If you’ve experienced it, then you know that you can catch a sinus infection during the flu season, or any time, for that matter. You may know immediately if you are dealing with the flu or a sinus infection when symptoms start to appear. But since both conditions share similar symptoms, it can be challenging to tell them apart, particularly in mild cases. Often, it’s not until you’ve become more ill that you can tell the difference. Still, there are key differences between a flu vs sinus infection. Keep reading to find out what they are so that you can take the necessary steps towards recovery.
What Is A Sinus Infection?
Sinus infections, also known as sinusitis, are a respiratory condition that results from an inflammation of the tissues that envelop your sinuses and nasal cavities. Your sinuses are air pockets found in your skull that are responsible for producing mucus that blocks bacteria, dirt, and pollutants from getting into your body. Your sinuses link to your nasal passageway via the osteomeatal complex, which allows for proper drainage, preventing an accumulation of mucus.
When you get a sinus infection, bacteria accumulate in your sinuses. The inflammation stops proper drainage of mucus from your nasal cavities. The mucus buildup creates the ideal environment for viruses and bacteria to thrive and cause an infection. While a sinus infection may develop on its own, it can also stem from a common cold or allergies.
Symptoms of a Sinus Infection
You may experience a range of symptoms when you get a sinus infection. These include:
- Congestion and stuffiness
- Blocked nasal passage
- Green, white, or yellow nasal mucus
- Pressure along your nasal passages
- Pain in the face that usually worsens when you lean forward
- Headache
- Fever
- Pain in your teeth
- Coughing
- Eye pressure and pain
- Bad breath/halitosis
- Sickly and fatigued feeling in general
Symptoms of a sinus infection are similar to those of the flu, but you may not recognize them right away. The reason is that these symptoms tend to be more subtle and build up gradually.
How Does The Flu Affect You?
The flu, also referred to as influenza, is an acute viral respiratory disease caused by infection of the respiratory tract with influenza viruses (seasonal influenza A and B viruses) [1]. It is a contagious infection that, if left untreated, can result in serious complications and even death, especially in vulnerable groups, such as children, the elderly, and pregnant women.
Symptoms of the Flu
Flu symptoms vary from person to person, and can be severe, but some common symptoms include:
- High fever for several days
- Nausea and vomiting
- Sometimes diarrhea
- Low energy
- Appetite loss
- Headache
- Muscle aches
- Sweats/chills throughout the body
- Sore throat accompanied by a dry, irritating cough
- Extreme fatigue/feeling wiped out for days
- Pain or tenderness in the face
- Dizziness
- Coughing
Unlike the common cold, which can cause a sinus infection by causing inflammation of your sinus tissues, resulting in blockage, the flu does not. However, the flu can mimic symptoms of a sinus infection, like a blocked or runny nose, post-nasal drip, headache, and coughing.
Also, while the flu can cause body aches, muscle pain, and chills, these are not symptoms of a sinus infection.
The flu tends to settle in your respiratory system, causing symptoms similar to pneumonia, a cold, and bronchitis.
Duration: Flu vs Sinus Infection
The most notable difference between sinusitis and the flu is how long the symptoms last. The flu typically runs for one to two weeks, while a sinus infection can last much longer.
Symptoms of a sinus infection last for different lengths depending on their type:
- An acute sinus infection can last less than 4 weeks.
- A subacute lasts between 4 and 12 weeks.
- A chronic sinus infection lasts more than 12 weeks. Chronic sinusitis can often worsen without medical attention.
- A recurrent sinus infection involves four episodes for less than 4 weeks with complete symptom resolution between episodes [2].
Sinus infections can also vary in duration depending on your health and your approach to remedying the condition.
Flu vs Sinus Infection: Remedies
On average, the flu can run for roughly 5-7 days, but minor symptoms such as fatigue, achiness, and coughing may continue for a week or two. Barring any underlying medical conditions, you may recover from the flu on your own. Still, you can use certain over-the-counter medicines and pain relievers to help alleviate some symptoms.
