General Discussion

Fibromyalgia is a chronic disorder characterized by pain throughout much of the body. The pain may begin gradually or have a sudden onset. Other symptoms are muscle spasms, fatigue, muscle tissue stiffness and non- restorative (unrefreshing) sleep. The exact cause of this disorder is unknown.



The terms Fibrositis, Fibromyositis, Periarticular Fibrositis and Rheumatoid Myositis are still being used by many to describe this condition. The ending of "itis" on each of these terms is actually incorrect. "Itis" means inflammation, and there is no inflammation in Fibromyalgia. The term Fibromyalgia has now become the accepted term, but many people continue to be diagnosed with the other synonyms. Tension Myalgia is another synonym that is currently being used.

Symptoms

Patients with Fibromyalgia may have a gradual or sudden onset of symptoms. The major symptom of this disorder is muscular pain. Areas which are frequently affected may include muscles in the back of the neck and shoulders, in the low back, the sides of the breast bone, and the bony points of the elbows, hips and knees. In addition, small specific areas called tender points, which are painful when pressure is applied, will be found by an examining physician.



Other symptoms found in most patients with Fibromyalgia are: muscle spasms, fatigue, muscle stiffness and non-restorative (unrefreshing) sleep.



Some patients with fibromyalgia may have chest pain, painful menstrual periods, difficulty concentrating, headaches, painful and/or frequent urination, diarrhea, constipation, numbness, dryness in the eyes and mouth, dizziness, swelling of a tendon (tendinitis), swelling of the connective tissue structure surrounding a joint (bursitis), depression and/or anxiety.

Causes

The exact cause of Fibromyalgia is not known. Researchers are studying serotonin, a chemical in the brain (neurotransmitter), to see if there is a disturbance in the messages sent between various parts of the central nervous system in people with Fibromyalgia. An imbalance of serotonin could have a hand in the increase of pain, depression and unrefreshing sleep associated with Fibromyalgia.



Muscle tissue, hormonal and immunological influences, as well as the possibility of a virus triggering the disorder are all being investigated by researchers.

Affected Populations

Fibromyalgia is diagnosed more frequently in females than in males. The majority of patients with this disorder will develop symptoms between the ages of 20 and 50 years. It is estimated that 3.7 million Americans are affected by Fibromyalgia.



Fibromyalgia may also develop in children and teenagers, often being misdiagnosed as "growing pains."

Standard Therapies

Fibromyalgia may be treated with low doses of tricyclic antidepressant medications. Amitriptyline (Elavil) and Cyclobenzaprine (Flexeril), which are prescribed as muscle relaxants, may be helpful. They may also help patients who suffer from unrefreshing (non-restorative) sleep. The tricyclic antidepressant amitriptyline (Elavil) can also be used to help patients with this disorder who have depression. When Elavil is used for this reason, it is given at higher doses.



Some patients receive temporary relief with stretching exercises, deep heat treatments, warm showers and baths, whirlpool baths and hot tubs, heating pads, massages, ice packs, acupuncture, biofeedback and/or aerobic exercise.
