Lower Back Pain: A Common Problem
Back pain is a common neurological ailment. Men and women are equally affected. It occurs most often between ages 30 and 50, due in part to the aging process but also as a result of sedentary life style.
Job Disability
Lower back pain is a common cause of job-related disability and missed work. Most occurrences of lower back pain go away within a few days. Others take much longer to resolve or lead to more serious conditions.
Acute Lower Back Pain
Acute back pain generally lasts from a few days to a few weeks. Most acute back pain is mechanical in nature, the result of trauma to the lower back or a disorder such as arthritis.
Pain from trauma may be caused by:
Symptoms
Symptoms may range from muscle ache to shooting or stabbing pain, limited flexibility and/or range of motion, or an inability to stand straight.
Lower back pain unrelated to injury or other known cause is unusual in pre-teen children, although, heavy backpacks can strain the back.
Chronic Lower Back Pain
Chronic back pain is measured by duration, pain that persists for more
than 3 mo's is considered chronic
● It is often progressive and the cause can be
difficult to determine.
Risks of lower back pain from disc disease or spinal degeneration increase with age
Part 2 of 10 - What Structures Make Up The Lower Back? (Anatomy of the Back)
The Back Is An Intricate Structure
Spinal Column
The centerpiece is the spinal column, which supports the upper body’s weight and houses and protects the spinal cord. Stacked on top of one another are more than 30 bones (the vertebrae) that form the spinal column or spine. Each of these bones contains a roundish hole that, when stacked in register with the others, creates a channel that surrounds the spinal cord.
Spinal Cord
The spinal cord descends from the base of the brain to just below the rib cage. Small nerves (roots) enter and emerge from the spinal cord through spaces between the vertebrae.
Cauda Equina
Because the bones of the spinal column continue growing after the spinal cord reaches its full length in early childhood, the nerve roots to the lower back and legs extend many inches down the spinal column before exiting.
This bundle of nerve roots is known as the cauda equina, or the "horse’s tail".Other Structures Of The Back
Spaces between the vertebrae contain round, spongy pads of cartilage called intervertebral discs that allow for flexibility in the lower back. Bands of tissue known as ligaments and tendons hold the vertebrae in place and attach the muscles to the spinal column.
Four Regions
Starting at the top, the spine has 4 regions:
The lumbar region of the back, where most back pain is felt, supports the weight of the upper body
Part 3 of 10 - What Causes Lower Back Pain?
Aging Process
As people age, bone strength and muscle elasticity and tone tend to decrease. The discs begin to lose fluid and flexibility, which decreases their ability to cushion the vertebrae.
Injury & Trauma
Pain can occur when, for example, someone lifts something too heavy or overstretches, causing a sprain, strain, or spasm in one of the muscles or ligaments in the back.
If the spine becomes overly strained or compressed, a disc may rupture or
bulge outward. This rupture may put pressure on one of the more than 50
nerves rooted to the spinal cord that control body movements and transmit
signals from the body to the brain.
When these nerve roots become compressed or irritated, back pain results.
Low back pain may also reflect:
Other Causes
Most low back pain follows injury or trauma to the back, but pain may also be caused by:
Other Factors
Other factors that contribute to low back pain include:
Serious Problems
Low back pain may also indicate a more serious medical problem. People with back pain along with fever, loss of bowel or bladder control, pain when coughing, progressive weakness or pain radiating into the legs should contact a doctor immediately to help prevent permanent damage
Part 4 of 10 - What Conditions Are Associated With Lower Back Pain? Associated Conditions
Conditions that may cause low back pain and require treatment by a doctor or health specialist include:
Those with spinal degeneration may experience back stiffness upon awakening or may feel pain after walking or standing for a long time.
●Spinal stenosis related to congenital narrowing of the bony canal predisposes some people to pain related to disc disease.
●Skeletal irregularities such as scoliosis, kyphosis, lordosis, back extension and flexion can produce strain on the vertebrae and supporting muscles, tendons, ligaments, and tissues.
Other Conditions
Other conditions associated with low back pain include:osteoporosis (a progressive bone disease)
fibromyalgia (a chronic disorder with widespread musculoskeletal pain)
ankylosing spondylitis (a chronic spine arthritis)
osteomyelitis (a bone infection)
sacroiliitis (inflamed sacroiliac joints)
Part 5 of 10 - How is Lower Back Pain Diagnosed?
Diagnosis
A thorough medical history and physical exam can usually identify any dangerous conditions or family history that may be associated with the pain. The patient describes:
The physician will examine the back and conduct neurologic tests to determine the cause of pain and appropriate treatment. Blood tests may also be ordered. Imaging tests may be necessary to diagnose tumors or other possible sources of the pain.
Diagnostic Methods
Diagnostic methods that may be used include:
Part 6 of 10 - How is Lower Back Pain Treated?
Treatment
Most low back pain can be treated without surgery. Treatment often involves:
Most patients with back pain recover without residual functional loss. Patients should contact a doctor if there is no noticeable improvement after 72 hours of self-care.
