Chronic Pain: Understanding Persistent Pain and Treatment Options

Chronic pain generally means pain that persists or recurs for more than three months. The distinction is mainly about duration rather than severity: moderate pain can be chronic, and very intense pain can still be acute.

Chronic pain does not take one single form. It can be:

It can appear after an injury or an operation, accompany osteoarthritis, a spinal problem, a nerve injury, an inflammatory disease or another medical condition. In some people, no single structural diagnosis explains the entire pain experience.

Pain medicine now distinguishes two broad situations. The distinction helps explain why two people living with persistent pain do not need the same approach.

Pain remains linked to an identifiable condition that stays clinically relevant: osteoarthritis, an inflammatory disease, cancer or cancer treatment, a nerve injury or disease, persistent musculoskeletal pathology, or the consequences of surgery or trauma.

In these situations the underlying disease continues to be followed and treated in its own right.

In other cases chronic pain becomes a health condition in its own right and cannot be adequately explained by another diagnosis alone.

This does not mean the pain is imaginary, that it is psychological by default, that nothing is wrong, or that the only option is to accept it.

Pain is a protective experience produced by the nervous system in response to perceived threat. After a recent injury, pain and tissue damage often correspond reasonably closely.

When pain persists, that relationship becomes less direct. Pain intensity is not a direct measurement of:

This does not mean tissue pathology is irrelevant. Structural disease can absolutely contribute to chronic pain. The key point is that the relationship between test findings and the pain a person experiences is not always one to one. We describe the same principle on our back pain page.

Pain medicine describes three broad mechanisms. They are not diagnoses to make on your own, and more than one can be present in the same person.

This is pain associated with actual or threatened injury to non-neural tissue and activation of nociceptors.

This does not mean osteoarthritis pain is purely nociceptive. In some people other mechanisms contribute to the picture as well.

This is pain caused by a lesion or disease of the somatosensory nervous system. It has a dedicated page on this site.

This term describes pain associated with altered nociception where there is no clear evidence that ongoing tissue damage activating nociceptors, or a lesion or disease of the somatosensory nervous system, fully explains the symptoms.

Not every person with widespread pain has nociplastic pain, and this page cannot diagnose fibromyalgia. The nervous system is not broken and the brain is not inventing pain: the processing of pain information is altered.

Many situations involve more than one mechanism at the same time. Someone may have tissue-related joint pain, a nerve component and increased sensitivity together. Recognising this mixture avoids overly simple explanations and guides care better.

There is no single explanation. What contributes to persistence differs from person to person and may include:

These are not a checklist of causes. They are factors that may contribute to symptoms, and their relevance is judged case by case.

The fact that sleep, stress or emotional health can influence pain does not make the pain psychological.

No. Pain is a real sensory and emotional experience involving the nervous system.

Thoughts, emotions, sleep, stress, previous experiences and context can influence how pain is processed. That is true of pain generally, including after a recent injury. It does not make pain imagined or voluntary.

Equally, nervous-system involvement is not a reason to ignore structural or inflammatory contributors when they are present.

Yes, and this is common.

MRI, X-rays and blood tests answer specific biological questions. They do not directly measure the experience of pain or every aspect of pain processing.

The next step depends on the clinical picture. For the mechanisms in more depth, our Knowledge Centre article explains why pain becomes chronic.

Sleep and pain influence each other in both directions. Pain can make falling asleep harder and cause night-time waking. Poor sleep can in turn increase pain sensitivity and make recovery and coping more difficult.

During the consultation we therefore ask about:

Poor sleep on its own does not cause chronic pain, and improving sleep does not cure pain. Sleep remains clinically relevant and worth addressing.

Persistent pain often changes how people move. Some become much less active because movement hurts or feels unsafe. Others repeatedly exceed their current capacity and experience symptom flares.

The objective is neither complete rest nor pushing through everything. Depending on the situation, treatment may involve:

Movement is neither a punishment nor a cure. It can sit alongside medical care, physiotherapy and Centre Algos treatments. For broader joint and muscle symptoms, our musculoskeletal pain page goes into more detail.

Fluctuation is part of daily life for many people living with persistent pain. A flare does not necessarily mean new damage.

It can be influenced by:

A significant and unusual change should not automatically be dismissed as a flare. New neurological symptoms, trauma, fever or other warning signs call for medical reassessment.

