Add “COVID tongue” and “fizzing” to the list of possible strange coronavirus symptoms

• Fever or chills

• Cough

• Difficulty breathing or difficulty breathing

• Fatigue

• Muscle or body aches

• Headache

• New loss of taste or smell

• A sore throat

• Nasal congestion or secretion

• Nausea or vomiting

• Diarrhea

But the CDC points out that this does not include all possible symptoms. Keep in mind that this is still a relatively new virus that researchers continue to investigate to understand exactly how it spreads and why some people get very sick and die from it, while others show little or no signs of infection at all.

And some of the other symptoms that patients with COVID-19 have reported are quite unusual, such as swollen or discolored “toes of the COVID” (pseudo-freezing lesions called pernio or hair) or rashes that can range from being irregular to present blisters that look like chickenpox.

Now Madrid researchers are adding some weirder symptoms to this list after examining 666 infected adult patients at a Spanish field hospital last April. According to reports, one in four of these patients noticed what is called “COVID language,” which included uncomfortable oral problems such as: swollen and inflamed tongues with lateral indentations; small bumps or irregular areas on the tongue; and swelling of the mouth or wounds.

In addition, one in 10 of these patients reported suffering from burning sensations in their hands and feet, hives, or other painful inflammation in their limbs.

The research team presented their findings earlier this week, although they were also published as a research letter in the British Journal of Dermatology last September. They warned that the patients analyzed in this study were adults with COVID-19 pneumonia, so these results should not be applied to children or asymptomatic individuals. These symptoms should also not be considered a coronavirus diagnostic tool. Here’s what you need to know about coronavirus testing.

British researcher Tim Spector, a professor of genetic epidemiology at King’s College London, also tweeted about the COVID language earlier this month. “Seeing a growing number of covid tongues and strange mouth ulcers,” he wrote. “If you have a weird symptom or even just get tired and tired, stay home!”

He also said that one in five patients with COVID-19 had “less common symptoms,” such as rashes. “Fizzing” has been another that describes the “electric”, “tingling” or “burning” sensations that some coronavirus patients have complained about Twitter.

Although researchers have not yet determined the cause of these strange symptoms, one theory is that “the immune system is having a very hyperactive response to this coronavirus,” as Dr. Purvi Parikh, a pediatric allergist and immunologist at NYU Langone Health, previously told MarketWatch. “Many of the damage caused by the virus is not really the infection itself; that’s how your immune system reacts. “
