Fibromyalgia is a chronic disorder that causes pain and tenderness throughout the body. It is characterised by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive issues. While the exact cause of fibromyalgia is unknown, researchers believe it involves changes in the way the brain and spinal cord process painful and non-painful signals, leading to increased sensitivity to pain. Although fibromyalgia itself does not typically cause inflammation, people with fibromyalgia often experience other inflammatory conditions, such as rheumatoid arthritis or autoimmune disorders. Additionally, a 2021 study suggested a potential link between autoantibodies and fibromyalgia symptoms, including reduced muscular strength and increased sensitivity to pain.

What You'll Learn
Fibromyalgia is not an inflammatory autoimmune disorder
Fibromyalgia is a chronic condition that causes widespread pain and tenderness in the body. It is characterised by fatigue, sleep issues, cognitive problems, and heightened sensitivity to pain. While the exact cause of fibromyalgia is unknown, it is believed to involve the nervous system's altered processing of pain signals in the brain and spinal cord.
Fibromyalgia is not considered an inflammatory autoimmune disorder. Traditionally, it has not been associated with inflammation, a hallmark of autoimmune diseases. However, recent studies have suggested a potential link between fibromyalgia and inflammation. For instance, a 2021 study found that autoantibodies, which are associated with autoimmune conditions, may contribute to fibromyalgia symptoms. Additionally, research has indicated a connection between fibromyalgia and the inflammatory autoimmune disease Sjögren's disease.
While fibromyalgia itself is not classified as an autoimmune disorder, it often co-occurs with other chronic inflammatory or autoimmune disorders. These can include rheumatoid arthritis, lupus, and irritable bowel syndrome. The presence of these comorbid conditions can exacerbate fibromyalgia symptoms and further complicate diagnosis and treatment.
The treatment for fibromyalgia focuses on managing symptoms and improving quality of life. This includes medications, self-care strategies, and lifestyle changes such as exercise, stress reduction techniques, and a balanced diet. It's important to note that fibromyalgia is not considered dangerous or life-threatening, but its persistent symptoms can significantly impact a person's daily life.
Healthcare professionals often employ a combination of treatments to address fibromyalgia. Non-pharmacological approaches include physical therapy, stretching, and exercises to improve muscle and joint health. Psychological treatments play a crucial role in maintaining a healthy self-image and managing mental and emotional symptoms. Pharmacological treatments are also utilised to alleviate specific symptoms.

It causes musculoskeletal pain
Fibromyalgia is a chronic disorder characterised by widespread pain in the body. It causes musculoskeletal pain, or pain in the muscles and bones. It is not an autoimmune disorder, and traditionally, it is not thought to cause inflammation. However, a 2021 study found that autoantibodies may contribute to fibromyalgia, as mice injected with autoantibodies from people with fibromyalgia experienced reduced muscular strength and greater sensitivity to painful sensations.
People with fibromyalgia experience heightened sensitivity to pain. This is due to the way the brain and spinal cord process painful and non-painful signals, increasing overall sensitivity to pain. This heightened sensitivity means that even a gentle touch can be painful. The pain can be described as a deep, burning, or throbbing ache that has lasted for at least three months. It is considered widespread when it occurs on both sides of the body and above and below the waist.
The pain can be felt in the muscles and soft tissues of the legs, with the legs feeling similar to the stiffness of arthritis or the soreness of a pulled muscle. It is also common to feel pain in the back, with the neck and back feeling particularly painful. The pain can be so disruptive that it affects sleep, with many people experiencing sleep disorders such as restless legs syndrome and sleep apnea.
Fibromyalgia is more common in women than in men, and it usually occurs in young or middle-aged women. It tends to run in families, so genetic factors are likely to contribute to the disorder. However, it can also occur in people with no family history of the disorder. Researchers believe that environmental triggers, such as having a disease that causes pain or experiencing physical or emotional trauma, may also play a role in the development of fibromyalgia.

