More Information on Low Back Pain
Chronic low back pain is among the most common chronic pain syndromes,
affecting men and women equally. If left untreated, it can cause unnecessary
suffering and upset a person's life at home and on the job. The good
news is that a wide range of treatment options are readily available
to successfully reduce or manage this type of pain.
Chronic low back pain frequently affects people in their prime working
years and, as a result, it is the single largest cause of lost work
days and lost income. It also accounts for more than 25 percent of all
workers' compensation claims, with a great cost to society. Additionally,
while studies show that many sufferers do not seek medical attention,
chronic low back pain remains a primary reason for hospital and physician
The symptoms of chronic low back pain are varied, making a precise
diagnosis often difficult. Low back pain is considered chronic if it
persists for more than three months. Many people have a limited range
of motion or tender areas. In addition to the actual back pain, some
people may experience fever or weight loss, which can indicate illness
or infection. Psychological symptoms also may occur.
Depression has been shown to be three to four times as prevalent in
patients with chronic back pain as in the general population.
Chronic low back pain can be shooting, stabbing, localized in nature,
or referred from another part of the body. In some cases, people with
chronic low back pain are found to have distinct pain syndromes, including
arthritis, myofascial pain with muscle spasm, degenerative joint disease
and radiculopathic pain (pinched nerve). They may experience this pain
only when walking, sitting or standing, each action suggesting a specific
root cause. Whatever its degree and nature, chronic low back pain should
always be evaluated by a physician to rule out any serious problems.
The Causes of Back Pain
There are many pain-sensitive structures in the back. Injuries, infection
or inflammation affecting these structures are often the origin of chronic
low back pain. Most cases result from simple sprains or strains of the
muscles and ligaments. Others may be related to bruises and disk herniations.
How Is Chronic Low Back Pain Diagnosed?
Diagnosis of chronic low back pain, as well as of its many related syndromes,
relies heavily on a thorough physical examination and blood work-up,
a complete medical and psychosocial history, and a description of the
pain, including its location and how it started. While a good physical
exam focuses on obvious deformities, tender areas, range of motion and
neurologic function, it also can shed light on problems not easily diagnosed
that involve the muscles, connective tissue, nerves and spine. There
are special maneuvers that should be performed so that the physician
can correctly assess and distinguish the many possible causes of chronic
low back pain.
Imaging techniques may be necessary if there is tenderness over the
spine or the patient's history indicates the possibility of a tumor
or infection. Magnetic resonance imaging (MRI) is used to evaluate tissue,
bone, muscles and nerves; computed tomography (CT) provides three-dimensional
images of internal structures such as organs; and myelography and electromyelography
inject contrast dyes into the spine to produce pictures of the spinal
cord. Simple X-rays can be very useful in determining such conditions
as osteoporosis and spondylolisthesis.
Other more advanced diagnostics -- thermography, diskography and electrophysiologic
studies among them -- also are sometimes necessary.
|| Thermography converts measurements of body heat,
increased by inflammation or infection, into visual signals that
can be photographically recorded.
||Diskography takes pictures of vertebrae in the spine
following the injection of radiopaque chemicals that can withstand
radiation and X-rays to identify areas producing pain.
|| Electrophysiologic studies examine the electrical
aspects of body functions.
When no physical reason for the pain can be identified, treatment can
be difficult to determine, necessitating a multidisciplinary approach
to care. In addition, depression, stress or other psychological dysfunction
should be treated at the same time.
|Treatment for chronic low back pain may last from
a few weeks to several months, and usually takes a multimodality
approach, in which several different therapies (drug, physical,
interventional, complementary, psychological) are used in combination
with one another. View the Flash presentation to learn more.
Drug Therapy. Medications may include nonsteroidal anti-inflammatory
drugs (NSAIDs), adjuvant analgesics (like antidepressants and anticonvulsants),
and opioids. Long-term opioid therapy may be appropriate for carefully
selected patients who can be monitored by their physicians and who can
appropriately manage their medication.
Physical Therapy. Walking, swimming or cycling on a stationary bike
can provide general conditioning and help strengthen weakened muscles
while minimizing the stress on the spine. Therapy is tailored to the
patient, with gradual increases in duration.
Interventional Therapy. One way to alleviate chronic low back pain
is to block or numb pain pathways. This is accomplished through a variety
of invasive treatments, including epidural steroids, injections, joint
and nerve blocks and analgesic pump devices.
Complementary Therapy. Used in combination with analgesic treatments,
complementary therapy incorporates a wide range of practices that are
thought to prompt the body's release of pain-relieving substances. They
include acupuncture, massage, meditation, herbal remedies, chiropractics
and hot and cold packs. Visit our Low Back Pain pages on
HealingChronicPain.org to learn more about state-of-the-art therapies.
Psychological Therapy. Some patients can benefit from counseling (single
or group). Employee assistance programs, located at the job site, and
often free of charge, can also help.
Some patients with chronic lower back pain may require surgery as a
final alternative. And, for some patients who are particularly disabled,
a formal program administered by a multidisciplinary pain center may
