Have you ever heard a description of what it's like to have Fibromyalgia? Anyone who has come into contact with this disease knows how disabling it can be.

Immediately on waking up, pains break through the body heavy, persistent. With these, a feeling of extreme tirednessI find it difficult to complete tasks or concentrate on anything. In addition to these symptoms, which are already extremely disabling, at the end of the day, when it's time for restSleep doesn't come, or it's very superficial, agitated from moment to moment by the pain.

What do we know today about Fibromyalgia? What can we do, inside and outside the office, to alleviate the suffering brought on by this reality?

What is Fibromyalgia?

Fibromyalgia is a condition of chronic generalised pain which affects the muscles, tendons and ligaments. It goes far beyond physical pain: it is accompanied by intense fatigue, sleep disturbances, cognitive difficulties, and anxious and depressive symptoms.

Although it does not cause visible deformities or inflammation, severely impacts quality of lifeThis makes the most basic day-to-day tasks difficult.

Medical definition

According to World Health OrganisationFibromyalgia is classified as a generalised chronic pain syndrome. It is also an "idiopathic" disease - with no known cause. It is not an autoimmune or inflammatory disease, but it does involve the central nervous system, altering the perception of pain.

Recognition of status in Portugal

In Portugal, fibromyalgia is now officially recognised as a chronic condition, although many sufferers still face challenges in accessing appropriate diagnosis and treatment. Awareness is growing, but stigma persists.

Difference Between Fibromyalgia and Common Pain

To understand the difference between Common Pain and Fibromyalgia, it's important to realise what pain isand its purpose in the functioning of the human body.

Pain is a defence mechanism, embedded in the nervous systemThe nervous system's function is to alarm the brain into correcting something that is threatening the body's well-being - it's a reaction to a stimulus that the body considers negative or dangerous. The nervous system, through the nerves spread throughout the bodyIn this way, the brain is able to localise the focus of the pain, alerting the brain where the problem is so that it can be corrected. In addition, the brain registers different pain intensitiesindicating the urgency of stopping/ending the threat.

Pain is therefore a universal experience.

But fibromyalgia represents something very different from the common pain we all know.

À direita, a mesma figura com múltiplos pontos vermelhos espalhados pelo corpo inteiro, mostrando a dor difusa, generalizada, característica da fibromialgia.

A Common pain arises for a specific reason - an injury, inflammation or identifiable problem. It's a signal from the body that something needs attention. Generally, when the cause is treated, the pain disappears.

A Fibromyalgia It's like an alarm system that has become hypersensitive. An alarm that goes off all the time, with no apparent cause. The base level of pain is increased permanently, not temporarily, and even normal stimuli that wouldn't cause pain become painful, with the pain persisting even for no identifiable reason. In addition, the pain is not localised, reserved for one place - it is spread throughout the body. We call this pain "nociplastic pain".

Fibromyalgia it's not just "severe pain"This is a fundamental change at the root of the nervous system's pain perception mechanisms - in the way the nervous system perceives pain. process/receive sensations.

In other words, the brain interprets normal as well as dangerous signals, e natural and painful stimuliThis creates an experience of constant, generalised pain.

Here's a simple comparison:

Fibromyalgia's most common symptoms

Fibromyalgia manifests itself widely and varies from person to person, which can make it difficult to recognise clinically. However, there are striking symptoms shared by many patients:

  • Diffuse musculoskeletal painon both sides of the body

  • Intense fatigueeven after resting

  • Non-restorative sleep

  • Mental fog (difficulty concentrating and remembering)

  • Morning stiffness

  • Frequent headaches

  • Irritable bowel syndrome

  • Tingling in the hands or feet

  • Mood swings (anxiety, depression)

What are the causes and risk factors?

There is no single cause identified for the onset of fibromyalgia, but there are several factors that can contribute to it.

Genetics and family predisposition

There is evidence that the condition may have a hereditary inclinationand affects several members of the same family.

Physical or emotional stress

Events traumaticFibromyalgia, such as accidents or significant losses, can trigger the onset of fibromyalgia in predisposed people.

Traumas and infections

Infections viral or bacterial, as well as injuries severe physical illnesses are associated with some cases (e.g. Epstein-Barr virus)

The Diagnosis of Fibromyalgia

The diagnosis of fibromyalgia is clinicalnot based on laboratory tests.

One of the great difficulties faced by people with this condition is the feeling of mistrust which, unfortunately, still surrounds it, because it doesn't always present manifestations visible for those who witness it, or registrable in procedures such as medical examinations.

Fibromyalgia is diagnosed by exclusionoften after months or years of research.

