One of the most common physical symptoms of long COVID-19 is fatigue. Many people report feeling extremely tired and unable to perform normal daily activities. This fatigue can be debilitating and can last for weeks or even months. In addition to fatigue, many people also experience muscle and joint pain, headaches, and difficulty sleeping.

Another common symptom of long COVID-19 is shortness of breath. This can be caused by inflammation in the lungs, which can lead to difficulty breathing and a feeling of tightness in the chest. This can be especially problematic for people who have pre-existing lung conditions, such as asthma or chronic obstructive pulmonary disease (COPD).

Cognitive symptoms, also known as "brain fog", are also commonly reported by people with long COVID-19. These symptoms can include memory loss, difficulty concentrating, and confusion. These symptoms can be especially frustrating for those who have previously been highly productive and have found it difficult to return to their normal routine.

Depression and anxiety are also common among people with long COVID-19. The physical symptoms of the disease, as well as the isolation and uncertainty caused by the pandemic, can take a toll on mental well-being. Many people report feeling overwhelmed, anxious, or depressed.

Symptoms can also affect the skin, eyes, ears, nose, throat and even hair. Hair loss is also a common symptom of long COVID-19 patients. There are over 15 types of symptoms in all, according to materials published by the Centers for Disease Control and Prevention (CDC).

It is important to note that not all people with COVID-19 will experience long-term symptoms, and the severity of these symptoms can vary greatly from person to person. Some people may have only a few mild symptoms, while others may have more severe symptoms that greatly impact their quality of life.
