For nearly 20 years, social worker Susan Mason suffered from mysterious and debilitating muscle pain throughout most of her body. Time and time again, doctors told Mason that she just had the flu, or that she was depressed and the aches would eventually go away on their own. But they never did. "It just hurt too badly for me to believe there wasn't something wrong," Mason says.

Finally in 1999, during a period of intense pain, Mason called a university hospital in West Virginia to make an appointment with a rheumatologist, a medical specialist who treats arthritis and certain autoimmune disorders. Although there were no appointments available for months, the nurse who answered the phone that day mentioned one word that would change Mason's life: fibromyalgia.

Shortly thereafter, a doctor diagnosed Mason with fibromyalgia syndrome, or FMS. The diagnosis brought peace of mind to the recently retired West Virginia resident by giving her some concrete knowledge of what she was dealing with. She also learned that, while fibromyalgia has no known cure, many people who have it benefit greatly from treatment.

An estimated 2 to 4 percent of Americans -- most of them women -- are thought to suffer from fibromyalgia, according to the American College of Rheumatology. Fibromyalgia is a chronic disorder characterized by widespread pain in the muscles and soft tissues surrounding joints, which is often accompanied by fatigue and sleep disturbances. Twenty years ago, the condition was virtually unheard of. Today, doctors are making a push to better diagnose, understand, and treat the condition.

Pain is the main symptom. Although fibromyalgia may leave you feeling achy all over, you're most likely to feel sharper pain where muscles attach to joints or in soft tissue areas called trigger points. Places that may be especially painful include the elbow, forearm, hip, knee, shoulder, neck, jaw, and back. The condition causes pain in the body's fibrous ligaments, tendons, and muscles.

Fatigue and difficulty sleeping are other common symptoms. Research in sleep labs has shown that people with fibromyalgia don't get enough deep sleep, and their sleep is frequently interrupted. They often wake up in the morning feeling unrefreshed. In some people, fibromyalgia may also be associated with depression, anxiety, headaches, and digestive-system problems, like irritable bowel syndrome.

No one knows what causes it. However, people with it have high levels of Substance P in their spinal fluid, a chemical that transmits and amplifies pain signals. Researchers believe it may be triggered by injury, stress, anxiety, chronic lack of sleep, or certain viral infections. It runs in some families, which suggests it might have a genetic component. Some of the most promising research in the past few years centers on the idea that fibromyalgia is a malfunction in the way the brain perceives pain. In other words, fibromyalgia sufferers may have a lower pain threshold than other people because of a neurochemical imbalance, which causes the brain to interpret ordinary sensations as pain.

No blood test or x-ray can detect the disorder. This is one reason doctors have had difficulty diagnosing the condition over the years.

A combination of relatively constant, long-lasting pain (three months or more) coupled with fatigue and sleep disturbances that have no other known source suggest that you have fibromyalgia. To confirm this suspicion, your doctor will conduct a physical exam to determine how much pain you're experiencing. In 1990, the American College of Rheumatology developed criteria that physicians use to diagnose fibromyalgia: A person must have widespread pain in combination with tenderness in at least 11 of 18 specific sites, or trigger points, on the body, to be diagnosed with the condition. Your doctor will likely apply pressure to these specific points located around the neck, shoulders, elbows, hips, and knees to record your pain levels. However, physicians today may diagnose fibromyalgia even without meeting the tender point criteria.

Many people believe fibromyalgia is a psychological disorder, rather than a true physical condition, or that the sufferer is imagining the pain or simply pretending to hurt. "The majority of people, even doctors, still have the idea that this is a psychological condition, or that these women are faking [their pain]," says Dr. Atul Deodhar, a rheumatologist and fibromyalgia expert at the Oregon Health & Science University in Portland.

Deodhar points to numerous scientific studies which prove that fibromyalgia sufferers experience true physical pain. In one study published in May 2002 issue of Arthritis & Rheumatism, researchers used a functional MRI to do brain imaging to measure the brain's response to pain in 16 fibromyalgia patients and 16 healthy people. In the first part of the experiment, they found that applying adequate pressure to the thumbs stimulated similar pain in both groups -- and similar blood flow in the brain. In the second test, however, researchers found that the brains of fibromyalgia patients became highly active when only slight pressure was applied to their thumbs; in healthy people, when the same pressure was applied to the thumbs, the pain centers were far less active.

