many similar symptoms, how can you tell them apart? Knowing the difference is important because it can determine the best course of treatment and home care strategies.

We’ve provided this handy guide to help you. First, we look at the common symptoms of each illness and then examine the distinct differences between them.

What are the symptoms of a sinus infection?

 Symptoms of a sinus infection include:

  • Nasal congestion
  • Pain and swelling around the eyes, cheeks, nose or forehead
  • Pain that gets worse when leaning or bending over
  • Yellow or green discharge
  • Headache
  • Earache or sense of pressure in the ear
  • Bad breath
  • Fatigue
  • Fever

Chronic sinus problems are often caused by allergens although sometimes they may be caused by structural problems within the nose.

What are the symptoms of the common cold?

Cold symptoms include:

  • Sore throat
  • Sneezing
  • Watery eyes
  • Runny nose
  • Headaches
  • Coughing
  • Body aches

There is no cure for the common cold, and unless you have a compromised immune system, you should fully recover within 7 to 10 days.

 

What are the symptoms of the flu?

Flu symptoms include:

  • Chills
  • Cough
  • Fever (although some with the flu will not have a fever)
  • Runny nose
  • Fatigue
  • Muscle and body aches

 

How can you tell the difference between a sinus infection, the flu and the common cold?

You can examine the following principles to help you determine the differences among these common conditions.

1. ARRIVAL OF SYMPTOMS

Colds and sinus infections tend to build up and develop over time. The flu can develop within a few hours.

2. LENGTH OF SYMPTOMS

Sinus infections can last for more than a week. A cold will usually “peak” after three to five days before showing improvement. A reasonably healthy person will recover from the flu within two weeks.

3. FACIAL PAIN OR PRESSURE

Pain and pressure, particularly around the eyes, is indicative of a sinus infection.

4. FEVER

A fever is typical of the flu or a sinus infection. Colds do not produce a fever.

5. SWEATS/ CHILLS

Sweats and chills are indicative of the flu.

6. NASAL DISCHARGE

Sometimes the color of the nasal discharge gives a hint at the underlying problem. Clear mucus signifies a cold, while yellow or green indicates a sinus infection.

Symptoms that require immediate attention

Regardless of whether you have a sinus infection, a cold or the flu, if you are experiencing any of the following symptoms, you should contact your doctor as soon as possible:

  • A severe, unrelenting headache
  • High fever
  • Confusion
  • Double vision
  • Stiff neck
