Back Pain

Explore the available health information, treatment context, and integrative evidence for Back Pain.

Background
  • Back and neck pain are the most common chronic pain conditions. Back and neck pain can arise from soft tissues, bony parts of the back and neck, and joints holding the spine in alignment. It can arise directly or indirectly from the discs in the back or neck, and it can occur when nerves and nervous tissue, normally protected by the bones of the spine, are compressed by those bones.
  • Back pain can range from a dull, constant ache to a sudden, sharp pain that leaves the individual suffering and/or incapacitated. Back pain can be acute (immediate) or chronic (long-term). Acute back pain usually gets better on its own without treatment. However, chronic back pain may require medication and/or surgery.
  • The back is an intricate structure of bones, ligaments, muscles, nerves, and tendons. The spine, or backbone, is made up of 33 bony segments called vertebrae. The vertebrae are arranged in a long vertical column and held together by ligaments that are attached to muscles by tendons. Between each vertebra lies a gel-like cushion called an intervertebral disc, consisting of a semi-fluid matter that is surrounded by a capsule of elastic fibers.
  • The spinal cord is an extension of the brain that runs through a long, hollow canal in the column of the vertebrae. The meninges (membranes that surround the brain and spinal cord), cerebrospinal fluid (fluid that circulates around the brain and spinal cord), fat, and a network of veins and arteries nourish and protect the spinal cord.
  • Thirty-one pairs of nerve roots emerge from the spinal cord through spaces in each vertebra. The spinal cord and peripheral (outside the brain and spinal column) nerves perform essential sensory and motor activities of the body. The peripheral nervous system conveys sensory information from the body to the brain and conveys motor signals from the brain to the body.
  • Back problems are the most frequent cause of activity limitations in working-age adults. The American Academy of Family Physicians estimates that about 85% of Americans experience back pain by age 50. More than 26 million Americans between the ages of 20-64 experience frequent back pain. Two-thirds of American adults will have back pain during their lifetime. Back pain is the leading cause of disability in Americans under 45 years old.
  • Each year 13 million people go to the doctor for chronic back pain. It is estimated that the condition leaves 2.4 million Americans chronically disabled and another 2.4 million temporarily disabled. Back pain is the second most common reason why individuals in the United States seek medical care from their primary care physicians.
Risk Factors and Causes
  • Age: The first attack of low back pain typically occurs between the ages of 30-40. Back pain becomes more common with age. Aging produces wear and tear on the spine that may result in conditions (such as disc degeneration or spinal stenosis) that produce neck and back pain. Having a previous back injury puts the individual at risk for another injury and increased pain.
  • Diet: A diet high in calories and fat, especially trans-fats found in fried foods, combined with an inactive lifestyle, can lead to obesity. Obesity has been found to be a major risk factor in the development of back pain due to increased stress on the back.
  • Heredity: Some causes of back pain, including disc disease, may be genetic or passed from one generation to the next through genes. More research is being performed in the area of back pain and heredity.
  • Race: Race can be a factor in back problems. African American women, for example, are two to three times more likely than white women to develop spondylolisthesis, a condition in which a vertebra of the lower spine (lumbar spine) slips out of place.
  • Occupation: Physically demanding occupations, such as construction work and healthcare, which require repetitive bending and lifting, have a high incidence of back injury. Jobs that require long hours of standing without a break (such as hairdressing and fast food service) or sitting in a chair that does not support the back well (computer keyboard operation or writing) also put a person at risk for neck and lower back injury.
  • Lifestyle: Back pain is more common among people who are not physically fit. Weak back and abdominal muscles may not properly support the spine. Clinical studies report that low-impact aerobic exercise is good for the discs that cushion the vertebrae.
  • Although smoking tobacco may not directly cause back pain, it increases the risk of developing low back pain and low back pain with sciatica. Sciatica is back pain that radiates to the hip and/or leg due to pressure on a nerve. Smoking has been reported to negatively affect bone mineral density, lumbar disk disease, the rate of hip fractures, and the rate and extent of bone and wound healing.
  • Poor posture, such as slouching in a chair, driving hunched over, standing incorrectly, and using poor body mechanics when lifting and carrying heavy loads, are risk factors. Sleeping on a soft or sagging mattress also can lead to back pain.
