A new corona aftereffect that makes your feet turn blue when you stand is reported

If you get a new type of coronavirus infection (COVID-19), you may suffer from the aftereffects of ``

long COVID '', such as a decline in cognitive function that persists for more than two years after recovery, and its impact is greater than is known. Experts warn it's dangerous . A newly published paper reports a rare sequelae in which blood in the veins accumulates in the legs, turning them blue when standing.

A Startling Case of “Blue Legs” Raises Concerns Over Long Covid's Unexplored Symptoms

In a paper published August 12, 2023 in the peer-reviewed medical journal The Lancet, Nafi Iftekhar and Manoj Sivan of the Institute of Rheumatology and Musculoskeletal Medicine, University of Leeds, UK, found that standing for 10 minutes I introduced a case of a 33-year-old male patient who turned blue.

Below are pictures of the patient immediately after standing (left), 2 minutes after standing (middle), and 10 minutes after standing (right).

Six months before the patient's visit to the hospital, she had been suffering from a rapid blue-purple coloration of her legs while standing. In addition to discoloration, there are also symptoms such as heavy feet, tingling, itching, and sometimes a rash. These symptoms subsided when the patient lay down, and the color of her feet returned to normal.

From these symptoms, the man was diagnosed with ``

orthostatic tachycardia syndrome (POTS) ' ', which is characterized by an abnormal increase in heart rate when standing.

“This case is a case of pronounced acrocyanosis in a patient who had never experienced acrocyanosis prior to being infected with COVID-19,” said Sivan. They may feel anxious about what is happening without knowing it is a symptom of dysautonomia or dysautonomia, just as clinicians may not know the link between acrocyanosis and long COVID. '' he said.

Long COVID causes various symptoms that interfere with daily life, including autonomic imbalance, which disrupts the function of the autonomic nervous system that regulates blood pressure and heart rate. In addition, acrocyanosis has been observed in children with dysautonomia due to viral infections, and Sivan et al. I was pointing out to

In light of this case, Sivan said, 'We need a better understanding of dysautonomia in long-term illness, more effective assessment and management approaches, and more research into this syndrome. In doing so, both patients and clinicians can better manage these conditions.'
