Fibromyalgia
Alternative names
Fibromyositis; Fibrositis;
Myofascial pain syndrome
Definition
Fibromyalgia is a common condition characterized
by widespread pain in joints, muscles, tendons,
and other soft tissues. Some other problems
commonly linked with fibromyalgia include fatigue,
morning stiffness, sleep problems, headaches,
numbness in hands and feet, depression, and anxiety.
Fibromyalgia can develop on its own, or secondary
to other musculoskeletal conditions, such as
rheumatoid arthritis, or systemic lupus.
Diagnosis of fibromyalgia requires a history
of a least three months of widespread pain,
and pain and tenderness in at least 11
of 18 tender-point sites. These tender-point
sites include fibrous tissue or muscles of the:
- Neck
- Shoulders
- Chest
- Rib cage
- Lower back
- Thighs
- Knees
- Arms (elbows)
- Buttocks
The overwhelming characteristic of fibromyalgia
is long-standing, body-wide pain with defined
tender points. Tender points are distinct
from trigger points seen in other pain syndromes.
(Unlike tender points, trigger points can
occur in isolation and represent a source of
radiating pain, even in the absence of direct
pressure.)
Fibromyalgia pain can mimic the pain experienced
by people with various types of arthritis. With
fibromyalgia syndrome alone, the significant
joint swelling, destruction, and deformity seen
in patients with diseases, such as rheumatoid
arthritis does not occur.
The soft-tissue pain of fibromyalgia is described
as deep-aching, radiating, gnawing, shooting
or burning, and ranges from mild to severe.
Fibromyalgia sufferers tend to waken with body
aches and stiffness.
For some patients, pain improves during the
day and increases again during the evening,
though many patients with fibromyalgia have
day-long, unrelenting pain. Pain can increase
with activity; cold, damp weather; anxiety;
and stress.
Causes
and risks
The cause of this disorder is unknown. Physical
or emotional trauma may play a role in development
of the syndrome. A number of lines of evidence
suggest that fibromyalgia patients have abnormal
pain transmission responses.
It has been suggested that sleep disturbances,
which are common in fibromyalgia patients, may
actually cause the condition. Another hypothesis
suggests that the disorder may be associated
with changes in skeletal muscle metabolism,
possibly caused by decreased blood flow, which
could cause chronic fatigue and weakness.
Others have suggested that an infectious
microbe, such as a virus, triggers the illness.
At this point, no such virus or microbe has
been identified.
Pilot studies have shown a possible inherited
tendency toward the disease, though evidence
is very preliminary.
The disorder has an increased frequency among
women 20 to 50 years old. The prevalence of
the disease has been estimated between 0.7%
and 13% for women, and between 0.2% and 3.9%
for men.
Prevention
There is no proven prevention for this disorder.
However, over the years, the treatment
and management of the disease has improved.
Symptoms
- Multiple tender areas (muscle and joint
pain) on the back of the neck, shoulders,
sternum, lower back, hip, shin, elbows, knees.
- Fatigue
- Sleep disturbances
- Body aches
- Reduced exercise tolerance
- Chronic facial muscle pain or aching
Signs
and tests
A number of tests may be done to rule out other
disorders. An examination reveals multiple tender
areas on the back of the neck, shoulders, sternum,
lower back, hip, shin, elbows, or knees.
Sometimes, laboratory and X-ray tests are done
to help confirm the diagnosis. The tests
will also rule out other conditions that may
have similar symptoms.
Other underlying ailments, such as chronic
fatigue syndrome, irritable bowel syndrome,
and rheumatoid arthritis, can also be present.
New patients should be checked for these underlying
conditions as well as fibromyalgia.
Treatment
In mild cases, symptoms may go away when stress
is decreased or lifestyle changes are implemented.
A combination of treatments including
medications, patient education, physical therapy,
and counseling are usually recommended.
Many fibromyalgia sufferers have found support
groups helpful.
Certain classes of antidepressant medications
are sometimes prescribed for the disorder. Studies
show that antidepressants in low doses can decrease
depression, relax craniofacial and skeletal
muscles, improve sleep quality, and release
pain-killing endorphins. Other medications that
are used include anti-inflammatory pain medications
and medications that work on pain transmission
pathways, such as Gabapentin.
Eating a well-balanced diet, and avoiding caffeine may
help with problems sleeping, and may help
reduce the severity of the symptoms. Lifestyle
measures to improve the quality of sleep can
be effective for fibromyalgia.
Some reports indicate that fish oil, magnesium/malic
acid combinations, or vitamins may be effective.
Reducing stress and improving coping skills
may also help reduce painful symptoms.
Improved fitness through exercise is recommended.
Studies have shown that fibromyalgia symptoms
can be relieved by aerobic exercise. The
best way to begin a fitness program is to start
with low impact exercises, like walking and
swimming.
Starting slowly helps stretch and mobilize
tight, sore muscles. High-impact aerobics and
weight lifting could cause increased discomfort.
Gentle stretching and light massage may help
relieve symptoms, as well as acupressure,
acupuncture, and relaxation techniques.
Severe cases of fibromyalgia may require a
referral to a pain clinic.
Prognosis
Fibromyalgia is a common and chronic problem.
The symptoms sometimes improve. At other times,
the symptoms may worsen and continue for months
or years. The key is seeking professional help which
includes a multi-faceted approach to the
management and treatment of the disease.
There is no proof that fibromyalgia syndrome
results in an increased death rate.