  • Sports that involve twisting the back, such as golf and basketball, can result in back injury and they also worsen existing lower back pain.
  • Movement problems: A movement or mechanical problem is a problem with the way the spine moves or the way an individual feels when they move the spine in certain ways. Perhaps the most common mechanical cause of back pain is intervertebral disc degeneration. In this condition, the discs located between the vertebrae of the spine break down with age. As the vertebrae deteriorate, they lose their cushioning ability. This problem can lead to pain if the back is stressed. Other mechanical causes of back pain include spasms, muscle tension, and ruptured or herniated discs.
  • Injuries: Spinal injuries, such as sprains and fractures, can cause either acute (short-lived) or chronic (long-term) pain. Sprains or tears in the ligaments that support the spine can occur from twisting or lifting improperly. Fractured vertebrae are often the result of osteoporosis, a condition that causes weak, porous bones. Less commonly, back pain may be caused by more severe injuries that result from accidents and falls.
  • Whiplash is a non-medical term used to describe neck pain following an injury to the soft tissues of the neck, specifically ligaments, tendons, and muscles. Whiplash is caused by an accidental motion or force applied to the neck that results in movement beyond the neck's normal range of motion. Whiplash occurs in motor vehicle accidents, sporting activities, accidental falls, and assault.
  • Conditions and diseases: Many diseases can cause or contribute to back pain. These include various forms of arthritis, such as herniated disk (occurs when disk material presses on a nerve), osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, and cancers from elsewhere in the body that may spread to the spine. Scoliosis, which causes curvature of the spine, does not usually cause pain until mid-life. Spinal stenosis, or a narrowing of the spinal column that puts pressure on the spinal cord and nerves, also contributes to back pain. While osteoporosis itself is not painful, it can lead to painful fractures of the vertebrae. Other causes of back pain include pregnancy, kidney stones or infections, endometriosis (the buildup of uterine tissue in places outside the uterus), and fibromyalgia (which causes fatigue and widespread muscle pain).
  • Infections and tumors: Although they are not common causes of back pain, infections can cause pain when they involve the vertebrae. Osteomyelitis is an infection (typically caused by bacteria) of bone and bone marrow in which the resulting inflammation can lead to a reduction of blood supply to the bone. Discitis is when the infection involves the discs that cushion the vertebrae. Tumors are relatively rare causes of back pain. Occasionally, tumors begin in the back, but more often they appear in the back as a result of cancer that has spread from elsewhere in the body.
  • Emotional stress: Although the causes of back pain are usually physical, emotional stress may also play an important role in back pain and how severe and long it lasts. For example, stress may cause back muscles to become tense and painful.
Signs and Symptoms
  • Pain: Pain can be constant or intermittent (off and on). Intensity can vary from a dull ache to searing agony. The onset may be sudden or acute (short-term), with or without apparent reason, or gradual and chronic (long-term).
  • Most back pain resolves in a few days or weeks with or without treatment. However, some individuals have chronic pain that lasts months or years.
  • Severe pain lasting more than a few days without improvement may require medical attention. Individuals having difficulty passing urine; numbness in the back or genital area; numbness, pins and needles, or weakness in the legs; shooting pain down the leg; or unsteadiness when standing should see a doctor immediately.
  • Pain is often described as aching, tight, stiff, sore, burning, throbbing, or pulling. The pain may worsen while bending, sitting, walking, or standing too long in one position. It may also be more prevalent at different times of the day, such as when a person wakes up in the morning.
  • Pinched nerves produce numbness or tingling, warm or cold sensations, and burning or stabbing pain that begin in the back and radiate down the leg or the arm. Activities such as coughing, sneezing, or walking may increase pressure on the pinched nerve and aggravate the pain.
  • Compressed nerves may cause numbness and weakness in the muscle associated with the nerve. The muscle may atrophy (waste away) if the compression is not relieved.
Diagnosis
  • Examination: Diagnosing the underlying cause of neck and back pain can be difficult. A medical history that includes age, weight, current and past medical problems, medications, and height is taken. Also, a complete physical examination, which may include a neurological exam, is performed.
