The list of coronavirus symptoms is quite large and growing. The most common are the loss of taste and smell, but there is another that is especially striking due to its rarity: frozen fingers. It feels like inflammation or burning in the fingers, which goes away without special treatment for two to three weeks, reports DarikNews.

This is a skin rash known as perniosis or pernio erythema, which occurs most often in winter due to low temperatures. But this year it begins to appear in spring, mainly among young people.
Esther Freeman, a dermatologist at Boston Massachusetts Hospital, alerted the Washington Post in April after several similar emergency calls related to foot stitches. Ultimately, it turned out that many of the reported patients tested positive for coronavirus.
Most of the patients with so-called “COVID fingers” were asymptomatic or had mild symptoms. Almost all were children or young people between the ages of 20 and 40, a group that is not at risk and has a stronger immune response to the coronavirus.
“Most of the patients were young, healthy, and had a benign clinical course,” said Freeman, who is also a researcher at Harvard Medical School. He added reassuringly: “I don’t want people to think that if they have purple spots on their toes, they will end up with a respirator in the intensive care unit.” The data shows that there are no such consequences. “
Viral rashes are generally not normal, and skin changes are often indicative of a disease of the body. However, these toe rashes surprised the researchers.
According to reports and studies, the first cases appear around April. One of the first pieces of information earlier this month was from a group of French dermatologists who warned of “pseudo-freezing” on the extremities.
At the same time, the journal of the American Academy of Dermatology reported the presence of purple lesions on the foot of a young Belgian who had tested positive for coronavirus and also had more typical COVID-19 symptoms, such as a dry cough and a mild fever.
“The truth is, no one yet knows why this happens and why it happens in the fingers and toes,” said Ebing Lautenbach, director of the Department of Infectious Diseases at the Perelman School of Medicine at the University of Pennsylvania.
Currently, one theory is that some COVID-19 deaths are due to inflammatory problems and clotting problems. The authoritative medical journal The Lancet published in an article that the virus can attack a thin layer of cells that lines the walls of blood vessels and this can lead to rashes and clotting problems.