Some people living with persistent pain also describe marked fatigue, reduced concentration, non-restorative sleep or a sense of mental fog. These symptoms have a dedicated page.

These symptoms can interact with pain and with everyday functioning. Not everyone with chronic pain experiences them, but when they are present they belong in the assessment.

Assessment does not begin by choosing a treatment. It begins with understanding the situation.

At Centre Algos we consider:

We also consider whether the picture suggests nociceptive, neuropathic, nociplastic or mixed mechanisms. This is a clinical orientation, not a definitive classification of every pain.

Not automatically. Testing should answer a clinical question.

Depending on the history and previous investigations, appropriate next steps may involve:

This does not mean every person with chronic pain has a hidden biological abnormality, nor that normal routine tests will necessarily be followed by an advanced test that provides the answer. We do not order tests as a fishing expedition.

In selected patients, broader biological factors may be relevant to general health, nutritional status, energy and recovery, metabolic health or other symptoms accompanying the pain. Where the clinical history gives a reason, targeted laboratory assessment may help clarify whether such factors deserve attention. This is the field of functional biology and micronutrition.

We do not claim that micronutrient deficiencies explain most chronic pain, or that correcting a laboratory value removes pain. We do not hand out a standard supplement list, and not everyone needs extensive laboratory testing.

People living with chronic pain may use analgesics, anti-inflammatory medicines, medicines targeting neuropathic pain or other condition-specific treatments. Depending on the diagnosis and the person, medication may have an appropriate role.

At Centre Algos:

Chronic pain care can involve several disciplines, depending on the condition:

Not everyone needs a multidisciplinary hospital pain programme. Centre Algos does not position itself against Swiss pain centres: our work complements appropriate medical care rather than replacing it.

Psychological approaches, relaxation, breathing techniques or mindfulness can help some people manage aspects of chronic pain. Breathing techniques have their own page at Centre Algos.

Offering a psychological approach never implies that pain is imaginary. These approaches are optional supportive options, chosen together with you, not core treatment for everyone.

We do not offer every treatment to every person. The choice depends on the clinical picture and is discussed during the consultation.

Percutaneous hydrotomy may be considered at Centre Algos for selected persistent or recurrent pain presentations, particularly when the clinical picture involves relevant musculoskeletal, joint, tendon, back or disc-related symptoms. Whether it is appropriate depends on the individual clinical situation and is discussed during the consultation.

Naturopathy at Centre Algos does not mean looking for a natural painkiller. It provides a framework for considering sleep, nutrition, physical activity, recovery, stress, broader health, medication and supplements, and individual habits, where these are relevant to the pain picture.

Our dedicated article sets out what role naturopathy can play in chronic pain.

Phytotherapy may be considered as a supportive component of an individual treatment strategy. Selection depends on the clinical situation, the symptoms, current medication and other treatments. It does not replace medication and does not regenerate tissue.

Cupping therapy may be considered where muscular tension, regional discomfort or selected musculoskeletal symptoms form part of the clinical picture. Breuss massage may be considered for back discomfort and muscular tension. These approaches do not treat chronic pain mechanisms in general.

Baunscheidt therapy may be considered in selected patients with persistent or recurrent pain and musculoskeletal complaints as part of an individual treatment strategy.

The great majority of situations are not urgent. A few signs do call for prompt medical assessment:

In these situations contact your doctor, an emergency service or the emergency numbers rather than requesting a routine appointment.

Chronic pain is a broad framework. Depending on your symptoms, a more specific page may be more useful:

Back pain covers persistent lower back pain, disc-related symptoms and sciatica. Osteoarthritis covers persistent joint pain and stiffness. Tendinopathy covers persistent tendon-related symptoms. Musculoskeletal pain covers joint, muscle and movement-related symptoms more broadly. Neck pain covers persistent cervical symptoms.

Neuropathic pain covers nerve injury and nerve disease. Autoimmune and inflammatory conditions cover established or suspected inflammatory disease. Fatigue and brain fog sometimes accompany the pain picture. Sports injuries cover pain that persists after a sport-related injury or overload.

Two articles go deeper than this page can: why pain becomes chronic, which sets out the mechanisms, and chronic pain: what role can naturopathy play, which describes the integrative approach.

Centre Algos is based in Fribourg. The first consultation takes time to go through the history of your pain, its impact, what has already been tried and what still deserves clarification.

We then discuss together which options make sense in your situation and how they fit alongside your medical care.