  • X-ray: X-rays show the alignment of the spine and may reveal degenerative joint diseases, fractures, or tumors.
  • Magnetic resonance imaging: Magnetic resonance imaging (MRI) scans provide clear images of disc deterioration, pathologies of the spinal cord, spinal stenosis, herniated discs, spinal tumors, and abnormalities in nerves and ligaments. MRIs are conducted in a small, confined areas and some individuals may find this uncomfortable. Some individuals may have to be sedated using a mild sedative such as alprazolam (Xanax®) or lorazepam (Ativan®). If the individual is sedated, transportation should be organized with a family member or friend to take and return home the individual, due to drowsiness and decreased coordination.
  • Computerized tomography: Computerized tomography (CT) scan is an X-ray that uses computer technology and can be enhanced with the injection of a contrast dye. CT scans are used to show abnormalities in bones and soft tissue. CT scans can be used for individuals who are unable to tolerate MRIs.
  • Myelography: Myelography is used to examine the spinal canal and cord. Contrast dye is injected into the cerebrospinal fluid in the spine. This allows the doctor to outline the spinal cord and nerve roots, and abnormal disc conditions or bone spurs can then be visualized using an X-ray or CT scan.
  • Electromyogram: Electromyogram, or EMG, is the use of tiny electrodes inserted into muscle tissue to test for abnormal electrical signals. Abnormal electrical signals may indicate that a nerve root is pinched or irritated at the spine. An anesthetic, such as lidocaine or Xylocaine®, is used to reduce the pain of electrode insertion into the skin.
  • Spinal tap: Spinal tap involves drawing a sample of cerebrospinal fluid and analyzing it for elevated pressure, infection, bleeding, or tumor. Spinal tap may be painful and may require sedation.
  • Radioactive bone scan: Radioactive bone scans locate problems (such as a fracture or osteoporosis) in the vertebrae. A chemical called a radioactive tracer is injected into the patient and after several hours, a gamma camera picture will reveal bone undergoing rapid changes where large amounts of tracer accumulate.
Complications
  • Complications of back pain include: limited mobility, such as trouble walking up stairs, standing, or sitting; pain; lost work time; surgery; and disability.
Treatment
  • In many cases, it is not necessary to see a doctor for back pain because pain usually goes away without treatment. However, an individual should see a doctor if they experience numbness or tingling, severe pain, or pain that does not improve with medication and rest. Also, individuals should see a doctor if they have pain after a fall or an injury. It is also important to see a doctor if pain occurs along with any of the following problems: trouble urinating; weakness, pain, or numbness in the legs; fever; or unintentional weight loss. Such symptoms could signal a serious medical condition that requires treatment.
  • Applying ice as soon as possible during the 48 hours after straining a muscle can reduce pain. Ice slows inflammation and swelling, numbs soft tissue, and slows nerve impulses in the injured area. After spasms and acute pain subside, heat can be applied to loosen tight muscles. Over-the-counter (OTC) pain-relieving medications, such as acetaminophen (Tylenol®), ibuprofen (Advil®), or naproxen (Aleve®), may be used for short-term (less than two weeks). Two or three days of bed rest followed by a gradual return to normal activity is sometimes recommended.
  • Physical therapy and exercise: A physical therapist may apply a variety of treatments (such as heat, ice, ultrasound, electrical stimulation, and muscle release techniques) to the back muscles and soft tissues to reduce pain. As pain improves, the physical therapist can teach the individual specific exercises to increase flexibility, strengthen the back and abdominal muscles, and improve posture. Regular use of these techniques may help prevent pain from coming back. Exercise can correct current back problems, help prevent new ones, and relieve back pain, particularly after an injury. Exercise also strengthens bones and reduces the risk of falls and injuries.
