Understanding Post-COVID Conditions

Understanding Post-COVID Conditions

The COVID-19 pandemic has affected millions of people around the world, and while many have been able to recover without complications, some experience lingering symptoms (e.g., fatigue, brain fog, chest pain, shortness of breath) that can persist for several weeks or months—even after testing negative for the virus. At least four weeks after infection is the start of when post-COVID conditions can first be identified. These conditions are commonly known as “long COVID,” “long-haul COVID” or “chronic COVID.”


Post-COVID symptoms can vary greatly from person to person and can last for different periods of time. Some people may experience only mild symptoms that go away quickly, while others may have more severe symptoms that persist for weeks or even months.

One of the most commonly reported post-COVID symptoms is fatigue, which can range from mild tiredness to severe exhaustion. This fatigue can be accompanied by brain fog, a feeling of confusion or difficulty concentrating.

Post-COVID symptoms are broad and can include:

General Symptoms

  • Tiredness or fatigue
  • Symptoms that get worse after physical or mental exertion
  • Fever

Respiratory and Heart Symptoms

  • Difficulty breathing or shortness of breath
  • Cough
  • Chest pain
  • Heart palpitations

Neurological Symptoms

  • Difficulty thinking or concentrating (i.e., brain fog)
  • Headache
  • Sleep problems
  • Dizziness or lightheadedness upon standing
  • Pins-and-needles feelings
  • Change in smell or taste
  • Depression or anxiety

Digestive Symptoms

  • Diarrhea
  • Stomach pain

Other Symptoms

  • Joint or muscle pain
  • Skin changes: rash, tingling, hives, pain and sensitivity
  • Changes in menstrual cycles

It is important to note that while these post-COVID symptoms can be debilitating, they are generally not life-threatening. However, if you are experiencing any of these symptoms and they are causing significant distress or impairment in your daily life, it is important to seek medical attention. While it’s possible people with these symptoms may not receive an appropriate diagnosis, care, or treatment from a provider, people with post-COVID symptoms are encouraged to seek medical care using these tips from the CDC.


The best way to prevent post-COVID conditions is to stay up to date on your COVID-19 vaccinations and boosters. Other ways to prevent COVID-19 infection and lower your risk of post-COVID conditions include avoiding close contact with people who have suspected or confirmed COVID-19 illness, wearing a mask and practicing good hand hygiene, which means using hand sanitizer (containing at least 60% alcohol) or washing your hands with soap and water for 20 seconds.


Doctors and researchers are still learning about post-COVID conditions and the best ways to treat them. It’s important to talk to your doctor if you have been infected or have any symptoms or have any concerns or questions. You may want to seek a professional diagnosis from an experienced provider who can ensure you receive proper monitoring, care and follow-up.

The Bottom Line

Post-COVID conditions can be a frustrating and difficult experience for people who have recovered from the virus. However, by seeking medical attention, making lifestyle changes, and remaining vigilant about your symptoms, it is possible to manage these conditions and continue to live a healthy and fulfilling life.
