Setbacks after exertion (PEM)
After physical, mental or sensory exertion, symptoms can worsen and recovery can take time. Some people recognise a delayed dip after an activity; this is often called post-exertional malaise, or PEM.

Long COVID: when recovery, work and income stall together.
Post-COVID, also called Long COVID, can mean that symptoms after a coronavirus infection persist, return or worsen after exertion. Recovery does not always follow a straight line, while care, work and income can all become a system challenge.
This dossier cannot diagnose you. It helps map recurring patterns, questions and possible next steps. Last checked on 22 July 2026.
Recognise it
Not everyone recovers at the same pace
Symptoms and recovery differ from person to person. That uncertainty makes planning, working and explaining yourself harder.
Brain fog: thinking costs more energy
Finding words, concentrating, processing information or dealing with many stimuli can become harder. To someone on the outside that can look like someone is coping, while the effort is invisible.
From care question to coordination question
GP, specialist, paramedic, occupational physician and benefits agencies may each be involved. But who sees the whole picture?
Not being believed is an extra burden
When tests do not give a clear explanation, the focus can shift from what hurts to whether someone has to keep proving or repeating it.
The figures
Long-lasting symptoms are not a marginal issue
According to RIVM reporting in 2024, around 4% of adults said they had symptoms possibly caused by coronavirus for at least three months. The impact on daily life varies.
4% of adults
RIVM reported in 2024 that people described symptoms lasting at least three months after coronavirus. Reported symptoms can persist for a year or longer.
Several care providers
RIVM notes that Post-COVID often involves different providers. That underlines why a clear overview and fixed agreements matter.
The care trap
Where the system can get stuck
The trap is not in one clinician or one decision. It can develop when each separate step seems logical, but nobody protects the whole.
1
Symptoms are treated as a waiting game
Recovery is expected to happen soon, but a clear plan for ongoing or fluctuating symptoms remains absent.
2
Each referral starts the story again
Information and responsibility are divided across providers, while the person has to connect the pieces.
3
Daily life does not wait
Work, income, caring responsibilities and appointments continue while capacity remains uncertain.
4
The burden of proof shifts
The person themselves repeatedly has to explain what is not working and why.
Care, work and income
Reduced capacity for work is not separate from recovery
If Post-COVID affects your capacity to work, you may need to consult your employer, occupational physician, insurance physician and benefits agencies. One plan may exist on paper while real life does not fit it.
Discuss your capacity for work with the occupational physician or insurance physician. Do not wait until work, benefits or other arrangements have already become unmanageable.
Questions for a next conversation
- Which exertion is manageable now, and what is not?
- What does the occupational physician advise, and what has been shared with others?
- When will the plan be reviewed if symptoms worsen?
- Who coordinates the care, work and practical consequences?
- Who keeps the overall overview of care, work and income?
Experiences
Your story can show where the system gets stuck
You do not have to share a diagnosis or medical record. Tell us what you ran into, where you found support, what you missed and what could have helped. Your experience can make a difference.
Frequently asked questions
Frequently asked questions about Long COVID and Post-COVID
Is Long COVID the same as Post-COVID?
Long COVID is a widely used name for symptoms that continue after a coronavirus infection. In the Netherlands, Post-COVID is also used. Symptoms, recovery and the impact on daily life can vary greatly.
What is post-exertional malaise (PEM)?
PEM describes a pattern in which symptoms can worsen after physical, mental or sensory exertion, sometimes with a delay. It is not a diagnosis. Discuss new or persistent symptoms with a clinician.
Where can I turn if Post-COVID also affects work and income?
Discuss your capacity for work and return-to-work with the occupational physician or insurance physician. For the financial effects of illness, benefits or allowances, Zorgfuik refers to Geldfuik.nl.