Hot/Cold
Cold and hot packs for some, may help reduce pain and inflammation and
allow greater mobility. Apply a cold compress to the tender spot several
times a day for up to 20 minutes.
After a few days of cold treatment, apply heat for brief periods to relax
muscles and increase blood flow. Warm baths may also help. Patients should avoid
sleeping on a heating pad, which can cause burns and lead to additional tissue
damage.
Rest
Bed rest? Experts suggest only 1 to 2 days at most. You should resume activities
as soon as possible.
Exercise
Exercise may be an
effective way to speed recovery from low back pain and help strengthen muscles.
This is particularly important for persons with skeletal irregularities.
Physical therapists
can provide a list of gentle exercises that help keep muscles moving and speed
the recovery process.
These may include:
●stretching
exercises
●swimming
●walking
●tai
chi or other movement therapy
●yoga
Mild discomfort felt at the start of these exercises should disappear as muscles
become stronger. But if pain is more than mild and lasts more than 15 min.
during exercise, patients should stop and contact a doctor.
Part 7 of 10 - What Medications Are Used To Treat Lower Back Pain?
Medications are often used to treat acute and chronic low back pain.
Effective pain relief may involve a combination of prescription drugs and over-the-counter remedies. Patients should always check with a doctor before taking any drugs for pain relief.
OTC Drugs
Over-the-counter NSAIDs are taken orally to reduce stiffness, swelling, and inflammation and to ease mild to moderate low back pain. These drugs include:
Topicals
Topical counter-irritants applied to the skin as a cream or spray stimulate the nerve endings in the skin to provide feelings of warmth or cold and dull the sense of pain.
Many topical
analgesics can also reduce inflammation and stimulate blood flow. The
topical
salicylates also contain salicylate, the same ingredient found in oral
pain medications containing aspirin.
Anticonvulsants
Anticonvulsants may be useful in treating certain types of nerve pain and
may also be prescribed with analgesics.
Antidepressants
Some antidepressants have been shown to relieve pain (independent of their
effect on depression) and assist with sleep.
Antidepressants alter levels of brain chemicals to elevate mood and dull
pain signals. Many newer antidepressants are also being studied for their
effectiveness in pain relief.
Painkillers
Painkillers (opioids) are prescribed to treat severe acute and chronic back
pain but should be used only for a short period of time and under a doctor’s
supervision. These include:
codeine
oxycodone
hydrocodone
morphine
Part 8 of 10 - What Are Other Treatment Options For Lower Back Pain?
When back pain does not respond to more conventional approaches, patients may consider the following treatment options:
Spinal Manipulation
Spinal manipulation uses a hands-on approach in which licensed chiropractics use adjustments and a series of exercises to restore back mobility.
Acupuncture
Acupuncture involves the insertion of needles the width of a human hair along precise points throughout the body.
Biofeedback
Biofeedback is used to treat many acute pain problems. Using a special electronic machine, a patient may learn how to effect a change in response to pain.
Traction
Traction involves using weights to apply constant or intermittent force to gradually “pull” the skeletal structure into better alignment. Traction is not recommended for treating acute low back symptoms.
TENS Units
Transcutaneous electrical nerve stimulation (TENS) is given by a battery-powered device that sends mild electric pulses along nerve fibers to block pain signals to the brain. Small electrodes placed on the skin at or near the site of pain generate nerve impulses that block incoming pain signals from the peripheral nerves.
Other Treatments
Part 9 of 10 - What Are The Surgical Procedures For Lower Back Pain?
Surgical Procedures
In the most serious cases, when the condition does not respond to other therapies, surgery may relieve pain caused by back problems or serious musculoskeletal injuries. Surgical procedures can include:
Some surgical procedures may be performed in a doctor’s office under local anesthesia, while others require hospitalization.
It may be months following surgery before the patient is fully healed, and he or she may suffer permanent loss of flexibility.
Since invasive back surgery is not always successful, it should be performed only in patients with progressive neurologic disease or damage to the peripheral nerves.
Surgical Procedures For Severe Chronic Pain
Other surgical procedures to relieve severe chronic pain include:
Part 10 of 10 - Can Lower Back Pain Be Prevented?
Prevention
Recurring back pain resulting from improper body mechanics or other nontraumatic causes is often preventable. A combination of exercises that don't jolt or strain the back, maintaining correct posture, and lifting objects properly can help prevent injuries.
Many injuries are caused or aggravated by stressors such as:
Ergonomics In The Home And Workplace
Applying ergonomic principles designing furniture and tools to protect the body from injury can greatly reduce the risk of back injury and help maintain a healthy back.
To reduce the risks of musculoskeletal injury and pain, more companies are promoting better ergonomically designed:
Back Belts
The use of wide elastic belts that can be tightened to pull in lumbar and abdominal muscles to prevent low back pain is controversial.
A study of the use of back support belts worn by persons who lift or move
merchandise found no evidence that the belts reduce back injury or back pain.
Although there have been anecdotal case reports of injury reduction among
workers using back belts, many companies that have back belt programs also have
training and ergonomic awareness programs. Injury reduction may be related to a
combination of these or other factors.
