Fibromyalgia Syndrome

Fibromyalgia syndrome usually consists of widespread muscle pain, fatigue, and multiple tender points on the body. While there is no specific, identifiable cause of fibromyalgia syndrome, certain factors -- such as being female or having a family history of the condition -- put you at a higher risk of developing it. Fibromyalgia syndrome is often considered an arthritis-related condition. But because it does not cause inflammation or damage to the joints, muscles, or other tissues, it is not truly a form of arthritis.

 

Fibromyalgia Syndrome Defined

Fibromyalgia syndrome (also known as FMS or just fibromyalgia) is a syndrome, rather than a disease. Unlike a disease, which is a medical condition with a specific cause or causes and recognizable signs and symptoms, a syndrome is a collection of signs, symptoms, and medical problems that tend to occur together but are not related to a specific, identifiable cause.
 
Fibromyalgia syndrome is a common and chronic disorder characterized by widespread muscle pain, fatigue, and multiple tender points. The word fibromyalgia comes from the Latin term for fibrous tissue (fibro) and the Greek terms for muscle (myo) and pain (algia). Tender points are specific places on the body -- on the neck, shoulders, back, hips, and upper and lower extremities -- where people with fibromyalgia syndrome feel pain in response to slight pressure.
 

Is Fibromyalgia Arthritis?

Although fibromyalgia syndrome is often considered an arthritis-related condition, it is not truly a form of arthritis (a disease of the joints) because it does not cause inflammation or damage to the joints, muscles, or other tissues. However, like arthritis, fibromyalgia syndrome can cause significant pain and fatigue, and it can interfere with a person's ability to carry out daily activities. Also, like arthritis, fibromyalgia is considered a rheumatic condition.
 
You may wonder what exactly rheumatic means. Even healthcare providers do not always agree on whether a disease is considered rheumatic. If you look up the word in the dictionary, you'll find it comes from the Greek word rheum, which means flux -- not an explanation that gives you a better understanding. In medicine, however, the term rheumatic means a medical condition that impairs the joints and/or soft tissues and causes chronic pain.
 

Fibromyalgia Syndrome Frequency

FMS affects 3 million to 6 million people, or as many as 1 in every 50 Americans. For unknown reasons, between 80 percent and 90 percent of those diagnosed with fibromyalgia are women; however, men and children also can be affected. Most people are diagnosed with fibromyalgia syndrome during middle age, though the symptoms often become present earlier in life.
 
People with certain rheumatic diseases, such as rheumatoid arthritis, systemic lupus erythematosus (commonly called lupus), or ankylosing spondylitis (spinal arthritis) may be more likely to have fibromyalgia syndrome as well.
 
Several studies indicate that women who have a family member with FMS are more likely to have fibromyalgia themselves, but the exact reason for this is unknown. Fibromyalgia syndrome could have a hereditary component (having to do with a certain gene or genes that family members have in common) or it could be linked to factors in the environment.
