Is a Nose Burning Sensation a Symptom of COVID-19?

COVID-19 is an extremely transmissible respiratory illness first identified in late 2019 and caused by the SARS-CoV-2 coronavirus.

Most individuals who contract COVID-19 experience mild signs such as coughing, fever, and fatigue. People aged 65 and older and those with preexisting conditions like diabetes or obesity face the greatest risk of progressing to a severe illness.

COVID-19 can produce nasal complaints similar to other upper respiratory illnesses, including nasal congestion or rhinorrhea. Some anecdotal accounts and isolated reports also describe sufferers experiencing a burning feeling inside the nose.

Read on for a closer examination of whether a burning sensation in the nasal passages is commonly associated with COVID-19. We’ll also compare COVID-19 nasal symptoms with those of other respiratory infections and allergic reactions.

Is a burning feeling in the nose an indicator of COVID-19?

A burning feeling inside the nose can be associated with COVID-19, but it is not among the most prevalent symptoms. The literature addressing nasal burning is limited to a few isolated case reports, so the true frequency of this symptom remains uncertain.

What leads to a burning sensation in the nasal passages?

A burning sensation in the nose may result from inflammation of the sinuses due to sinusitis. Sinus infections can be triggered by viruses, fungi, or bacteria.

One August 2020 study  of 1,773 people with COVID-19 reported that 4.1 percent experienced nasal congestion and 2.1 percent had a runny nose. Such symptoms can create sinus blockage that fosters bacterial or fungal overgrowth.

Case reports

Sinus infections appear uncommon among those with COVID-19, although a handful of case reports have documented them.

A study  in the Journal of Surgical Case Reports (March 2021) described a 52-year-old man with COVID-19 who developed an aggressive sinus infection that caused erosion of the sinus floor bone and complications affecting his right eye.

It was not certain whether COVID-19 was the sole cause or a contributing factor; however, negative bacterial and fungal cultures implied that COVID-19 may have been a major contributor.

A February 2021 report  reviewed three critically ill COVID-19 patients who developed fungal sinusitis. Fungal sinus infections carry a high mortality risk in immunocompromised people. All three patients died from other complications related to COVID-19.

Still, most people with COVID-19 do not seem to develop sinus infections.

How COVID-19 targets nasal cells

An April 2020 review  indicates that SARS-CoV-2 likely gains entry to cells via the angiotensin-converting enzyme 2 (ACE-2) receptor. ACE-2 is present at relatively high levels in the nasal cavity as well as throughout the upper respiratory and digestive tracts.

ACE-2 is also expressed in other organs, including the gastrointestinal tract, lungs, blood vessels, and heart.

Within the nose, ACE-2 is most abundant in mucus-secreting goblet cells and ciliated epithelial cells that line the nasal passages.

Researchers have also determined that the virus uses a protease called TMPRSS2 to effectively enter cells. TMPRSS2 has been detected in nasal epithelial cells as well, according to June 2020 research .

Mouse studies show that reducing levels of this protein in mice led to reduced replication of the virus.

Most frequent nasal complaints with COVID-19

A 2021 study  in the American Journal of Otolaryngology found that about one-third of people with COVID-19 report mild nasal symptoms, such as loss of smell or taste.

Reduction or loss of smell and taste are often reported early in the course of COVID-19. One July 2020 study  found 73 percent of participants reported smell loss before diagnosis, and 26.6 percent said it was their first symptom.

Other nasal symptoms associated with COVID-19 include:

• nasal congestion
• runny nose
• postnasal drip
• difficulty breathing through the nose

Common signs of COVID-19

Per the World Health Organization , the most common symptoms of COVID-19 are:

• fever
• dry cough
• fatigue

Less common but still frequently observed symptoms include:

• loss of smell
• loss of taste
• muscle aches
• headache
• sore throat
• nasal congestion
• conjunctival redness
• diarrhea
• skin eruptions

COVID-19 symptoms compared with other respiratory infections and allergies

COVID-19 symptoms overlap significantly with those of other upper respiratory infections and allergic reactions.

Below is a comparison of common symptoms seen with COVID-19, influenza, the common cold, and allergies.

Some distinguishing features may help determine the cause:

• Allergic symptoms often persist for weeks or months and commonly include sneezing.
• Fever and body aches are not typical of allergies.
• Sneezing is not usually a symptom of COVID-19.
• Allergies do not typically cause cough unless postnasal drip is significant.
• Flu and colds rarely produce severe shortness of breath; when present, it is typically less severe than with COVID-19.

When to seek medical care

Most people with COVID-19 experience mild illness. Mild cases can be managed at home by:

• resting adequately
• maintaining hydration
• using over-the-counter remedies like acetaminophen to control symptoms

It’s essential to isolate as much as possible and avoid public spaces.

The Centers for Disease Control and Prevention (CDC)  recommends that most adults discontinue isolation 10 days after symptom onset and once at least 24 hours have passed since fever resolved without using fever-reducing medicines.

Medical emergency If you or someone you care for develops emergency signs of COVID-19, seek immediate medical care. Many hospitals provide separate areas for treating COVID-19 patients and accept walk-ins. The CDC’s list of emergency symptoms includes: trouble breathing; persistent chest pain or pressure; an inability to stay awake or to be awakened; and pale, gray, or blue lips, nails, or skin. Any of these signs warrants urgent evaluation. Note that people with darker skin may find it harder to detect discoloration in lips, nails, or skin—such changes suggest inadequate oxygenation.

Takeaway

A burning feeling in the nose may be associated with COVID-19, but it is not a common hallmark of the infection.

Some people with COVID-19 develop nasal congestion or rhinorrhea. Those conditions can predispose to sinusitis, which may cause inflammation and a burning sensation.

COVID-19 symptoms overlap with those of other upper respiratory infections and allergic conditions. Fever is not a feature of allergies and may point toward a viral infection.

If you suspect you have COVID-19, isolate from others and seek medical attention if you experience severe or worsening symptoms.
