At a glance
What patients feel
Chronic pain and weakness, muscle aches, difficulty concentrating, memory problems, and headache — sometimes for weeks or months after the acute infection.
Who is most affected
Patients with pre-existing chronic disease — hypertension, diabetes, viral hepatitis, autoimmune conditions — have longer and more intense post-COVID symptoms.
Follow-up window
Primary follow-up starts three weeks after the first symptoms and continues up to twelve weeks, coordinated across neurology, rheumatology, internal medicine, cardiology, chest medicine, and rehabilitation.
Musculoskeletal and neurological symptoms
The symptoms of the musculoskeletal system after COVID-19 infection can last for weeks or even months. They include chronic pain and weakness, difficulty with concentration and memory, muscle pain (myasthenia), headache, and other complaints.
Patients often describe the pain as if their body has been run over. This clinical picture is known medically as *myalgic encephalomyelitis* or *chronic fatigue syndrome*.
Symptoms are worse in patients with chronic disease — hypertension, diabetes, viral hepatitis, immune disorders, and others. Alongside the muscular weakness, there is a distinct period of exhaustion and loss of focus that follows even minor exertion, such as walking a short distance. This is what is known as **post-exertional malaise**.
Psychological effects
A small proportion of recovering patients will develop excessive irritability, depression, and post-traumatic stress symptoms.
Treatment combines medication, psychological intervention, and a graduated increase in physical exercise — with the pace of progression chosen carefully to preserve the patient's energy levels rather than exhaust them further.
What follow-up studies show
In a study of 180 patients followed up after severe COVID-19 infection, 87.4% reported that some symptoms — chronic fatigue and shortness of breath among them — persisted for at least a month, regardless of their baseline before infection.
It is worth noting that patients recovering from community-acquired pneumonia (CAP) show the same pattern of symptoms, so these post-infection complaints are not exclusive to COVID-19.
Primary care after infection
COVID-19 is a multi-system disease, so follow-up is shared across several specialties: neurology, rheumatology, internal medicine, cardiology, chest medicine, and rehabilitation.
We begin primary follow-up three weeks after the first symptoms appear, continuing up to twelve weeks. It includes a full blood work-up and inflammatory markers — ESR, CRP, ferritin, and troponin.
For patients whose infection required admission to intensive care, a chest X-ray at twelve weeks is essential to check whether the disease is regressing or progressing. Patients with visible lung damage — identified on X-ray and by pulse oximetry — are followed up jointly with the chest medicine and rehabilitation units.
Psychological support and post-infection care are an important part of the recommendation, because they raise the body's immunity and contribute directly to recovery.