  • Prescription medications: A doctor may prescribe non-steroidal anti-inflammatory drugs (such as flurbiprofen or Ansaid® and celexocib or Celebrex®), muscle relaxants (such as cyclobenzaprine or Flexeril®), and narcotic pain relievers (such as hydrocodone or Lortab®). A skin patch containing an opioid called transdermal fentanyl (Duragesic®) may relieve chronic back pain more effectively than oral opioid drugs. Muscle relaxants, opiate agonists, and narcotic pain relievers may cause drowsiness. Narcotic pain relievers may also cause physical dependence and should be used with caution. Corticosteroid injections (steroids, such as dexamethasone or Decadron®) may be used if pain-relieving and anti-inflammatory medications do not offer relief. The long-term use of steroid medications can cause complications such as weakened immune systems and swelling.
  • Tricyclic antidepressants, such as amitriptyline (Elavil®) and nortriptyline (Pamelor®), may be used for numbness, burning, aching, throbbing, or stabbing pains that shoot down the limbs. Side effects of these drugs include drowsiness, dry mouth, blurred vision, and constipation.
  • Surgery: Few individuals need surgery for back pain. Surgery is usually reserved for pain caused by a herniated disk. If the individual is experiencing unrelenting pain that is unable to be relieved by medications or progressive muscle weakness caused by nerve compression, surgery may be beneficial.
  • Disc removal: There are three common types of surgeries that involve the removal of damaged or herniated discs in the spine, including laminotomy, laminectomy, and disectomy. A laminotomy is the surgical removal of part of the lamina (bony arch) above and below an affected nerve. A laminectomy consists of the surgical removal of most of the lamina of a vertebra. A laminectomy is most often performed when back pain fails to improve with more conservative medical treatments such as pain medications and physical therapy. A discectomy is the surgical removal or partial removal of a spinal disk.
  • Fusion surgery: Fusion surgery involves joining two vertebrae to eliminate painful movement. Recovery following fusion surgery generally takes longer compared to other types of spinal surgery. Patients typically stay in the hospital for three or four days, but a longer stay after more extensive surgery is not uncommon. A short stay in a rehabilitation unit after release from the hospital is often recommended for patients who have had extensive surgery, or for elderly or debilitated patients. Pain from surgery varies.
  • Intradiscal electrothermal therapy (IDET): In intradiscal electrothermal therapy (IDET), doctors insert a needle through a catheter into the damaged spinal disk. The needle is heated to a high temperature for up to 20 minutes. The heat thickens and seals the disk wall, reducing disk bulge and the related spinal nerve irritation. It is unclear whether this treatment is effective for back pain.
  • Implanted pumps: Pumps may be implanted into the spinal area to deliver a constant flow of pain-relieving medications (such as opiates like morphine). Surgically implanted spinal cord stimulators modulate the pain response so that the individual with a back condition experiences less pain. The implantation may put the individual at an increased risk for infection.
Prevention
  • Proper body mechanics: Many options exist for individuals wishing to prevent back and neck pain. Learning proper body mechanics, such as bending, lifting, and twisting, is particularly important if the individual's occupation involves repetitive bending, lifting, and twisting, as is the case with athletes and construction workers.
  • Exercise: Regular exercise helps to keep back muscles strong and flexible. Regular low-impact aerobic activities do not strain or jolt the back and neck. Low-impact aerobic exercises may also increase strength and endurance in the back and allow the muscles to function better. Walking and swimming are also recommended by health professional. Abdominal and back muscle exercises, also called core-strengthening exercises, help condition back muscles so that they function more efficiently and help protect the back from injury. Flexibility in the hips and upper legs aligns the pelvic bones to improve back comfort. A healthcare professional can help the individual choose the best exercise program.
  • Posture: Maintaining good posture, such as sitting straight in a chair and not slumping, can prevent and decrease back pain. Individuals with jobs that require long standing or sitting should take frequent breaks from standing or sitting positions to help prevent back pain.
  • Weight control: Maintaining weight within an ideal range for the individual's body size is very important. Excess weight has been directly linked with the development and worsening of back pain.
  • Diet: Eating a healthy diet is important to prevent back pain. A healthy diet, including fresh fruits and vegetables, provides the body with essential nutrients for health.
  • Quitting smoking: Smokers have diminished oxygen levels in their spinal tissues that can hinder the healing process. Clinical studies have found mixed results on whether cigarette smoking leads to back conditions, but there is evidence that smoking may increase the risk of developing sciatica or back pain that radiates to the hip and/or leg due to pressure on a nerve.
