Things to know about lower back pain
Physician specialties that evaluate and treat low back pain range from generalists to subspecialists. These specialties include emergency medicine physicians, general medicine, family medicine, internal medicine, gynecology, spine surgeons (orthopaedics and neurosurgery), rheumatology, pain management, and physiatry.
Other health care providers for low back pain include physical therapists, chiropractors, massage therapists, psychologists, and acupuncturists.
What is the anatomy of the lower back?
To understand various causes of low back pain, it is important to appreciate the normal design (anatomy) of the tissues of this area of the body. Important structures of the low back that can be related to symptoms in this region include the bony lumbar spine (vertebrae, singular = vertebra), discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of the low back, internal organs of the pelvis and abdomen, and the skin covering the lumbar area.
The bony lumbar spine is designed so that vertebrae "stacked" together can provide a movable support structure while also protecting the spinal cord from injury. The spinal cord is composed of nervous tissue that extends down the spinal column from the brain. Each vertebra has a spinous process, a bony prominence behind the spinal cord, which shields the cord's nervous tissue from impact trauma. Vertebrae also have a strong bony "body" (vertebral body) in front of the spinal cord to provide a platform suitable for weight-bearing of all tissues above the buttocks. The lumbar vertebrae stack immediately atop the sacrum bone that is situated in between the buttocks. On each side, the sacrum meets the iliac bone of the pelvis to form the sacroiliac joints of the buttocks.

Nearly everyone has low back pain at some time during their life. See AnswerWhat is the anatomy of the lower back? (Continued)
The discs are pads that serve as "cushions" between the individual vertebral bodies. They help to minimize the impact of stress forces on the spinal column. Each disc is designed like a jelly donut with a central, softer component (nucleus pulposus) and a surrounding, firm outer ring (annulus fibrosus). The central portion of the disc is capable of rupturing (herniating as in a herniated disc) through the outer ring, irritating adjacent nervous tissue and sciatica as described below. Ligaments are strong fibrous soft tissues that firmly attach bones to bones. Ligaments attach each of the vertebrae to each other and surround each of the discs.
The nerves that provide sensation and stimulate the muscles of the low back as well as the lower extremities (the thighs, legs, feet, and toes) all exit the lumbar spinal column through bony portals, each of which is called a "foramen."
Many muscle groups that are responsible for flexing, extending and rotating the waist, as well as moving the lower extremities, attach to the lumbar spine through tendon insertions.
The aorta and blood vessels that transport blood to and from the lower extremities pass in front of the lumbar spine in the abdomen and pelvis. Surrounding these blood vessels are lymph nodes (lymph glands) and tissues of the involuntary nervous system that are important in maintaining bladder and bowel control.
The uterus and ovaries are important pelvic structures in front of the pelvic area of women. The prostate gland is a significant pelvic structure in men. The kidneys are on either side of the back of the lower abdomen, in front of the lumbar spine.
The skin over the lumbar area is supplied by nerves that come from nerve roots that exit from the lumbar spine.

What is the function of the lower back?
The low back, or lumbar area, serves several important functions for the human body. These functions include structural support, movement, and protection of certain body tissues.
When we stand, the lower back is functioning to support the weight of the upper body. When we bend, extend, or rotate at the waist, the lower back is involved in the movement. Therefore, injury to the structures important for weight-bearing, such as the bony spine, muscles, tendons, and ligaments, often can be detected when the body is standing erect or used in various movements.
Protecting the soft tissues of the nervous system and spinal cord as well as nearby organs of the pelvis and abdomen is a critical function of the lumbar spine and adjacent muscles of the low back.
What are common causes of lower back pain?
Common causes of low back pain (lumbar backache) include lumbar strain, nerve irritation, lumbar radiculopathy, bony encroachment, and conditions of the bone and joints. Each of these is reviewed below.
Lumbar strain (acute, chronic): A lumbar strain is a stretch injury to the ligaments, tendons, and/or muscles of the low back. The stretching incident results in microscopic tears of varying degrees in these tissues. Lumbar strain is considered one of the most common causes of low back pain. The injury can occur because of overuse, improper use, or trauma. Soft-tissue injury is commonly classified as "acute" if it has been present for days to weeks. If the strain lasts longer than three months, it is referred to as "chronic." Lumbar strain most often occurs in people in their 40s, but it can happen at any age. The condition is characterized by localized discomfort in the low back area with onset after an event that mechanically stressed the lumbar tissues. The severity of the injury ranges from mild to severe, depending on the degree of strain and resulting spasm of the muscles of the low back. The diagnosis of lumbar strain is based on the history of injury, the location of the pain, and exclusion of nervous system injury. Usually, X-ray testing is only helpful to exclude bone abnormalities.
