Fibromyalgia vs. MS: The Differences And Similarities

Could the constant pain or fatigue you’re experiencing be more than just passing stress or exhaustion? Chronic conditions like fibromyalgia and MS are becoming increasingly prevalent worldwide, affecting millions of people. Despite their considerable effect on everyday life, these conditions often remain underdiagnosed. Fibromyalgia, for instance, is estimated to affect up to 5% of the global population. At the same time, over 2.8 million people today live with MS. What makes these two conditions so prevalent yet so difficult to diagnose? As gaps in prevalence estimates persist, it’s crucial to explore the underlying causes and latest findings about fibromyalgia and MS.

Fibromyalgia vs. MS – An Overview

Fibromyalgia is a long-term health issue that leads to widespread pain across the body.

While the cause remains unknown, many experts believe it may involve abnormal processing of pain signals within the brain and spinal cord.

Due to its persistent nature, this condition often affects musculoskeletal areas and can make daily tasks challenging.

Multiple sclerosis (MS) is a chronic autoimmune disorder that causes inflammation and harm to the central nervous system (spinal cord).

In this condition, the immune system abnormally attacks the myelin sheath, which protects nerve fibers. This damage interferes with communication between the brain and body, resulting in various symptoms.

MS often develops in young adults, specifically those aged 20 to 40, and can significantly disrupt routine activities.

Fibromyalgia vs. MS – Symptoms

Both conditions can present with similar symptoms, such as fatigue and cognitive difficulties, but each condition has some unique characteristics.

Fibromyalgia symptoms include:

Persistent fatigue
Cognitive difficulties, often known as “fibro fog”
Stiff and tender points in muscles or tendons
Sleep disturbances, leading to restlessness or insomnia
Heightened sensitivity to pain
Headaches and nerve pain
Digestive problems like irritable bowel syndrome (IBS)

MS symptoms include:

Muscle weakness and stiffness
Vision difficulties like blurriness, double vision, or loss of sight
A tingling or numbness in different body parts
Bladder and bowel control problems
Balance and coordination difficulties
Speech changes due to slower nerve signal transmission

Fibromyalgia Pain – How Does It Feel?

People with fibromyalgia often report a constant ache spread across multiple regions of the body.

This pain can cause muscles to feel sore or strained, even without physical activity. It may range from a light ache to intense, burning, or sharp sensations.

Common experiences include:

Tender points that hurt even with medication
Muscle twitching or burning sensations
Deep, stabbing pain in muscles
Achiness around the neck, shoulders, back, and hips
Increased skin sensitivity in certain areas

The pain typically lasts long, making sleeping or staying active harder.

MS Pain – How Does It Feel?

MS pain can appear in various ways due to nerve damage, triggering sensations without a known cause. People with MS may experience:

Tingling and numbness in different parts of the body
Stabbing pain in areas like the face or jaw
A squeezing sensation around the torso, commonly referred to as the ‘MS hug’
A sharp, electric shock-like feeling, known as Lhermitte’s sign
Tightness or cramping in the muscles of the limbs

The intensity of pain varies.

Depending on the progression of MS, some individuals may experience mild tingling, while others face more severe discomfort.

Fibromyalgia vs. MS – Causes

Multiple causes may contribute to the occurrence of both fibromyalgia and MS.

Internal And External Causes

Fibromyalgia

Internal causes:

Genetics: Having a family history of fibromyalgia can increase the risk.
Neurochemical imbalances: Changes in brain chemicals like serotonin and norepinephrine may contribute to the condition.
Central sensitization: The nervous system becomes overly sensitive, making pain feel more intense.

External causes:

Physical trauma: Injuries or infections may trigger fibromyalgia in some people.
Emotional stress: Psychological stress, anxiety, or depression can make symptoms worse.
Environmental factors: Exposure to certain chemicals, like organophosphate pesticides and solvents, might increase risk.

MS

Internal causes:

Genetics: A family history of MS increases the risk.
Autoimmune factors: The immune system mistakenly attacks the protective layer (myelin) around nerve fibers.
Hormonal changes: Hormonal factors, particularly in women, may influence the risk of MS, as the condition is more prevalent in females, suggesting a potential link with estrogen levels.