Updated diagnostic criteria (ACR)

  • Chronic generalised pain for more than 3 months
  • Functional impact assessed with specific scales:
    • Widespread Pain Index (WPI)score that assesses the number of areas of the body where the patient has felt pain in recent weeks - at least 11 out of 19 points on the body assessed
    • Symptom Severity Scale (SS scale)score that assesses the severity of fatigue, non-restorative sleep, cognitive symptoms and other general symptoms
  • Exclusion of other conditions (e.g. arthritis, lupus, hypothyroidism)

The importance of early diagnosis

A timely diagnosis allows appropriate interventions to be initiated, preventing the patient's physical and psychological condition from worsening.

It is therefore important to look for specialised professionalsin order to minimise the impact of the condition as soon as possible.

Fibromyalgia and other pathologies

Here are some conditions that are often diagnosed with fibromyalgia:

  • Irritable bowel syndrome
  • Depression
  • Anxiety
  • Migraines
  • Chronic fatigue
  • Multiple chemical sensitivity

The presence of parallel pathologies requires a multidisciplinary approach to treatment.

Fibromyalgia in children and adolescents

Although less commonFibromyalgia can affect young people. Here are some of the frequent reports:

  • Persistent complaints of pain

  • Unexplained fatigue

  • Frequent absence from school

  • Sudden changes in behaviour

In these cases, early diagnosis and family support are crucial.

Fibromyalgia's impact on daily life

The limitations caused by fibromyalgia are real and often invisible:

  • Professional: absences from work, reduced productivity
  • Familylack of understanding, feelings of isolation
  • Personal / Spirituallow self-esteem, frustration, emotional distress
    • Fibromyalgia affects personal appearance, overall movement capacity, mobility...
    • Around 75% patients3 out of 4 develop depression or anxiety in their lifetime
  • Cognitive: mental confusion, loss of agility, memory

Special focus on women

Does fibromyalgia affect women more?

Studies indicate that around 80% of those diagnosed are women.

Gender differences in diagnosis

Women tend to report more pain and seek more medical support, which may influence the statistics.

Hormones and pain sensitivity

Female hormonal fluctuations, especially during periods such as the menopause, can intensify the symptoms.

How is Fibromyalgia treated?

Fibromyalgia is treatable through an approach of multidisciplinary - integrated between specialities - which combines different therapies. Here are some of the most commonly used:

Pharmacological treatment:

  • Antidepressants (duloxetine, milnacipran) to regulate neurotransmitters
  • Anticonvulsants (pregabalin, gabapentin) to modulate pain perception
  • Muscle relaxants in specific cases
  • Conventional painkillers - limited efficacy

Psychotherapy:

  • Cognitive Behavioural Therapy (CBT) for chronic pain management
  • Mindfulness and acceptance techniques
  • Group therapy to share experiences

Therapeutic exercise:

  • Gradual and adapted physical activity
  • Hydrotherapy and aquatic exercises
  • Relaxation and stretching techniques

Neurotherapy:

In NeuroPsyquewe used an integrated matching psychotherapy specialising in chronic pain with advanced neurotherapyIt is customised to the specific needs of each patient. On a case-by-case basis, physiotherapy can be a great help in treatment.

The role of psychotherapy in treatment

Psychotherapy plays an important central role in the treatment of fibromyalgia, helping patients to developing effective strategies for dealing with chronic pain.

Cognitive Behavioural Therapy (CBT):

  • Identifying and modifying thought patterns that amplify pain
  • Development of adaptive coping strategies
  • Management of stress and anxiety associated with the condition

Acceptance and Commitment Therapy (ACT):

  • Acceptance of the condition without resignation
  • Focus on personal values and quality of life
  • Reducing the internal struggle against pain

Pain education:

  • Understanding the mechanisms of chronic pain
  • Demystifying limiting beliefs
  • Empowerment through knowledge

A solid therapeutic relationshipbased on trust and proximityis fundamental to the success of the treatment.

Medicines used for treatment

Pain perception modulators:

  • Pregabalin: effective in reducing pain and improving sleep
  • Gabapentin: alternative to pregabalin with a similar profile

Antidepressants:

  • Duloxetine: acts on pain and associated depressive symptoms
  • Milnacipran: specific for fibromyalgia in some countries
  • Amitriptyline: can help with sleep and pain in low doses

Other medicines:

  • Cyclobenzaprine: muscle relaxant for stiffness
  • Tramadol: analgesic in selected cases

ImportantConventional anti-inflammatory drugs (ibuprofen, diclofenac) have limited efficacy in fibromyalgia, as there is no typical inflammation.

Pharmacological treatment should always be individualised and closely monitored by a specialised doctor.