The treatment of lumbar strain consists of resting the back (to avoid reinjury), medications to relieve pain and muscle spasm, local heat applications, massage, and eventual (after the acute episode resolves) reconditioning exercises to strengthen the low back and abdominal muscles. Initial treatment at home might include heat application, acetaminophen (Tylenol) or ibuprofen (Advil, Motrin), and avoiding reinjury and heavy lifting. Prescription medications that are sometimes used for acute low back pain include non-steroidal anti-inflammatory medications, such as sulindac (Clinoril), naproxen (Naprosyn), and ketorolac (Toradol) by injection or by mouth, muscle relaxants, such as carisoprodol (Soma), cyclobenzaprine (Flexeril), methocarbamol (Robaxin), and metaxalone (Skelaxin), as well as analgesics, such as tramadol (Ultram).
Long periods of inactivity in bed are no longer recommended, as this treatment may slow recovery. Spinal manipulation for periods of up to one month is helpful in some patients who do not have signs of nerve irritation. Future injury is avoided by using back-protection techniques during activities and support devices as needed at home or work.

Nerve irritation and lumbar radiculopathy causes lower back pain
Nerve irritation: The nerves of the lumbar spine can be irritated by mechanical pressure (impingement) by bone or other tissues, or from disease, anywhere along their
Lumbar radiculopathy: Lumbar radiculopathy is nerve irritation that is caused by damage to the discs between the vertebrae. Damage to the disc occurs because of degeneration ("wear and tear") of the outer ring of the disc, traumatic injury, or both. As a result, the central softer portion of the disc can rupture (herniate) through the outer ring of the disc and abut the spinal cord or its nerves as they exit the bony spinal column. This rupture is what causes the commonly recognized "sciatica" pain of a herniated disc that shoots from the low back and buttock down the leg. A history of localized low-back aching can precede sciatica, or it can follow a "popping" sensation and be accompanied by numbness and tingling. The back pain commonly increases with movements at the waist and can increase with coughing or sneezing. In more severe instances, sciatica can be accompanied by incontinence of the bladder and/or bowels. The sciatica of lumbar radiculopathy typically affects only one side of the body, such as the left side or right side, and not both. Lumbar radiculopathy is suspected based on the above symptoms. Increased radiating back pain when the lower extremity is lifted supports the diagnosis. Nerve testing (EMG/electromyogram and NCV/nerve conduction velocity) of the lower extremities can be used to detect nerve irritation. The actual disc herniation can be detected with imaging tests, such as CAT or MRI scanning. Treatment of lumbar radiculopathy ranges from medical management to surgery. Medical management includes patient education, medications to relieve pain and muscle spasms, cortisone injection around the spinal cord (epidural injection), physical therapy (heat, massage by a therapist, ultrasound, exercises, electrical stimulation), and rest (not strict bed rest but avoiding reinjury). With unrelenting pain, severe impairment of function, or incontinence (which can indicate spinal cord irritation), surgery may be necessary. The operation performed depends on the overall status of the spine and the age and health of the patient. Procedures include removal of the herniated disc with laminotomy (a small hole in the bone of the lumbar spine surrounding the spinal cord), laminectomy (removal of the bony wall), by needle technique (percutaneous discectomy), disc-dissolving procedures (chemonucleolysis), and others.

Bony encroachment causes lower back pain
Bony encroachment: Any condition that results in movement or growth of the vertebrae of the lumbar spine can limit the space (encroachment) for the adjacent spinal cord and nerves. Causes of bony encroachment of the spinal nerves include foraminal narrowing (narrowing of the portal through which the spinal nerve passes from the spinal column, out of the spinal canal to the body, commonly as a result of arthritis), spondylolisthesis (slippage of one vertebra relative to another), and spinal stenosis (compression of the nerve roots or spinal cord by bony spurs or other soft tissues in the spinal canal). Spinal-nerve compression in these conditions can lead to sciatica pain that radiates down the lower extremities. Spinal stenosis can cause lower-extremity pains that worsen with walking and are relieved by resting (mimicking the pains of poor circulation). Treatment of these afflictions varies, depending on their severity, and ranges from rest and exercises to epidural cortisone injections and surgical decompression by removing the bone that is compressing the nervous tissue.
Conditions of bone and joint causes lower back pain
Bone and joint conditions: Bone and joint conditions that lead to low back pain include those existing from birth (congenital), those that result from wear and tear (degenerative) or injury, and those that are due to inflammation of the joints (arthritis).