Additionally, getting adequate rest, drinking plenty of fluids, and taking antiviral medications (if recommended early by a doctor) can assist in easing symptoms and potentially boost recovery. If you experience shortness of breath, chest pain, or symptoms lasting more than 10 days, visit your healthcare professional.
Sinus infections can also resolve on their own and may clear up with rest, hydration with fluids, and over-the-counter medication. Aspirin and ibuprofen (an anti-inflammatory) are effective options for relieving sinus headaches in adults. Some people may require prescription antibiotics to clear up their sinus infection. In severe cases, antibiotics can prevent serious complications such as meningitis [3].
Some natural home remedies that you can try to help ameliorate your sinus infection by providing immune system support include:
- Eating immune-boosting foods such as garlic, ginger, and honey
- Improve sleep by using a humidifier at night
- Rub food-grade eucalyptus oil on the roof of your mouth, then drink one glass of water
- Place a warm, damp cloth on your face to reduce pressure
If symptoms persist beyond 10 days or worsen, it is a good idea to contact your healthcare provider for proper medical care to address your sinus infection.
Headache or Sinus Infection
When experiencing symptoms like fatigue and sneezing along with headaches, you may not know if it’s a case of a sinus infection or a headache in itself. Headaches and sinus infections tend to share common symptoms, making it difficult to tell them apart.
With a sinus infection, facial pain or pressure in the front of your head and nasal congestion are key features. Also, the headache tends to worsen with leaning forward or lying down. The inflammation and congestion associated with sinusitis can lead to headaches. Remedying the underlying sinus infection can help provide headache relief.
With a headache in itself, you may experience pain or discomfort in your head or neck region, which may be caused by stress, tension, cluster headaches, or migraines. These are characterized by persistent pain or pressure in your head, and pain may be on one or both sides of your head.
Furthermore, headaches may be throbbing or steady, and some people experience sensitivity to light or sound with their headaches. Visit your healthcare provider for a proper evaluation if you’re unsure about the cause of your headache symptoms or if they don’t go away within a few days.
Flu vs Sinus Infection: Fatigue
Both the flu and sinus infection can similarly cause fatigue. Fatigue is common because, with both conditions, your body triggers an immune response to the invading virus or bacteria.
Fatigue that is associated with a sinus infection stems from inflammation and the body’s attempt to fight the infection. This fatigue may remain while the infection persists, usually for a week or more.
The flu causes fatigue because of a systemic viral response in the body. This fatigue usually improves as the flu resolves, typically, within a week. However, sometimes, symptoms tend to be severe or persist, and in such cases, it’s best advisable that you see a healthcare professional for proper evaluation and care.
The Flu, Sinus Infections, Chronic Stress, and Elevated Inflammation
The flu places stress on the body, causing a fight-or-flight response as it responds to the presence of the virus in your body.
The hypothalamus, which together with the pituitary gland and adrenal glands is referred to as the HPA axis, functions together as part of the NeuroEndoMetabolic (NEM) Stress Response System to produce the stress hormone cortisol. The flu’s viral invasion causes your body’s immune system to kick into high gear, leading to an inflammatory response. Cortisol levels remain elevated, attempting to reduce the inflammation.
However, over the long term, elevated cortisol levels can cause an unbalanced immune system, added inflammation, and, in turn, added stress. Your Inflammation Circuit and your entire body will eventually be impacted by this, resulting in a number of symptoms.
The Takeaway
Sometimes it can be unclear if you just have the sniffles or if your symptoms are an indicator of something else. You may not know if you are dealing with the flu vs sinus infection.
It’s never a good feeling being under the weather with symptoms like fatigue, congestion, headaches, or body pain. These symptoms may not go away on their own, but it’s important to know which condition you are troubled with to know how to get the care you need.
