British Scientists Identify New Prolonged COVID-19 Symptom

Scientists from the University of Leeds have uncovered a novel symptom of prolonged COVID-19 characterized by limb reddening, itching, and tingling. This development was reported by The Independent.

As known, most individuals who contract COVID-19 recover within a few days or weeks after the onset of initial symptoms. Up until now, the most common manifestations included severe fatigue, loss of smell, muscle pain, and shortness of breath. Other symptoms encompassed memory issues, chest pain, insomnia, rapid heartbeats, dizziness, joint pain, ringing in the ears, as well as depression and anxiety.

New research by scientists has revealed a previously unknown symptom of long-term COVID-19.

A report published in the medical journal The Lancet describes this new symptom, observed in a 33-year-old man. He sought treatment at a specialized clinic after experiencing periodic "rapid violet discoloration" of his legs for six months. The man noted that while standing, his legs became heavy, accompanied by tingling and itching sensations. He also mentioned that a rash would occasionally appear on his legs, but the enigmatic symptoms would subside when he lay down.

This condition is known as acrocyanosis, or persistent and intense blue or cyanotic skin discoloration. Typically observed on the hands and feet, it can also extend to the nose and ears.

"We have a striking case of acrocyanosis in a patient who had not noticed it prior to being infected with COVID-19. Those experiencing this may not even suspect that it could be a symptom of a prolonged course of COVID-19 and autonomic dysfunction," shared Dr. Manoj Sivan, co-author of the study, clinical faculty member, and honorary consultant in rehabilitation medicine at the University of Leeds.

The study also emphasizes that medical professionals may be unfamiliar with the connection between acrocyanosis and the prolonged course of COVID-19.

"We need to increase awareness of dysautonomia (autonomic nervous system dysfunction) in the context of long COVID so that clinicians have the necessary tools to properly treat patients," the scientist added.

The severity of COVID-19, it is reported, is not linked to the likelihood of developing a prolonged illness, and individuals who initially experienced mild symptoms may still face long-term issues.