External causes:

Vitamin D deficiency: Decreased vitamin D levels are connected to increased MS risk.
Smoking: Smoking is recognized as a significant risk factor for MS.
Climate influence: Areas with rising temperatures and sudden weather changes can impact the prevalence of MS.
Viral associations: Certain research suggests that infections with microbes, like the Epstein-Barr virus (EBV) and human herpesvirus-6 (HHV-6), may trigger MS in more vulnerable people.

Fibromyalgia vs. MS – Diagnosis And Treatment

The diagnosis and treatment of fibromyalgia and MS differ in several ways, although both conditions rely heavily on symptom evaluation.

Diagnosis

MS diagnosis typically involves ruling out other conditions through various tests. Doctors often perform an MRI and may also order:

Blood tests
Spinal tap
Evoked potential tests (to check nerve response)

Neurologists who specialize in the nervous system usually diagnose and treat MS.

On the other hand, a fibromyalgia diagnosis is made after the patient experiences widespread pain for more than three months without any identifiable cause.

Rheumatologists or primary care doctors typically manage fibromyalgia cases.

Treatment

For MS, doctors recommend medications to manage symptoms, slow the disease, and aid recovery from flare-ups. Treatment options include:

Steroids
Muscle relaxants
Fatigue management drugs
Antidepressants
Pain relievers
Medication for insomnia, sexual dysfunction, and bladder or bowel issues

In fibromyalgia, treatment focuses on symptom management. Doctors may prescribe specific medications approved for the condition, such as:

Antidepressants
Anti-seizure drugs
Pain relievers

Both conditions require personalized treatment plans, as medication responses can vary from person to person.

Fibromyalgia vs MS – Are There Any Similarities?

Fibromyalgia and MS share several similarities, particularly in their symptoms and risk factors.

Both conditions can cause fatigue, which causes individuals to feel tired often. Though they affect the body differently, there are notable overlaps in how they may develop.

Some key similarities include:

Similar age range: Both conditions commonly start between 20 and 40 years of age.
Genetic predisposition: Having a parent with MS or fibromyalgia increases the likelihood of developing either condition.
Autoimmune links: Both are associated with autoimmune conditions. Fibromyalgia is more prevalent in people with rheumatoid arthritis or lupus, while MS is linked to diseases like psoriasis, thyroid disease, and type 1 diabetes.
Role of infections: MS is linked to specific viral infections, and similar infections could contribute to fibromyalgia risk.

Frequently Asked Questions

Can MS Cause Itching?

Yes, MS can lead to itching. The condition affects the nerves and can result in dysesthesia, which includes abnormal sensations like itching.

This itching may come and go and occur in various body parts. In some individuals, itching may appear early in the disease, sometimes even before they receive a diagnosis.

Fibromyalgia vs. MS – Life Expectancies

While both of these are chronic conditions, their impacts on life expectancy differ.

Fibromyalgia symptoms are persistent but not life-threatening, and the condition does not shorten lifespan.

In contrast, MS can progress and lead to severe symptoms. As reported by the National Multiple Sclerosis Society, MS may reduce a person’s lifespan by about seven years, and severe forms can be life-threatening.

Despite this, the National Institute of Neurological Disorders and Stroke notes that many individuals with MS have a similar life expectancy to those without the disease.

Can An MRI Detect Fibromyalgia?

An MRI test cannot diagnose fibromyalgia, as it typically does not reveal specific signs of the condition.

However, some studies have noted unusual features in MRI scans of individuals with fibromyalgia compared to those without it.

These findings suggest that while MRIs can’t definitively detect fibromyalgia, they may show differences that could be relevant to understanding the condition.

Summary: Fibromyalgia vs. MS

Fibromyalgia and MS are chronic conditions that significantly affect daily life, comfort, and bodily functions.
While both share symptoms like fatigue and cognitive difficulties, they are distinct in their causes and treatment.
Fibromyalgia is a widespread pain disorder believed to result from abnormal pain processing in the brain and spinal cord. Treatment focuses on symptom relief and improving life quality.
Conversely, MS is an autoimmune disorder in which the body’s immune system abnormally targets the protective layer around nerve fibers. Treatment for MS aims to manage symptoms, slow progression, and assist recovery.
Even though these disorders are challenging, with accurate diagnosis and effective treatment, individuals can achieve a higher quality of life.
