The recovery period from COVID-19 varies from person to person. Several studies have found that coronavirus symptoms can sometimes persist for months or even years. SARS-CoV-2 virus can damage the lungs, heart and brain, which can increase the chances of developing long-term health problems.
Further, long COVID symptoms are not only restricted to those who were severely infected in the first place as people with mild symptoms have also reported long COVID symptoms. One of the many symptoms that people usually do not get diagnosed early is Postural Tachycardia Syndrome.
