What Is Fibromyalgia?
Fibromyalgia is the most common musculoskeletal condition after osteoarthritis. Still, it is often misdiagnosed and misunderstood. Its characteristics include widespread muscle and joint pain and fatigue as well as other symptoms. Fibromyalgia can lead to depression and social isolation.
This overview of fibromyalgia syndrome (FMS) covers symptoms, diagnosis and treatment, and the impact fibromyalgia has on lives. The impact comes from the tremendous physical and psychological strains that come with FMS. Those strains can lead to loss of work hours, reduced income, and even job loss.
Whom does fibromyalgia affect?
Fibromyalgia affects predominantly women (over 80% of those affected are women) between the ages of 35 and 55. Less commonly, fibromyalgia can also affect men, children, and the elderly. It can occur independently or can be associated with another disease, such as systemic lupus or rheumatoid arthritis. The prevalence of fibromyalgia varies in different countries. In Sweden and Britain, 1% of the population is affected by fibromyalgia. In the United States, approximately 4% of the population has fibromyalgia.
What are fibromyalgia symptoms and signs?
The universal symptom of fibromyalgia is pain. As mentioned earlier, the pain in fibromyalgia is not caused by tissue inflammation. Instead, these patients seem to have an increased sensitivity to many different sensory stimuli and an unusually low pain threshold. Minor sensory stimuli that ordinarily would not cause pain in individuals can cause disabling, sometimes severe pain in patients with fibromyalgia. The body pain of fibromyalgia can be aggravated by noise, weather change, and emotionalstress.
The pain of fibromyalgia is generally widespread, involving both sides of the body. Pain usually affects the neck, buttocks, shoulders, arms, the upper back, and the chest. "Tender points" are localized areas of the body that are tender to light touch. Fibromyalgia tender points, or pressure points, are commonly found around the elbows, shoulders, knees, hips, back of the head, and the sides of the breastbone and are typical signs of fibromyalgia.Fibromyalgia Tender Points Diagram
Fibromyalgia "tender points" are sometimes incorrectly referred to as "trigger points," which is terminology that is used to describe a situation whereby pressing on certain trigger points can initiate a sequence of symptoms. This is not the case with fibromyalgia tender points, which are chronically a focus of pain and tenderness in the particular area involved.
Fatigue occurs in 90% of patients. Fatigue may be related to abnormal sleep patterns commonly observed in these patients. Normally, there are several levels of depth of sleep. Getting enough of the deeper levels of sleep may be more important in refreshing a person than the total number of hours of sleep. Patients with fibromyalgia lack the deep, restorative level of sleep, called "non-rapid eye movement" (non-REM) sleep. Consequently, patients with fibromyalgia often awaken in the morning without feeling fully rested, even though they seem to have had an adequate number of hours of sleep time. Some patients awaken with muscle aches or a sensation of muscle fatigue as if they had been "working out" all night!
Mental and/or emotional disturbances occur in over half of people with fibromyalgia. These symptoms include poor concentration, forgetfulness, and memory problems, as well as mood changes, irritability, depression, andanxiety. Since a firm diagnosis of fibromyalgia is difficult and no confirmatory laboratory tests are available, patients with fibromyalgia are often misdiagnosed as having depression as their primary underlying problem.
Other symptoms of fibromyalgia include migraine and tension headaches, numbness or tingling of different parts of the body, abdominal pain related to irritable bowel syndrome ("spastic colon"), and irritable bladder, causingpainful and frequent urination. Like fibromyalgia, irritable bowel syndrome can cause chronic abdominal pain and other bowel disturbances without detectable inflammation of the stomach or the intestines.
Each patient with fibromyalgia is unique. Any of the above symptoms can occur intermittently and in different combinations.
What Tests Are Used to Diagnose Fibromyalgia?
There are no specific laboratory tests to diagnose fibromyalgia. To make an accurate diagnosis, your doctor will rely on a comprehensive physical exam and your medical history. Fibromyalgia is mostly a diagnosis of exclusion. That means the doctor will rule out other conditions that could cause similar symptoms.
To rule out more serious illnesses, your doctor may run some specific blood tests. For example, your doctor may ask for a complete blood count (CBC). The doctor may also ask for tests for chemicals, such as glucose, that can create problems similar to problems caused by fibromyalgia. A thyroid test may also be done. An underactive thyroid (hypothyroidism) can cause problems similar to fibromyalgia. That includes fatigue, muscle aches, weakness, and depression.
Other laboratory tests used to rule out serious illnesses may include Lyme titers,antinuclear antibodies (ANA), rheumatoid factor (RF), erythrocyte (red blood cell) sedimentation rate (ESR), prolactin level, calcium level, and vitamin D level.
Your doctor may see if your symptoms satisfy the diagnostic criteria for fibromyalgia syndrome outlined by the American College of Rheumatology. These criteria include widespread pain that persists for at least three months. Widespread pain refers to pain that occurs in both the right and left sides of the body, both above and below the waist, and in the chest, neck, and mid or lower back. The criteria also include the presence of tender points at various spots on the body.
The doctor will evaluate the severity of related symptoms such as fatigue, sleep disturbances, and mood disorders. This will help measure the impact FMS has on your physical and emotional function as well as on your overall health-related quality of life.
Are There Alternative Treatments for Fibromyalgia?
Alternative therapies, although they are not well-tested, can help manage the symptoms of fibromyalgia. For instance, therapeutic massage manipulates the muscles and soft tissues of the body and helps ease deep muscle pain. It also helps relieve pain of tender points, muscles spasms, and tense muscles. Similarly, myofascial release therapy, which works on a broader range of muscles, can gently stretch, soften, lengthen, and realign the connective tissue to ease discomfort.
The American Pain Society recommends moderately intense aerobic exercise at least two or three times a week. They also endorse clinician-assisted treatments, such as hypnosis, acupuncture, therapeutic massage, and chiropractic manipulation for pain relief.
Along with alternative therapies, it's important to allow time each day to rest and relax. Relaxation therapies -- such as deep muscle relaxation or deep breathing exercises -- may help reduce the added stress that can trigger fibromyalgia symptoms. Having a regularly scheduled bedtime is also important. Sleep is essential to let the body repair itself.