Congenital bone conditions: Congenital causes (existing from birth) of low back pain include scoliosis and spina bifida. Scoliosis is a sideways (lateral) curvature of the spine that can be caused when one lower extremity is shorter than the other (functional scoliosis) or because of an abnormal architecture of the spine (structural scoliosis). Children who are significantly affected by structural scoliosis may require treatment with bracing and/or surgery to the spine. Adults infrequently are treated surgically but often benefit from support bracing. Spina bifida is a birth defect in the bony vertebral arch over the spinal canal, often with the absence of the spinous process. This birth defect most commonly affects the lowest lumbar vertebra and the top of the sacrum. Occasionally, there are abnormal tufts of hair on the skin of the involved area. Spina bifida can be a minor bony abnormality without symptoms. However, the condition can also be accompanied by serious nervous abnormalities of the lower extremities.
Degenerative bone and joint conditions: As we age, the water and protein content of the body's cartilage changes. This change results in weaker, thinner, and more fragile cartilage. Because both the discs and the joints that stack the vertebrae (facet joints) are partly composed of cartilage, these areas are subject to wear and tear over time (degenerative changes). Degeneration of the disc is called spondylosis. Spondylosis can be noted on X-rays of the spine as a narrowing of the normal "disc space" between the vertebrae. It is the deterioration of the disc tissue that predisposes the disc to herniation and localized lumbar pain ("lumbago") in older patients. Degenerative arthritis (osteoarthritis) of the facet joints is also a cause of localized lumbar pain that can be detected with plain X-ray testing. These causes of degenerative back pain are usually treated conservatively with intermittent heat, rest, rehabilitative exercises, and medications to relieve pain, muscle spasms, and inflammation.
Injury to the bones and joints: Fractures (breakage of bone) of the lumbar spine and sacrum bone most commonly affect elderly people with osteoporosis, especially those who have taken long-term cortisone medication. For these individuals, occasionally even minimal stresses on the spine (such as bending to tie shoes) can lead to bone fracture. In this setting, the vertebra can collapse (vertebral compression fracture). The fracture causes an immediate onset of severe localized pain that can radiate around the waist in a band-like fashion and is made intensely worse with body motions. This pain generally does not radiate down the lower extremities. Vertebral fractures in younger patients occur only after severe trauma, such as from motor-vehicle accidents or a convulsive seizure.
In both younger and older patients, vertebral fractures take weeks to heal with rest and pain relievers. Compression fractures of vertebrae associated with osteoporosis can also be treated with a procedure called vertebroplasty or kyphoplasty, which can help to reduce pain. In this procedure, a balloon is inflated in the compressed vertebra, often returning some of its lost height. Subsequently, a "cement" (methylmethacrylate) is injected into the balloon and remains to retain the structure and height of the body of the vertebra. Pain is relieved as the height of the collapsed vertebra is restored.
Arthritis: The spondyloarthropathies are inflammatory types of arthritis that can affect the lower back and sacroiliac joints. Examples of spondyloarthropathies include reactive arthritis (Reiter's disease), ankylosing spondylitis, psoriatic arthritis, and the arthritis of inflammatory bowel disease. Each of these diseases can lead to low back pain and stiffness, which is typically worse in the morning. These conditions usually begin in the second and third decades of life. They are treated with medications directed toward decreasing inflammation. Newer biological medications have been greatly successful in both quieting the disease and stopping its progression.
What are other causes of lower back pain?
Other causes of low back pain include kidney problems, pregnancy, ovary problems, and tumors.
Kidney problems
Kidney infections, stones, and traumatic bleeding of the kidney (hematoma) are frequently associated with low back pain. Diagnosis can involve urine analysis, sound-wave tests (ultrasound), or other imaging studies of the abdomen.
Pregnancy
Pregnancy commonly leads to low back pain by mechanically stressing the lumbar spine (changing the normal lumbar curvature) and by the positioning of the baby inside of the abdomen. Additionally, the effects of the female hormone estrogen and the ligament-loosening hormone relaxin may contribute to the loosening of the ligaments and structures of the back. Pelvic-tilt exercises and stretches are often recommended for relieving this pain. Women are also recommended to maintain physical conditioning during pregnancy according to their doctors' advice. Natural labor can also cause low back pain.
Ovary problems
Ovarian cysts, uterine fibroids, and endometriosis may also cause low back pain. Precise diagnosis can require gynecologic examination and testing.
