"When pain becomes a lifestyle" - fibromyalgia disorder

Between mystery and diagnosis

Fibromyalgia (or fibro) is a complex chronic disorder that affects millions of individuals globally. It is characterized by widespread pain in multiple areas of the body, in addition to chronic fatigue, sleep disturbances, cognitive dysfunction, and a range of other systemic symptoms. However, despite the prevalence of the syndrome, it remains shrouded in mystery, and its understanding and diagnosis are associated with a number of clinical challenges due to the absence of specific biological indicators and a clear understanding of its pathological mechanism. This reality often leads to delayed diagnosis or misdiagnosis by healthcare providers, which increases patient suffering and negatively affects the quality of their daily lives.

Global prevalence

This syndrome affects between 0.2% and 6.6% of the world's population and is more common in women over the age of fifty, where...

It was mentioned that the prevalence of fibromyalgia among the population ranges from 2% to 8% depending on the region and diagnostic criteria. It was also emphasized that women are more affected than men and that diagnosis may be incomplete in some groups.

But what Is fibromyalgia?

It is defined as a chronic and widespread pain syndrome where sufferers experience continuous pain throughout the body, often described as burning, throbbing, or similar to deep muscular pain. What distinguishes this pain is that it does not result from inflammation or direct tissue damage, but rather it is believed that the underlying cause lies in a dysfunction in how the central nervous system processes pain signals. In other words, the brains of those affected become more sensitive to sensory stimuli, even those that do not normally cause pain in healthy individuals, which is known as "Central Sensitization." However, fibromyalgia does not cause damage to muscle or joint tissues, but it significantly affects the patient's quality of life and daily functions.

Common symptoms of fibromyalgia

Its symptoms are not limited to pain only but include a wide range of physical, neurological, and psychological problems that negatively affect the quality of life of those affected, where...

Widespread pain: The most common and distinctive symptom, often described as a constant dull ache lasting for more than three months, spreading to both sides of the body (right and left) and above and below the waist. It is described as burning, pressing, or throbbing pain.
Extreme fatigue: Patients feel chronic fatigue that does not go away even after long periods of rest or sleep, and many wake up feeling exhausted and unrested, which affects their ability to perform daily tasks.
Sleep disturbances: Difficulty falling asleep or staying asleep, in addition to accompanying disorders such as Restless Legs Syndrome and sleep apnea.
"Fibro fog" (Cognitive Difficulties): Also known as "Brain Fog," it includes difficulty concentrating, short-term memory impairment, a lack of attention, and slowness in thinking and mental processing.
Hypersensitivity to stimuli: Many patients suffer from an excessive response to light touch, loud noises, and bright lights.
Comorbid conditions: It is often associated with other health problems and disorders, including Irritable Bowel Syndrome (IBS), Chronic Fatigue Syndrome, migraine headaches, Interstitial Cystitis or Painful Bladder Syndrome, Temporomandibular Joint (TMJ) disorder, and Postural Orthostatic Tachycardia Syndrome (POTS).

Causes of fibromyalgia

It is one of the complex chronic conditions whose exact causes are not yet fully understood. Although the direct cause is unknown, experts suggest that it results from the interaction of several factors, such as...

Genetic factors: Research indicates that inherited genes from parents may play a role in increasing the risk of developing it. It is believed that certain genetic mutations affect the formation of neurotransmitters in the brain, which transmit pain signals between the brain and the body.
Dysfunction in processing pain signals: Researchers suggest that this is due to a dysfunction in how the brain receives nerve signals, where normal pain signals are amplified in the central nervous system, leading to a more intense sensation of pain even with non-painful stimuli.
Neurochemical imbalance: Fibromyalgia is associated with a disturbance in the balance of chemical neurotransmitters in the brain, such as serotonin (mood and sleep regulation), dopamine (motivation and pleasure), and norepinephrine (stress and pain response).
Physical or Psychological Trauma: It may appear after a severe physical injury (such as a car accident or a neck or back injury), a severe infection, and acute psychological stress.
Sleep Disturbances: Unrestful or fragmented sleep weakens the body's ability to recover and increases the nervous system's sensitivity to pain.
Infections: Certain illnesses may lead to fibromyalgia or exacerbate its symptoms.

Risk factors for developing fibromyalgia

Although the direct cause of this condition remains unknown, research has identified a set of risk factors that are associated with an increased likelihood of developing it, namely:

Genetic factors play a fundamental role, as it has been found that individuals who have first-degree relatives with fibromyalgia are more susceptible to developing it. Women are more susceptible than men, and this is likely related to hormonal and biological factors. In addition, middle age (30–50 years) represents the most common age group for diagnosis. Psychological disorders (such as depression, anxiety, and post-traumatic stress disorder) and continuous psychological stress play an important role in predisposing the body to fibromyalgia, especially when accompanied by sleep disturbances or physical or emotional stress. Furthermore, an association has been found between fibromyalgia and a previous severe viral or bacterial infection or suffering from chronic diseases such as rheumatoid arthritis, Irritable Bowel Syndrome, or Chronic Fatigue Syndrome. These factors show that fibromyalgia is not the result of a single cause but requires a comprehensive assessment of the individual's medical, psychological, and genetic history to determine the level of risk.

