In brief
- Deep exhaustion: Physical and mental fatigue that does not disappear with sleep.
- Cognitive impairment: Concentration and memory disorders ("brain fog").
- Symptom worsening after exertion: Even small efforts often trigger a "crash" (post-exertional malaise).
- Accompanying complaints: Pain, sleep disorders, circulation problems, hypersensitivity to light or sounds.
- Treatment approach: No cure, but stabilisation through pacing, gentle movement, sleep hygiene, stress reduction and medical care.
What is ME/CFS? Understanding the most important symptoms
Chronic fatigue syndrome (CFS) is not imagination or a passing phase.
It is a serious physical illness that can often lead to considerable restriction and, in severe cases, even to the need for care or disability.
The causes are not yet fully understood, but experts often see a connection with viral infections.
The Epstein-Barr virus, for example, or a COVID-19 illness can be possible triggers.
Many patients diagnosed with ME/CFS today have a history of long COVID or post-COVID-19 syndrome.
Probably the most serious symptom, and the decisive one for diagnosis, is post-exertional malaise (PEM), which has also given the fatigue syndrome the name systemic exertion intolerance disease (SEID).
- Post-exertional malaise (PEM): It could be described as a "crash after exertion". Even minimal physical or mental exertion – such as a short walk, a phone call or reading – can result in a massive worsening of all symptoms hours or days later. This deterioration after exertion is a core feature of myalgic encephalomyelitis / chronic fatigue syndrome.
Other main symptoms of the exhaustion syndrome are:
| Symptom category | Description |
|---|---|
| Deep physical and mental exhaustion | Not comparable with normal tiredness, cannot be remedied by sleep |
| Cognitive problems ("brain fog") | Severe concentration and memory disorders |
| Pain | Unexplained muscle, joint or head pain |
| Sleep disorders | Sleep is often not restful despite exhaustion |
| Circulation problems | Dizziness or light-headedness when standing up (orthostatic intolerance) |
| Hypersensitivity | Increased sensitivity to light, sounds or touch |
The difficult path to diagnosis
For many patients with myalgic encephalomyelitis / chronic fatigue syndrome, the path to the correct diagnosis is long and frustrating.
Perhaps you have experienced your profound exhaustion being dismissed as normal tiredness or not taken seriously.
This experience is unfortunately widespread and an essential part of the clinical picture.
The reason for this diagnostic challenge lies in the complexity of the condition.
To this day, there is no specific laboratory test or imaging abnormality that unambiguously proves chronic fatigue syndrome.
The diagnosis is therefore a process of exclusion.
Experts must rule out other diseases with similar symptoms through a careful medical examination and check whether the specific criteria for myalgic encephalomyelitis are met.
This process underlines how important it is to find a doctor or therapist who is familiar with the illness and takes those affected seriously.
The vicious circle: why "pulling yourself together" doesn't work

Well-meaning advice such as "just do some sport" or "pull yourself together" is not only ineffective for people with ME/CFS but harmful.
Trying to ignore the symptoms and force former performance inevitably leads to a vicious circle:
- A person carries out everyday activities despite the symptoms.
- This effort exceeds the greatly reduced load limit and triggers PEM – the "crash".
- A phase of massive symptom worsening follows, which can last days or weeks and is often associated with being bedridden.
- Through the forced inactivity, physical resilience declines further.
- The threshold for the next "crash" becomes even lower.
This cycle is the reason why activating treatment demonstrably causes harm in this illness.
The key to stabilisation is a completely different approach.
Pacing in everyday life: 3 first steps you can implement immediately
While you wait for specialised therapy, there are already strategies that can help you manage your everyday life better and avoid further "crashes".
These first steps of pacing can make a big difference to your capacity and well-being:
- 1. Keep an energy diary: For a few days, note all your activities – including small things like showering, phoning or reading an email. Rate your energy level before and after on a scale of 1 to 10. The goal is not to achieve more but to recognise patterns: which exertion drains you most? When does a delayed worsening of the symptoms occur as a consequence?
- 2. Schedule fixed rest breaks: Plan fixed rest breaks of 15-20 minutes several times a day, during which you lie down – ideally in a quiet, darkened room without distraction. It is important to take these breaks preventively, before the state of exhaustion overwhelms you. They serve recovery and recharging your energy reserves.
- 3. Apply the 50% rule: If you feel you can do an activity for 10 minutes, deliberately stop after 5 minutes. This approach helps you stay within your limits and avoid overload (exertion). It is about adapting your life to the condition, not the other way round.
Body and mind: coping with the illness
Life with a chronic illness like fatigue syndrome is more than just a physical challenge.
The constant restriction, the loss of former capacity and social isolation also represent an enormous emotional burden.
Feelings such as grief, anxiety and frustration are normal reactions to such a life-changing situation.
Acknowledging these feelings is an important step.
Be lenient with yourself and recognise what your body and mind accomplish every day.
For many people, exchange with others affected, for example in support groups, is also a great support.
Knowing that you are not alone can help enormously in coping with daily challenges.
The role of physiotherapy: pacing instead of pushing

Specialised physiotherapy treatment of chronic fatigue syndrome does not aim to train you but to help you manage your energy reserves wisely.
The key word is pacing.
Pacing means respecting your own severely limited energy resources and planning activities so that overload, and thus a "crash", is avoided.
In practice, at NOVUM2 this means:
- Learning energy management: Together we develop a deep understanding of your individual load limits. Activity diaries help identify patterns and the triggers of PEM.
- Planning activities strategically: We help you structure your day so that short activity phases and necessary rest breaks are in balance. The goal is to remain active but always below the critical PEM threshold.
- Easing symptoms: Gentle manual techniques, breathing therapy to calm the nervous system, and gentle mobilisation can help ease pain and maintain mobility without overtaxing the body.
Your path to more stability
Myalgic encephalomyelitis / chronic fatigue syndrome is a complex condition requiring an equally well-thought-out therapy.
Unfortunately, there is no quick recovery, but through an understanding and adapted approach, many patients can achieve stabilisation of their condition and a considerable improvement in their quality of life.
A thorough medical examination and diagnosis are the first step.
What awaits you with us? Our approach in detail

If you decide on treatment at our practice, we want to take away the uncertainty before the first appointment.
Our approach is designed to give you security and understanding.
An initial appointment at NOVUM2 always begins with a detailed conversation.
You and your story are at the centre.
We listen to you closely to understand your individual clinical picture, your load limits and your specific symptoms.
On this basis, we develop a safe, individual therapy plan together.
We work strictly according to the principle "start low, go slow" – meaning we begin at a very low activity level and only increase when your condition safely allows it.
Our goal is to give you tools with which you can stabilise your condition and gradually improve your quality of life.
Get treated
If you recognise yourself in these descriptions, suffer from fatigue syndrome or want to support a relative, an individual treatment plan is the next step.
The NOVUM2 team is trained in the special requirements of ME/CFS patients.
