What is Fibromyalgia (FMS)?
A clinical syndrome characterized by
widespread muscular pain (usually
chronic),
fatigue and
muscle tenderness (tender points)
What is FMS? (cont.)
Additional symptoms are common and
include:
- poor sleep almost always
- headaches
- irritable bowel syndrome
- cognitive and memory problems
“fibro fog”
- numbness and tingling in fingers and toes
What is FMS? (cont.)
- irritable bladder
- temporomandibular joint (TMJ) disorder
- restless leg syndrome
- dry eyes and dry mouth
- morning stiffness
- anxiety and depression
Symptoms including pain may wax and wane
over time
What causes FMS?
Cause is unknown
Abnormally high levels of Substance P in
spinal fluid in some patients
Substance P important in transmission
and amplification of pain signals to and
from brain
“Volume control” is turned up too high in
brain’s pain centers
What causes FMS? (cont)
Familial tendency to develop FMS
suggests genetic role
Can be triggered by physical, emotional or
environmental stressors such as car
accidents, repetitive injuries and certain
diseases
Patients with Rheumatoid arthritis and
SLE (Lupus) are more likely to develop
FMS
What causes FMS? (cont.)
Other conditions such as Lyme disease
and obstructive sleep apnea (OSA) have
been associated with FMS
Sleep deprivation with disruption of deltawave sleep (non-REM stage IV) is
associated with day-time fatigue and
fibromyalgia syndrome
Who gets FMS?
Affects as many as 1 in 50 Americans
Most common in middle-aged women
Men and children may also develop the
disorder
Patients with RA, SLE and Ankylosing
spondylitis are more likely
Women who have a family member with
FMS are more likely to develop it
How is FMS diagnosed?
A diagnosis is made by evaluation of
symptoms and presence of tender points
American College of Rheumatology
Classification Criteria for Fibromyalgia
(1990)…….widespread pain for at least 3
months and
pain in 11 out of 18 tender point sites on
digital palpation
ACR classification criteria:
fibromyalgia
Both criteria must be satisfied
– History of widespread pain for more than 3
months, on both sides of the body, above and
below the waist, and axial skeleton (cervical
spine, anterior chest, thoracic pain, or low back)
– Pain in 11 of 18 tender point sites on digital
palpation with approximate force of 4 kg.
Presence of second clinical disorder does not
exclude diagnosis of fibromyalgia.
Fibromyalgia: tender points
(diagram)
How is FMS diagnosed? (cont.)
X-rays, blood tests, specialized scans such as
nuclear medicine and CT, muscle biopsies are
all normal
Objective “markers of inflammation” such as
ESR (erythrocyte sedimentation rate) are normal
Must be distinguished from other common
diffuse pain conditions such as RA, SLE,
Hypothyroidism and Polymyalgia Rheumatica
(PMR)
How is FMS treated?
Fibromyalgia is a chronic condition
managed with both medications and
physical modalities
Medication therapy is largely symptomatic,
as there is no definitive treatment cure for
fibromyalgia
How is FMS treated? (cont.)
Current studies suggest that the best
pharmacologic treatment for treating pain
and improving sleep disturbance includes:
- Tricyclic compounds such as
cyclobenzaprine (FLEXERIL) and
amitriptyline (ELAVIL)
- Dual reuptake inhibitors such as
venlafaxine (EFFEXOR), duloxetine
(CYMBALTA) and tramadol (ULTRAM)
- SSRIs/ antidepressants such as fluoxetine
(PROZAC), paroxetine (PAXIL) and
sertraline (ZOLOFT) for depression and
pain
- Recent studies have shown that the antiepileptics (seizure meds) gabapentin
(NEURONTIN) and pregabalin (LYRICA)
have been effective
- NSAIDs (non-steroidal anti-inflammatory drugs)
such as ibuprofen and naproxen are generally
ineffective
- Long acting opioids (narcotics) generally are not
of great benefit either
- Benzodiazepines such as diazepam (VALIUM)
and clonazepam (KLONIPIN) may be useful for
patients with restless leg syndrome or very
severe sleep disturbance who have not
responded to other therapies
N.B.
The US Food and Drug Administration
has not yet approved any medications to
treat FMS
Other Therapies for FMS
Complementary and alternative therapies
have been used although not well studied
in FMS
- Therapeutic massage
- Myofascial release therapy
- Acupuncture
Other Therapies for FMS
Patient Self-Management
- Schedule time to relax, including deep breathing
and meditation
- Establish routine for going to bed and waking up
- Aerobic exercise on regular basis
- Self-education i.e. Arthritis Foundation,
National Fibromyalgia Assn.
- Support group
- Cognitive Behavioral Therapy (CBT)
Common Misconceptions
Eleven (11) out of 18 tender points needed
to make the diagnosis of FMS
(2005 ACR Classification Criteria)
FALSE
Tenderness can be widespread without
tender points
The major symptom in FMS is pain
FALSE
A variety of neurologic abnormalities may
be described including numbness and
tingling of the extremities, cognitive and
memory problems, irritable bowel
symptoms, etc.
It’s not a real illness, it’s in the
“patient’s head”
FALSE
A real condition with severe physical effects
in some, although psychologic factors
including depression may be the major
determinant of pain in others
The prognosis is “hopeless”
FALSE
Early, aggressive treatment can prevent
physical deconditioning and loss of
function