No, but they share the same two defining symptoms: pain and fatigue. In chronic fatigue syndrome, fatigue is the primary symptom, whereas in fibromyalgia, pain is the chief complaint. However, some people who have chronic fatigue syndrome also have fibromyalgia. Recent research suggests that these two disorders, both incompletely understood, may be at two ends of the spectrum of a common underlying problem.

For starters, try to find a physician who is familiar with the disorder. You'll probably have to shop around and ask a lot of questions. Many rheumatologists treat fibromyalgia, but may be unfamiliar with it. Physiatrists, family physicians, internists, specialists in physical medicine and rehabilitation, and doctors at pain clinics also treat the condition.

Although many fibromyalgia sufferers augment their therapy with alternative methods, it's important to begin any treatment by seeing a conventional physician, since many other disorders -- including certain infections and autoimmune diseases -- can cause some of the same symptoms. Experts from the American Pain Society Fibromyalgia Panel recommend a multidisciplainary treatment plan that combines Patient education, medication (including pain medicine, muscle relaxants, fatigue medicine, or antidepressants), physical therapy (massage, stretching, and gentle aerobics), and cognitive behavioral therapy. There is only one medication that is approved for the treatment of fibromyalgia. Pregabalin (Lyrica), an anti-seizure medication, has been shown to be effective in treating pain, anxiety and sleep problems in people with fibromyalgia. Gabapentin (Neurontin) is another anti-seizure medication that is sometimes prescribed off-label (meaning it is not FDA-approved for that particular condition) for fibromyalgia as well.

Depression, stress, and anxiety have been linked to fibromyalgia. However, it isn't clear whether these mental ailments contribute to the syndrome or are a result of it. "We know that if you are depressed and anxious, your aches and pains are worse, and that if your aches and pains are very bad, you may become depressed and anxious," says Deodhar. But it is difficult to know which came first." Antidepressants appear to help many patients with fibromyalgia even if they don't seem to be clinically depressed.

Increased public awareness about fibromyalgia has given many sufferers hope for a better understanding of the condition. In 1998, signaling a significant change in priority, the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a branch of the National Institutes of Health, allocated $3.6 million for fibromyalgia research. Ten years later, the NIH spends about $12 million per year on fibromyalgia research.

In the meantime, people with fibromyalgia continue to experiment with different methods of managing their pain. For Susan Mason, the past three years have been a process of trial and error to find the best treatments. Antidepressants didn't work for her, but ibuprofen and muscle relaxants did. Gentle aerobic exercise has been most beneficial of all, she says, and the occasional massage works wonders.

"Most of all, I recommend finding a good doctor and starting an exercise program," says Mason, now 62. "It hasn't taken all the pain away, but it's made it tolerable."

•Develop a plan with your doctor. Discuss lifestyle changes you can make to improve your sleep and relieve pain. These are likely to include changes in diet and exercise, and may also mean taking medication like anti-anxiety drugs, sleeping pills, pain relievers, or antidepressants.

•Exercise. Low levels of exercise -- as hard as it sounds when you are aching and exhausted -- will ultimately improve your energy and ease pain.

•Get some sleep. Learn about "sleep hygiene" by reading up on insomnia. Beds with air pockets or Swedish foam beds may relieve nighttime pressure on pain points. Avoid drinking alcohol or taking other substances before going to bed that can have a negative impact on the quality of sleep you get. Don't eat or drink just before bedtime.

•Find a support group. Fibromyalgia is a chronic condition that you'll have to learn to live with. Support groups can be a tremendous source of comfort, especially if the people you interact with at home or work don't understand what you're going through. Talking with a mental health therapist can help you manage the depression and anxiety that occasionally accompany fibromyalgia.

Educating yourself about how to manage your pain will also help. Plug into the online network of fibromyalgia support groups, self-help sites, and medical resources available on the Web sites of the Arthritis Foundation, Fibromyalgia Network, and other organizations.