How to diagnose fibromyalgia

Due to the absence of specific laboratory or imaging tests, diagnosis relies mainly on clinical assessment and ruling out other diseases. According to the modern diagnostic criteria issued by the American College of Rheumatology (ACR) in 2010 and revised in 2016, diagnosis is based on three main axes:

The presence of widespread pain in four of five main areas of the body that lasts for at least three months.
An elevated symptom severity scale that includes fatigue, sleep disturbances, and cognitive difficulties.
The absence of other diseases that explain the symptoms, which is confirmed through laboratory tests such as: Complete Blood Count (CBC), Thyroid Stimulating Hormone tests (TSH), Erythrocyte Sedimentation Rate (ESR), autoimmune disease tests (ANA, RF), and Vitamin D and B12 analysis.

Methods of treating fibromyalgia

There is no definitive cure for it yet, but a combination of treatment options is used to control symptoms and improve quality of life. Following a multidisciplinary treatment approach is the most appropriate according to modern guidelines, where:

Drug therapy: This includes medications approved for serotonin and norepinephrine reuptake inhibitors, such as Duloxetine and Milnacipran, which are effective in relieving pain and improving mood. Also, anticonvulsant drugs like Pregabalin and Gabapentin are used to reduce nerve hyperexcitability. Tricyclic antidepressants like Amitriptyline help improve sleep.
Non-drug therapies: Regular, low-intensity aerobic exercises (such as walking and swimming) are one of the best ways to improve symptoms. Cognitive Behavioral Therapy (CBT) helps patients manage pain and anxiety associated with the disease. Also, relaxation techniques (such as yoga and tai chi) and physical therapy have proven effective in reducing stress and muscle stiffness.
Psychological and social support: Family support, participation in support groups, and specialized psychological follow-up are essential supporting elements for psychological and social adaptation to the disease.

Aquatic therapy as a treatment option

In recent years, aquatic therapy has emerged as an effective and safe means of improving fibromyalgia symptoms. Water provides a low-impact environment that helps reduce pressure on joints and muscles and facilitates the performance of movements that may be painful on land. The warm temperature of the water also contributes to muscle relaxation and stimulates blood circulation. A clinical study conducted on fibromyalgia patients showed that aquatic exercises significantly helped reduce pain and improve physical fitness and sleep quality. In a randomized controlled trial, Assis et al. (2006) found that deep water running led to significant clinical improvements and contributed to relieving physical symptoms and improving functional performance, indicating the effectiveness of this type of therapy as part of a comprehensive treatment program.

Diet for fibromyalgia patients

Anti-inflammatory diet: Follow an anti-inflammatory diet, such as the Mediterranean diet, which is rich in vegetables, fruits, whole grains, olive oil, and fish, as it reduces fatigue, pain, and chronic inflammation.
Vegetarian/vegan diet: Rely on a vegetarian or vegan diet, as it reduces the level of C-reactive protein (CRP) and inflammation indicators, and improves weight, cholesterol, and general symptoms.
Increased antioxidants: Increase antioxidants such as: CoQ10, vitamins A, C, and D, turmeric, ginger, and green tea, as they relieve oxidative stress associated with pain.
Gluten-free diet: Following a gluten-free diet is beneficial, especially for those with non-celiac gluten sensitivity (NCGS), and it improves pain, fatigue, and the number of painful points.
Low-FODMAP diet: Limiting short-chain carbohydrates (Low-FODMAP) improves digestive symptoms and pain in associated irritable bowel syndrome (IBS) cases.
Important supplements: Magnesium: improves pain and muscle strength; Coenzyme Q10: reduces pain and stress; and Vitamin D: is associated with improved pain, especially in those with a deficiency.

Lifestyle for fibromyalgia patients

Low-intensity aerobic exercise: (such as walking and swimming) reduces pain, stress, and improves sleep quality.
Cognitive behavioral therapy (CBT): helps modify negative thinking and improve adaptation to pain.
Improve sleep quality: as fragmented sleep exacerbates symptoms. Therefore, improving sleep reduces pain and fatigue.
Weight loss in cases of obesity: reduces the body mass index (BMI), which reduces the level of inflammation and pain sensitivity.
Acupuncture: stimulates the secretion of natural painkillers and relieves chronic pain.
Low-level laser therapy (LLLT): improves pain, fatigue, depression, and the number of painful points.

Impact of different types of exercises on adults with fibromyalgia

Aerobic exercise: Improves health-related quality of life and reduces indicators of pain, stiffness, and fatigue, although its effects on fatigue are of limited quality. It works best when practiced two to three times a week for 30–60 minutes at a low to moderate intensity (50–80% of maximum heart rate) and is considered a safe and acceptable option.
Resistance training: Reduces pain, the number of painful points, and improves physical performance, with a moderate effect on psychological state. For example, 16–21 weeks of adaptive resistance led to a significant improvement in FIQ, physical strength, and pain compared to control, and moderate training intensity (40–85% of 1RM) is effective and enhances functional ability.
Stretching: Reduces pain and improves quality of life, but it has not shown a tangible effect on depression. When compared to resistance or aerobic groups, its benefit is less in reducing pain and improving physical performance.

Conclusion

Fibromyalgia represents more than just a musculoskeletal disorder; it is a complex reflection of deep neurological and biochemical imbalances that affect the way the brain processes pain and stress. Although there are no specific biomarkers or a definitive cure yet, progress in understanding the neurophysiology of this disorder has paved the way for a multidisciplinary treatment approach that focuses on awareness, psychological support, physical rehabilitation, and targeted pharmacological intervention.