It is often genetic
Fibromyalgia is a chronic disorder characterised by widespread pain and tenderness in the body. It is also associated with fatigue, sleep issues, cognitive dysfunction, and mood disorders. While the exact cause of fibromyalgia is not fully understood, there is evidence suggesting that it often has a genetic component and tends to run in families.
Genetic factors are believed to play a significant role in the development of fibromyalgia. Studies have shown that genetic variants and inheritance patterns in pain-related genes can contribute to increased pain sensitivity and the development of chronic pain conditions, including fibromyalgia. Researchers have identified hundreds of pain-regulated genes that may be involved in pain sensitivity and analgesia, such as genes encoding for voltage-gated sodium channels and catechol-O-methyltransferase.
The risk of developing fibromyalgia is significantly higher for first-degree relatives of affected individuals. Genome-wide association studies have implicated specific genes in the pathogenesis of fibromyalgia, including SLC64A4, TRPV2, MYT1L, and NRXN3. These genes may influence the production and breakdown of neurotransmitters, which are chemical messengers in the brain that play a crucial role in pain signalling.
Additionally, epigenetic alterations, such as DNA methylation patterns, have been observed in people with fibromyalgia. These alterations can affect gene expression and may be influenced by environmental factors, further supporting the idea that both genetic and environmental factors interact to determine an individual's risk for developing fibromyalgia. However, it is important to note that fibromyalgia does not always follow a clear pattern of inheritance, and some people with the condition have no family history of it.
While genetics may increase the likelihood of developing fibromyalgia, it is not the sole determinant. Environmental and nongenetic factors also play a critical role. These factors include physical injuries, infections, psychological stress, social factors such as childhood trauma, and physical inactivity. The interaction between these environmental triggers and an individual's genetic makeup likely contributes to the development of fibromyalgia.

It is more common in women
Fibromyalgia is a poorly understood, chronic pain syndrome that causes tenderness and widespread pain in the body. It is more common in women, with estimates suggesting that it is about 7 times more prevalent in women than in men. The condition is most prevalent among middle-aged women, comprising 75%–90% of those diagnosed.
There are several factors that may contribute to the higher prevalence of fibromyalgia among women. One reason could be the presence of more "tender points" in women compared to men. Tender points refer to areas of tenderness around the joints, and women tend to report more of these points and experience more intense pain at these sites. However, recent revisions in diagnostic criteria have eliminated the exclusive reliance on tender points, leading to a reduction in the apparent gender disparity.
Hormonal changes and stress related to menstruation, menopause, or pregnancy may also play a role in the higher incidence of fibromyalgia among women. Women are reported to have a more severe stress response than men, and chronic stress can negatively impact the immune system's ability to fight diseases. Additionally, women with fibromyalgia might experience complications with premenstrual syndrome and more severe lower abdomen and back pain.
Another factor could be the higher prevalence of concomitant psychiatric disorders in women compared to men. Conditions such as bipolar disorder, anxiety disorders, personality disorders, and major depression are more frequently observed in women with fibromyalgia. These psychiatric comorbidities can further complicate the condition and impact a woman's overall well-being.
While the exact causes are still being investigated, it is clear that fibromyalgia disproportionately affects women. Researchers are working to better understand the interplay of genetic, environmental, and physiological factors that contribute to this gender disparity in the prevalence of fibromyalgia.

It can be treated with muscle relaxants and anti-inflammatory drugs
Fibromyalgia is a chronic disorder characterised by persistent, widespread pain, sleep problems, and fatigue. It is a long-term condition that affects the brain's processing of painful and non-painful signals, increasing overall sensitivity to pain. While there is no cure for fibromyalgia, medicines and treatments can help control the symptoms.
Muscle relaxants are often prescribed to help reduce tenderness and relax patients, easing their anxiety. These include tizanidine, baclofen, metaxalone, cyclobenzaprine, clonazepam, and alprazolam. Cyclobenzaprine is a tricyclic antidepressant that acts on both alpha and gamma neurons in the central nervous system, reducing muscle stiffness and enhancing sleep quality. Tizanidine is another muscle relaxant that targets alpha-2 receptors in the brain and spinal cord, reducing the release of the pain-signalling chemical "substance P". It is often taken at bedtime to decrease muscle stiffness and improve sleep.
However, it is important to note that muscle relaxants can have side effects, such as sedation, weight gain, fatigue, dry mouth, constipation, and a grogginess. Additionally, the long-term efficacy of these drugs for fibromyalgia has not been fully established. Patients are advised to consult their doctors before taking muscle relaxants to ensure safe and effective use, especially when taking other medications.
In addition to muscle relaxants, anti-inflammatory drugs are also used to treat fibromyalgia. Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat pain associated with fibromyalgia. NSAIDs have analgesic (pain-killing), antipyretic (fever-reducing), and anti-inflammatory effects at higher doses. While some people find relief from NSAIDs, evidence suggests that they may not be effective for everyone with moderate or severe fibromyalgia pain.
Other treatments for fibromyalgia include self-care, physical activity, cognitive-behavioural therapy, and medications such as duloxetine (Cymbalta), milnacipran (Savella), pregabalin (Lyrica), and gabapentinoids like gabapentin and pregabalin. These drugs work to turn down the "pain volume" in the central nervous system, reduce fatigue, improve mood, and promote sleep.
