Many people experience extreme tiredness, or fatigue, as a symptom of COVID-19. You may feel too physically exhausted to get out of bed or too mentally exhausted to read or hold long conversations. Energy levels tend to bounce back as you recover. However, in some cases, post-acute COVID-19 syndrome (also known as PACS or long-COVID) may develop, and the fatigue can linger for weeks or months. This can be particularly stressful and frustrating if you’re eager to get back to your normal routine and responsibilities.
