Difference Between Fibromyalgia and MS

What is Fibromyalgia?

Fibromyalgia is a rheumatic disease. Typically, it occurs at the age of 25 to 60 years. It occurs more often in women than in men.

The symptoms of fibromyalgia are:

  • Increasing pain or sensitivity at certain points of the body,
  • Unreasonable and uncontrollable feeling of fatigue,
  • Depression and anxiety.

The muscles feel as if they are overwhelmed by heavy physical activity without a clear reason. Sometimes the muscles are tense, “burning”, or painful. Pain in fibromyalgia is very specific – it is felt throughout the body, both in the left and right half, under and over the waist, in the middle or low in the back, chest, and neck. Specific points on the body are affected, at the pressure of which the patient experiences severe pain.

Other symptoms of fibromyalgia are:

  • Sleep problems,
  • Dry mouth, nose, and eyes,
  • Strong sensitivity to cold or hot,
  • Inability to concentrate,
  • Urinary incontinence,
  • Irritated bowel,
  • Numbness or tingling of the fingers,
  • Stiffness.

It is believed that the pathogenesis of the disease is related to an excessive accumulation of certain chemicals – neurotransmitters, in the brain. As a result, there are processes in the nervous system that lead to an increase in the sense of pain.

Studies have shown the extremely low levels of hormones – serotonin, noradrenaline, and dopamine. This explains the occurrence of disorders in sleep, appetite, mood, and the reactions of the patients in stressful situations.

The risk factors associated with unlocking this disease are:

  • Strong stressful situation;
  • Physical trauma;
  • Surgical intervention;
  • Genetic factors.

Diagnosis of fibromyalgia is based on the patient’s history and examination. Practice shows that often the disease remains unrecognizable.

In order to exclude the possibility of another illness, a number of studies have to be made – complete blood test, blood sugar, thyroid hormones, etc. It has to be considered the fact that the symptoms of fibromyalgia persist for at least three months.

There is no specific treatment. A good influence on pain, feeling of fatigue, and on the improvement of cognitive function has the use of analgesic agents from the group of non-steroidal anti-inflammatory and opioid analgesics as well as treatment with antidepressants and antiepileptics. To control stress, it is also appropriate to conduct cognitive-behavioral therapy.

What is MS?

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease. Symptoms usually occur between the ages of 20 and 40 years. Women develop multiple sclerosis more often than men.

Symptoms of multiple sclerosis vary considerably between patients, and at different periods in the same person. They include:

  • Sensory disorders – hypoaesthesia, pain, paraesthesia,
  • Feeling of passing of electricity along the back – the so-called a symptom of lhermitte,
  • Feeling cold or warming of limbs,
  • Visual disturbances,
  • Motor disorders – stiffness, weakness, loss of muscle strength, onset of pathological reflexes,
  • Development of pareses,
  • Changes in muscle tone,
  • Coordination disorders – gait changes, dissymmetry, chanted speech, tremor,
  • Sexual problems,
  • •Problems with bowel and bladder function,
  • Acute or chronic pain,
  • Fatigue.

The MS is characterized by demyelination plaques, scattered in the white matter of the brain and spinal cord. In MS, within a faulty immune system response, tissue belonging to the body is recognized as a foreign one and attacked as such. An inflammation reaction that leads to myelin injury develops. Inflammation damages myelin and oligodendrocytes – cells in the central nervous system responsible for the production and maintenance of the myelin coverage of the axons.

The demyelinated axons cannot effectively carry out nerve impulses. The performance of nerve impulses is delayed and sometimes even blocked. Thus, MS affects the ability of the brain to control functions such as vision, walking, talking, etc.

It is not known what causes multiple sclerosis. It is believed that a combination of multiple factors is responsible for the development of the disease. The role of a number of factors has been discussed, such as:

  • Viruses,
  • Environmental factors,
  • Hereditary factors,
  • Autoimmune disease.

The process of diagnosing MS begins with the exclusion of other possible diseases. No single test alone is a conclusive evidence of MS. Therefore, the diagnosis should be a combination of history, neurological status, and test results.

Tests needed to diagnose are:

  • Magnetic resonance imaging,
  • Evoked (induced) potentials,
  • Lumbar puncture.

There is no medication to treat MS. However, a number of medications have been developed that affect the symptoms of multiple sclerosis or alter the severity and frequency of seizures. These are:

  • Corticosteroids,
  • Immunomodulators,
  • Immunosuppressants.

Difference Between Fibromyalgia and MS

  1. Definition 

Fibromyalgia: Fibromyalgia is a chronic rheumatic condition, causing pain in certain body parts.

MS: Multiple sclerosis is a chronic degenerative disease of the central nervous system.

  1. Occurrence

Fibromyalgia: Fibromyalgia typically occurs at the age of 25 to 60 years.

MS: Multiple sclerosis typically occurs at the age of 20 to 40 years.

  1. Symptoms

Fibromyalgia: The main symptoms of fibromyalgia are increasing pain or sensitivity at certain points of the body, unreasonable and uncontrollable feeling of fatigue, depression, anxiety, etc.

MS: The symptoms of Multiple sclerosis include sensory disorders, symptom of lhermitte, visual disturbances, motor disorders, pareses, changes in muscle tone and coordination, acute or chronic pain, fatigue, etc.

  1. Pathogenesis

Fibromyalgia: The pathogenesis of the fibromyalgia is related to an excessive accumulation of neurotransmitters in the brain. This leads to an increase in the sense of pain.

MS: In Multiple sclerosis, within a faulty immune system response, tissue belonging to the body is recognized as a foreign one and attacked as such. An inflammation reaction that leads to myelin injury develops.

  1. Risk factors

Fibromyalgia:  The risk factors associated with unlocking the fibromyalgia are a strong stressful situation, physical trauma, surgical intervention, genetic predisposition.

MS: A combination of multiple factors is responsible for the development of Multiple sclerosis, such as environmental factors, hereditary factors, autoimmune disease.

  1. Diagnosis

Fibromyalgia: Diagnosis of fibromyalgia is based on the patient’s history and examination. In order to exclude the possibility of another illness, a number of studies have to be made – complete blood tests, blood sugar, thyroid hormones, etc.

MS: No single test alone is a conclusive evidence of Multiple sclerosis. Tests needed to diagnose are magnetic resonance imaging, evoked (induced) potentials, lumbar puncture.

  1. Treatment

Fibromyalgia: There is no specific treatment for fibromyalgia. A good influence on pain, fatigue and cognitive function has the use of non-steroidal, anti-inflammatory, and opioid analgesics as well as treatment with antidepressants and antiepileptics. To control stress, it is also necessary to conduct cognitive-behavioral therapy.

MS: A number of medications affect the symptoms of MS or alter the severity and frequency of seizures. These are corticosteroids, immunomodulators, and immunosuppressants.
