While the underlying cause or causes of FM still remain a mystery, new research findings continue to bring us closer to understanding the basic mechanisms of fibromyalgia. Most researchers agree that FM is a disorder of central processing with neuroendocrine/neurotransmitter dysregulation. The FM patient experiences pain amplification due to abnormal sensory processing in the central nervous system. An increasing number of scientific studies now show multiple physiological abnormalities in the FM patient, including: increased levels of substance P in the spinal cord, low levels of blood flow to the thalamus region of the brain, HPA axis hypofunction, low levels of serotonin and tryptophan and abnormalities in cytokine function.
Recent studies show that genetic factors may predispose individuals to a genetic susceptibility to FM. For some, the onset of FM is slow; however, in a large percentage of patients the onset is triggered by an illness or injury that causes trauma to the body. These events may act to incite an undetected physiological problem already present.
Exciting new research has also begun in the areas of brain imaging and neurosurgery. Ongoing research will test the hypothesis that FM is caused by an interpretative defect in the central nervous system that brings about abnormal pain perception. Medical researchers have just begun to untangle the truths about this life-altering disease.
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.
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.
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.
Tender Points Illustration Front and BackDiagnosis
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
One of the most important factors in improving the symptoms of FM is for the patient to recognize the need for lifestyle adaptation. Most people are resistant to change because it implies adjustment, discomfort and effort. However, in the case of FM, change can bring about recognizable improvement in function and quality of life. Becoming educated about FM gives the patient more potential for improvement.
An empathetic physician who is knowledgeable about the diagnosis and treatment of FM and who will listen to and work with the patient is an important component of treatment. It may be a family practitioner, an internist, or a specialist (rheumatologist or neurologist, for example). Conventional medical intervention may be only part of a potential treatment program. Alternative treatments, nutrition, relaxation techniques, and exercise play an important role in FM treatment as well. Each patient should, with the input of a healthcare practitioner, establish a multifaceted and individualized approach that works for them.
* Pain management
A number of pharmacological treatments for fibromyalgia are available for prescription. The first to be approved by the U.S. Food and Drug Administration to treat fibromyalgia was pregabalin (Lyrica®); the second was duloxetine (Cymbalta®); and the third was milnacipran (Savella®). Other FM medications are currently in development, and may soon receive FDA approval to treat fibromyalgia. Additionally, healthcare providers may treat patients' FM symptoms with non-narcotic pain relievers (e.g. tramadol) or low doses of antidepressants (e.g. tricyclic antidepressants, serotonin reuptake inhibitors) or benzodiazepines. Patients must remember that antidepressants are "serotonin builders" and can be prescribed at low levels to help improve sleep and relieve pain. If the patient is experiencing depression, higher levels of these or other medications may need to be prescribed. Lidocaine injections into the patient's tender points also work well on localized areas of pain. An important aspect of pain management is a regular program of gentle exercise and stretching, which helps maintain muscle tone and reduces pain and stiffness.
* Sleep management
Improved sleep can be obtained by implementing a healthy sleep regimen. This includes going to bed and getting up at the same time every day; making sure that the sleeping environment is conducive to sleep (i.e. quiet, free from distractions, a comfortable room temperature, a supportive bed); avoiding caffeine, sugar, and alcohol before bed; doing some type of light exercise during the day; avoiding eating immediately before bedtime; and practicing relaxation exercises as you fall to sleep. When necessary, there are new sleep medications that can be prescribed, some of which can be especially helpful if the patient's sleep is disturbed by restless legs or periodic limb movement disorder.
* Psychological support
Learning to live with a chronic illness often challenges an individual emotionally. The FM patient needs to develop a program that provides emotional support and increases communication with family and friends. Many communities throughout the United States and abroad have organized fibromyalgia support groups. These groups often provide important information and have guest speakers who discuss subjects of particular interest to the FM patient. Counseling sessions with a trained professional may help improve communication and understanding about the illness and help to build healthier relationships within the patient's family.
* Other treatments
Complementary therapies can be very beneficial. These include: physical therapy, therapeutic massage, myofascial release therapy, water therapy, light aerobics, acupressure, application of heat or cold, acupuncture, yoga, relaxation exercises, breathing techniques, aromatherapy, cognitive therapy, biofeedback, herbs, nutritional supplements, and osteopathic or chiropractic manipulation.
While there is currently no cure for fibromyalgia, better ways to diagnose and treat the chronic pain disorder continue to be developed. Since June 2007, the U.S. Food and Drug Administration has approved three medications for the treatment of fibromyalgia and other FM medications are currently in development. Research efforts have expanded as well. In 1990 there were approximately 200 published research papers on fibromyalgia studies. Today there are more than 4,000 published reports.
While many strides have been made in the last decade, fibromyalgia remains a challenging condition. However, clinical studies have demonstrated that fibromyalgia patients can reduce their symptoms through a variety of treatment options. Working in conjunction with knowledgeable healthcare professions, motivated and informed patients can experience significant improvement in their symptoms and quality of life. Developing an individualize self-management plan, from identifying effective treatments approaches to making necessary lifestyle changes, will further improve one’s health.
