Fibromyalgia (pronounced fy-bro-my-AL-ja) is a common and complex chronic pain disorder that affects people physically, mentally and socially. 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, which has also been referred to as fibromyalgia syndrome, fibromyositis and fibrositis, is characterized by chronic widespread pain, multiple tender points, abnormal pain processing, sleep disturbances, fatigue and often psychological distress. For those with severe symptoms, fibromyalgia can be extremely debilitating and interfere with basic daily activities. 

Whether you have been diagnosed with fibromyalgia or suffer from its symptoms, or have a family member or friend with the disorder, this section is designed to provide you with a better understanding of this chronic pain disorder that affects millions of people worldwide.

Chronic widespread body pain is the primary symptom of fibromyalgia. Most people with fibromyalgia also experience moderate to extreme fatigue, sleep disturbances, sensitivity to touch, light, and sound, and cognitive difficulties. Many individuals also experience a number of other symptoms and overlapping conditions, such as irritable bowel syndrome, lupus and arthritis.

• Pain
  The pain of fibromyalgia is profound, chronic and widespread. It can migrate to all parts of the body and vary in intensity. FM pain has been described as stabbing and shooting pain and deep muscular aching, throbbing, and twitching. Neurological complaints such as numbness, tingling, and burning are often present and add to the discomfort of the patient. The severity of the pain and stiffness is often worse in the morning. Aggravating factors that affect pain include cold/humid weather, non-restorative sleep, physical and mental fatigue, excessive physical activity, physical inactivity, anxiety and stress.
  
  

• Fatigue
  In today's world many people complain of fatigue; however, the fatigue of FM is much more than being tired after a particularly busy day or after a sleepless night. The fatigue of FM is an all-encompassing exhaustion that can interfere with occupational, personal, social or educational activities. Symptoms include profound exhaustion and poor stamina
  
  

• Sleep problems
  Many fibromyalgia patients have an associated sleep disorder that prevents them from getting deep, restful, restorative sleep. Medical researchers have documented specific and distinctive abnormalities in the Stage 4 deep sleep of FM patients. During sleep, individuals with FM are constantly interrupted by bursts of awake-like brain activity, limiting the amount of time they spend in deep sleep.
  
  

• Other symptoms/overlapping conditions
  Additional symptoms may include: irritable bowel and bladder, headaches and migraines, restless legs syndrome (periodic limb movement disorder), impaired memory and concentration, skin sensitivities and rashes, dry eyes and mouth, anxiety, depression, ringing in the ears, dizziness, vision problems, Raynaud's Syndrome, neurological symptoms, and impaired coordination.

Currently there are no laboratory tests available for diagnosing fibromyalgia. Doctors must rely on patient histories, self-reported symptoms, a physical examination and an accurate manual tender point examination. This exam is based on the standardized American College of Rheumatology (ACR) criteria. Proper implementation of the exam determines the presence of multiple tender points at characteristic locations. 

It is estimated that it takes an average of five years for an FM patient to get an accurate diagnosis. Many doctors are still not adequately informed or educated about FM. Laboratory tests often prove negative and many FM symptoms overlap with those of other conditions, thus leading to extensive investigative costs and frustration for both the doctor and patient. Another essential point that must be considered is that the presence of other diseases, such as rheumatoid arthritis or lupus, does not rule out an FM diagnosis. Fibromyalgia is not a diagnosis of exclusion and must be diagnosed by its own characteristic features. 

To receive a diagnosis of FM, the patient must meet the following diagnostic criteria:

• Widespread pain in all four quadrants of the body for a minimum duration of three months

• Tenderness or pain in at least 11 of the 18 specified tender points when pressure is applied
