Add ‘COVID tongue’ and ‘fizzing’ to list of possible possible coronavirus symptoms

• Fever or cold fever

• Cough

• Shortness of breath or breathing problems

• Fatigue

• Muscle or body aches

• Headache

• New loss of taste or smell

• Keelseer

• Congestion or runny nose

• Nausea or vomiting

• Diarrhea

But the CDC notes that it does not cover everyone possible symptoms. Keep in mind that it 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 that they are all.

And some of the other symptoms that COVID-19 patients have reported are quite uncommon, such as swollen or discolored “COVID toes” (called pseudo-freezing lesions, pernio or keel leaves) or skin rashes that can range from uncomfortable to blisters that looks like chicken pox.

Now Madrid researchers are adding more strange symptoms to the list after examining 666 infected adult patients in a Spanish field hospital in April. Reportedly, one in four of these patients noticed what is called ‘COVID tongue’, which includes uncomfortable mouth problems, such as: swollen and inflamed tongues with notches on the side; small lumps or spots on the tongue; and swelling of the mouth or sores.

What’s more, one in ten of these patients reported that they had burning sensations in their hands and feet, hives or other painful swelling in the limbs.

The research team presented its findings earlier this week, although it was also published in the British Journal of Dermatology last year as a research letter. They warned that the patients analyzed in this study are all adults with COVID-19 pneumonia, so these findings should not be applied to children or asymptomatic individuals. These symptoms should also not be considered as a diagnostic tool for the coronavirus. This is 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 COVID tongue earlier this month. “When he saw an increasing number of Covid tongues and strange mouth sores,” he wrote. “If you have a strange symptom or even just headaches and fatigue, then stay home!”

He also said that one in five COVID-19 patients shows “less common symptoms” such as skin rash. ‘Fizzing’ was another one, describing ‘electric’, ‘tingling’ or ‘burning’ sensations that some coronavirus patients complained on Twitter.

While researchers have not yet determined the cause of such strange symptoms, one theory is that ‘the immune system has a very hyperactive response to this coronavirus’, as dr. Purvi Parikh, an allergy and immunologist at NYU Langone Health. , told MarketWatch earlier. ‘A lot of the damage that the virus does is not actually the infection itself; this is how your immune system responds to it. ”
