Frozen fingers syndrome, new symptom of Covid-19

Cough, fever, loss of taste, muscle pain, fatigue or pneumonia are some of the most common known symptoms of coronavirus. But as the studies progress, new ones are being confirmed. Recently, one has been discovered that manifests itself on the skin. Is he frozen finger syndromeskin lesions that were already known before but that have differences between those that are caused by the virus and those that are not.

According to experts, there are two types of injuries. The first are the most similar to freezing. They turn blue and occur especially in patients who have a serious condition, who are admitted to the ICU. On the other hand, there are the latter, which present redness and can itch or even hurt. They usually appear in young and asymptomatic patients or with mild symptoms.

explains it Esther Freeman, dermatologist at Massachusetts General Hospital (USA). “Never before have I received so many cases with such similar finger injuries,” says the health professional about the appearance of these new symptoms.

On April 16, the Journal of the American Academy of Dermatology published a study on the dermatological effects of the coronavirus that contradicted those early theories that maintained that the virus only affected the lungs. One of the conclusions drawn from the study is that although the loss of smell and taste is one of the first symptoms, Rashes on the toes could be an early indicator of the disease.

These symptoms, without having performed a PCR, may indicate that the patient suffers from Covid. Lesions can last between 2 and 4 weeks. To date, it is unknown why skin lesions have had a greater impact in the first wave than in the second. The cause may be that the virus has mutated, according to researchers.

«The message to the population is not to panic. “I don’t want people to think that if they get purple spots on their toes they’re going to end up on a ventilator in an intensive care unit,” warns Freeman, a researcher at Harvard Medical School and director of the study. .

But, Why do these skin lesions occur in Covid patients? In principle, specialists relate them to coagulation problems that can also be generated as a result of suffering from the disease, both in severe patients and those who suffered from the disease in a mild and even asymptomatic manner. The medical journal ‘The Lancet‘ already published an article last April, in which he explained how the virus could affect a thin layer of cells that covers the walls of blood vessels, thus causing clotting problems as well as skin rashes.