When to seek professional help

Seek support when:

  • Pain interferes with work, social life or sleep
  • Constant feeling of "flu that won't go away"
  • Unrefreshing sleep even with many hours of sleep
  • Persistent physical and emotional exhaustion
  • Symptoms persist for more than 3 months
  • Quality of life is seriously compromised

  • Alternate demanding tasks with moments of rest
  • Learning to say "no" when necessary

Sleep hygiene:

  • Keeping regular bedtimes and getting up times
  • Create an environment conducive to rest
  • Avoid screens before bed
  • Relaxation techniques to help you fall asleep

Adapted physical activity:

  • Start gradually with low-impact exercises (ideally physiotherapy with specialised professionals)
  • Short walks, swimming or yoga
  • Listen to your body and adjust the intensity as necessary

Stress management:

  • Deep breathing techniques
  • Meditation or mindfulness
  • Pleasurable activities and relaxing hobbies

Food and Fibromyalgia

Diet can play an important role in managing symptoms.

Foods that relieve symptoms

A diet rich in fruit, vegetables, oily fish and whole grains can help reduce inflammation and improve general well-being.

Avoid inflammatory foods

Avoid inflammatories such as sugar, o gluten, o alcohol, a lactose, and the omega-6 present in highly processed vegetable oils.

Supplementation

Supplements such as magnesium, vitamin D-3 and omega-3 can be beneficial, always with medical advice.

Myths and Truths about Fibromyalgia

The mysticism associated with Fibromyalgia gives rise to misconceptions of what it's like to live with the condition, and it's essential spread knowledge to stimulate understanding. Here are some common myths:

Myth

Truth

"Fibromyalgia is just an excuse for people who are lazy"

Fibromyalgia is a serious condition - it's not a "way of being". This condition can bring a lot of suffering, especially if those around us don't know how to deal with it.

"Fibromyalgia is a psychological illness"

Fibromyalgia involves real changes in pain processing in the central nervous system. The psychological component can aggravate symptoms, but does not explain the origin of the condition.

"Fibromyalgia only affects women"

Although it is more prevalent in women, it can also affect men and children.
"Fibromyalgia has no treatment"Although there is no cure, there are effective treatments that help control symptoms and significantly improve quality of life.

Fibromyalgia - Rights and labour context

Fibromyalgia rights in Portugal

Although fibromyalgia is not explicitly listed in isolation in the National Table of Disabilities (TNI)This can be recognised as a disabling condition if its effects are proven to be limiting.

Recognition of disability equal to or greater than 60% gives access to:

  • Exemption from user charges
  • Priority in booking appointments
  • Tax benefits (e.g. IUC exemption, IRS reduction)
  • Social support as a dependency supplement

This degree is awarded for Social Security Medical Boardsby means of a medical report and functional assessment.

Sick leave and job protection

People with fibromyalgia are entitled to:

  • Medical leave (long-term illness) issued by the family doctor
  • Protection against dismissal due to illness (Article 351 of the Labour Code)
  • Possibility of job reassessment in the event of partial incapacity for work

In the event of prolonged sick leave, the employee can't be sacked, for this reason, without an opinion from the occupational doctor.

Workplace adaptation (Law no. 38/2004)

This law establishes the rights of people with disabilitiesincluding:

  • Adapting the workplace
  • Flexible working hours
  • Reduced working hours (when justified)
  • More frequent breaks for rest or pain relief
  • Reorganisation of tasks (avoid prolonged or repetitive physical effort)

These adaptations should be discussed with the labour doctor and appear in the Occupational Health and Safety Plan.

Advances in scientific research

Science continues to study ways to improve the diagnosis and treatment of fibromyalgia.

New treatments under study

Several clinical trials are exploring innovative therapies:

  • NeuromodulatorsDrugs that act on the neurotransmitter systems involved in chronic pain, such as serotonin, dopamine and glutamate. (study*) (study**)

  • Digital therapiesApplications and online platforms based on artificial intelligence and cognitive-behavioural therapy, which help patients manage symptoms such as pain, fatigue and insomnia. (study*) (study**)

  • Non-invasive brain stimulationTechniques such as Transcranial Magnetic Stimulation (TMS) (study*) (study**) and Transcranial Direct Current Stimulation (tDCS) (study*) (study**) show promising results in modulating pain and mood.

  • Medicinal cannabinoidsThe following have been studied for their potential to relieve pain, improve sleep and reduce anxiety, although the scientific evidence is still limited and controversial. (study*)

Future prospects

With more recognition, more investment is going into research into the condition. The next few years could bring good news for fibromyalgia sufferers.
