PAIN & REHABILITATION

Fibromyalgia – A Complex Chronic Pain Syndrome

1. WHAT IS FIBROMYALGIA?

Fibromyalgia is a chronic pain condition characterized by widespread musculoskeletal pain, fatigue, sleep disturbance, cognitive difficulties, and increased sensitivity to sensory stimuli.

It is best understood as a disorder involving altered processing and amplification of pain signals within the nervous system. The pain is real, even though routine investigations may not show tissue damage or inflammation that explains the severity of symptoms.

Fibromyalgia can significantly affect physical function, sleep, work, mood, social activities, and overall quality of life.

2. EPIDEMIOLOGY

• Fibromyalgia affects approximately 2–4% of the population, although estimates vary between studies and diagnostic criteria.
• It is diagnosed more frequently in women than men.
• It can develop at different ages, including adulthood and, less commonly, childhood.
• Symptoms may begin gradually or follow a period of physical or psychological stress, illness, injury, or other health problems.
• Fibromyalgia may occur alongside other chronic conditions.

Commonly associated conditions include irritable bowel syndrome (IBS), migraine and other headaches, anxiety and depression, sleep disorders, temporomandibular disorders, chronic fatigue, and other chronic pain conditions.

3. HOW DOES FIBROMYALGIA DEVELOP?

The exact cause of fibromyalgia is not completely understood.

Current evidence suggests that several factors may interact, including altered pain processing, genetic susceptibility, physical or psychological stress, illness or injury, and sleep disruption.

The nervous system may become unusually sensitive to normally harmless or mildly painful stimuli. Pain signals may be amplified, while the body's normal pain-inhibiting mechanisms may be less effective.

4. COMMON SYMPTOMS

Symptoms vary considerably between individuals and may fluctuate over time.

• Widespread musculoskeletal pain
• Fatigue and low energy
• Unrefreshing sleep
• Morning stiffness
• Difficulty concentrating
• Memory difficulties or “fibro fog”
• Headaches or migraine
• Increased sensitivity to touch
• Sensitivity to sound, light, temperature, or odors
• Tingling or unusual sensory sensations
• Anxiety or depression
• Irritable bowel symptoms
• Reduced physical tolerance
• Difficulty maintaining normal daily activities

Symptoms may become more severe during a fibromyalgia flare.

5. UNDERSTANDING FIBROMYALGIA PAIN

Fibromyalgia pain does not necessarily feel the same every day. Different people may describe their pain differently, and the same person may experience several sensations.

Deep aching pain: A widespread, sore, aching sensation may feel similar to having very overworked muscles or having the flu. It commonly affects the neck, shoulders, back, hips, and legs.

Burning or tingling sensations: Some people describe burning, tingling, buzzing, pins-and-needles, or electric-like sensations. These symptoms should still be assessed clinically because similar sensations can occur with neurological conditions.

Sharp or stabbing pain: Brief episodes of sharp or stabbing pain can occur in different parts of the body.

Stiffness: The body may feel tight, stiff, or difficult to move, particularly after waking or after remaining in one position for a long time.

Tenderness and increased sensitivity: Normal pressure may feel unusually painful, such as tight clothing, a seatbelt, a gentle hug, or light pressure over sensitive areas.

Allodynia: Pain caused by a stimulus that would normally not be painful, such as light touch or clothing against the skin.

Hyperalgesia: An exaggerated response to a stimulus that is normally painful.

Flare pain: During a flare, pain may become more widespread or intense and may occur together with severe fatigue, poor sleep, brain fog, headache, and increased sensory sensitivity.

The location and intensity can change over time.

8. TENDER POINTS – HISTORICAL CONCEPT

Historically, fibromyalgia was associated with 18 specific tender points: occiput, low cervical region, trapezius, supraspinatus, second rib, lateral epicondyle, gluteal region, greater trochanter, and medial knee, with nine paired locations.

Important clinical update: Tender-point examination was central to older classification criteria. Modern diagnostic criteria do not require the presence of 11 out of 18 tender points. Therefore, tender points should not be used alone to diagnose or exclude fibromyalgia.

10. DIAGNOSIS

Fibromyalgia is primarily a clinical diagnosis.

The healthcare professional considers widespread pain, symptom duration, fatigue, sleep problems, cognitive symptoms, associated symptoms, functional limitations, medical history, and physical examination.

2016 ACR Classification Criteria:

• Widespread Pain Index (WPI) ≥7 and Symptom Severity (SS) scale score ≥5

OR

• WPI 4–6 and SS scale score ≥9

with symptoms present at a similar level for at least 3 months.

These criteria are useful for classification and clinical assessment, but diagnosis should always be made in the context of the individual's overall clinical presentation.

Depending on the presentation, clinicians may evaluate for conditions such as rheumatoid arthritis, systemic lupus erythematosus, hypothyroidism, vitamin deficiencies, neurological disorders, or other rheumatological and musculoskeletal conditions.

12. MANAGEMENT OF FIBROMYALGIA

There is no single treatment that works for everyone. Management is usually multidisciplinary and individualized.

Main goals:

• Reduce symptom severity
• Improve physical function
• Improve sleep
• Increase activity tolerance
• Improve confidence with movement
• Support participation in daily life
• Improve overall quality of life

13. NON-PHARMACOLOGICAL MANAGEMENT

Patient education and reassurance are important. Patients should understand that fibromyalgia pain is real, pain does not necessarily mean tissue damage is occurring, symptoms can fluctuate, exercise can be helpful when introduced gradually, and treatment focuses on improving function rather than eliminating every symptom.

Aerobic exercise: Regular low-to-moderate intensity activity can help improve physical function, exercise tolerance, fatigue, mood, and quality of life. Examples include walking, cycling, swimming, and aquatic exercise.

Strength training: May improve muscle strength, functional capacity, confidence with movement, and physical independence.

Flexibility and mobility: Gentle neck, shoulder, spinal, hip, and lower-limb mobility exercises may help people who experience stiffness.

Pacing: Pacing helps prevent the cycle of excessive activity followed by a flare and prolonged rest. The goal is manageable activity, recovery, and gradual progression rather than complete avoidance of activity.

Sleep management: Maintain a consistent sleep schedule, develop a relaxing bedtime routine, reduce stimulating activities before sleep, and address persistent sleep problems with a healthcare professional.

Stress management: Breathing exercises, mindfulness, meditation, yoga, relaxation techniques, structured routines, and psychological support may help.

CBT: Cognitive Behavioural Therapy may help with coping with chronic pain, stress, sleep, fear related to symptoms, and confidence. CBT does not mean that the pain is psychological; it is one tool for managing the impact of chronic pain.

14. FLARE MANAGEMENT

During a flare:

• Temporarily reduce exercise intensity rather than stopping all movement.
• Use gentle mobility exercises.
• Maintain normal daily movement as tolerated.
• Prioritize sleep and recovery.
• Use relaxation or breathing strategies.
• Gradually return to the usual activity level as symptoms settle.

A flare does not necessarily mean that tissue damage has occurred.

15. PHYSIOTHERAPY ROLE IN FIBROMYALGIA

Physiotherapy can play an important role in helping people become more physically active and functionally independent.

Assessment may include:

• Pain distribution and behaviour
• Functional limitations
• Strength and mobility
• Balance
• Exercise tolerance
• Posture and movement patterns
• Sleep and fatigue considerations
• Activity levels
• Fear or avoidance of movement

Physiotherapy management may include:

• Individualized graded exercise
• Aerobic conditioning
• Progressive resistance training
• Mobility exercises
• Functional training
• Pacing education
• Pain neuroscience education
• Relaxation techniques
• Home exercise programs
• Ergonomic advice
• Self-management strategies

16. EXERCISE PROGRESSION

Stage 1 – Establish tolerance: Start with short, manageable activity such as short walks, gentle mobility, low-intensity strengthening, and breathing exercises.

Stage 2 – Build consistency: Focus on performing activity regularly rather than exercising intensely.

Stage 3 – Gradual progression: Increase one variable at a time, such as duration, repetitions, resistance, or frequency.

Stage 4 – Functional integration: Progress toward meaningful activities such as household activities, work, walking outdoors, stairs, recreational activities, and community participation.

17. MANUAL THERAPY

Some people may experience short-term symptom relief from manual therapy. However, manual therapy should generally be considered an adjunct rather than the main treatment.

The long-term rehabilitation focus should remain on:

Education + Active Exercise + Self-Management + Functional Recovery

18. MEDICATION

Medication may be considered by a physician depending on the individual's symptoms and other health conditions.

Medications sometimes used in fibromyalgia management include:

• Duloxetine
• Milnacipran
• Pregabalin
• Amitriptyline

Medication selection should be individualized by a qualified healthcare professional.

Long-term opioid therapy is generally not recommended as a routine treatment for fibromyalgia because of limited benefit and potential risks.

19. COMMON MISCONCEPTIONS

“The pain isn't visible, so it isn't real.” FALSE. Fibromyalgia pain is real and can significantly affect physical and psychological functioning.

“Exercise will damage the muscles.” Not necessarily. Appropriately prescribed and gradually progressed exercise is an important component of fibromyalgia management.

“A normal scan means nothing is wrong.” Not necessarily. Fibromyalgia does not require visible structural damage on routine imaging.

“The person should simply rest.” Excessive inactivity can contribute to reduced physical capacity. The goal is usually appropriate movement and gradual activity progression, not complete rest.

20. KEY TAKE-HOME MESSAGE

Fibromyalgia may not be visible on an X-ray or MRI, but the person's symptoms are real.

Successful management usually involves:

Education + Gradual Exercise + Sleep Management + Stress Management + Self-Management + Appropriate Medical Care + Physiotherapy

Two people with fibromyalgia may have completely different symptoms and functional limitations. Even the same person may experience different symptoms from one day to another.

The goal is not always to eliminate every sensation of pain. The goal is to help the person move better, function better, manage symptoms confidently, and live a meaningful life.

LISTEN. VALIDATE. SUPPORT. EMPOWER.

You don't just treat fibromyalgia — you walk with the person through their rehabilitation journey.