Tumors
Low back pain can be caused by tumors, either benign or malignant, that originate in the bone of the spine or pelvis and spinal cord (primary tumors) and those which originate elsewhere and spread to these areas (metastatic tumors). Symptoms range from localized pain to radiating severe pain and loss of nerve and muscle function (even incontinence of urine and stool) depending on whether or not the tumors affect the nervous tissue. Tumors of these areas are detected using imaging tests, such as plain X-rays, nuclear bone scanning, and CAT and MRI scanning.
What are uncommon causes of low back pain?
Uncommon causes of low back pain include Paget's disease of bone, bleeding or infection in the pelvis, infection of the cartilage and/or bone of the spine, aneurysm of the aorta, and shingles.
Paget's disease of bone
Paget's disease of the bone is a condition of unknown cause in which the bone formation is out of synchrony with normal bone remodeling. This condition results in abnormally weakened bone and deformity and can cause localized bone pain, though it often causes no symptoms. Paget's disease is more common in people over the age of 50. Heredity (genetic background) and certain unusual virus infections have been suggested as causes. Thickening of involved bony areas of the lumbar spine can cause the radiating lower extremity pain of sciatica.
Paget's disease can be diagnosed on plain X-rays. However, a bone biopsy is occasionally necessary to ensure the accuracy of the diagnosis. Bone scanning is helpful to determine the extent of the disease, which can involve more than one bone area. A blood test, alkaline phosphatase, is useful for diagnosis and monitoring response to therapy. Treatment options include aspirin, other anti-inflammatory medicines, pain medications, and medications that slow therate of bone turnover, such as calcitonin (Calcimar, Miacalcin), etidronate (Didronel), alendronate (Fosamax), risedronate (Actonel), and pamidronate (Aredia).
Bleeding or infection in the pelvis
Bleeding in the pelvis is rare without significant trauma and is usually seen in patients who are taking blood-thinning medications, such as warfarin (Coumadin). In these patients, rapid-onset sciatica pain can be a sign of bleeding in the back of the pelvis and abdomen that is compressing the spinal nerves as they exit to the lower extremities. Infection of the pelvis is infrequent but can be a complication of conditions such as diverticulosis, Crohn's disease, ulcerative colitis, pelvic inflammatory disease with infection of the Fallopian tubes or uterus, and even appendicitis. Pelvic infection is a serious complication of these conditions and is often associated with fever, lowering of blood pressure, and a life-threatening state.
What are other uncommon causes of low back pain?
Infection of the cartilage and/or bone of the spine
Infection of the discs (septic discitis) and bone (osteomyelitis) is extremely rare. These conditions lead to localized pain associated with fever. The bacteria found when these tissues are tested with laboratory cultures include Staphylococcus aureus and Mycobacterium tuberculosis (TB bacteria). TB infection in the spine is called Pott's disease. These are each very serious conditions requiring long courses of antibiotics. The sacroiliac joints rarely become infected with bacteria. Brucellosis is a bacterial infection that can involve the sacroiliac joints and is usually transmitted in raw goat's milk.
Aneurysm of the aorta
In the elderly, atherosclerosis can cause the weakening of the wall of the large arterial blood vessel (aorta) in the abdomen. This weakening can lead to a bulging (aneurysm) of the aorta wall. While most aneurysms cause no symptoms, some cause pulsating low back pain. Aneurysms of a certain size, especially when enlarging over time, can require surgical repair with a grafting procedure to repair the abnormal portion of the artery.
Shingles
Shingles (herpes zoster) is an acute infection of the nerves that supply sensation to the skin, generally at one or several spinal levels and on one side of the body (right or left). Patients with shingles usually have had chickenpox earlier in life. The herpes virus that causes chickenpox is believed to exist in a dormant state within the spinal nerve roots long after the chickenpox resolves. In people with shingles, this virus reactivates to cause infection along the sensory nerve, leading to nerve pain and usually an outbreak of shingles (tiny blisters on the same side of the body and at the same nerve level). The back pain in patients with shingles of the lumbar area can precede the skin rash by days. Successive crops of tiny blisters can appear for several days and clear with crusty inflammation in one to two weeks. Patients occasionally are left with more chronic nerve pain (postherpetic neuralgia). Treatment can involve symptomatic relief with lotions, such as calamine, or medications, such as acyclovir (Zovirax), for the infection and pregabalin (Lyrica) or lidocaine (Lidoderm) patches for the pain.
What are risk factors for lower back pain?
Risk factors for low back pain include athletic activity, heavy lifting, throwing, moving luggage, traumatic injury, kidney infection, pregnancy, osteoporosis, and aging.
What are other symptoms and signs sometimes associated with lower back pain?
Low back pain can cause a wide variety of symptoms and signs depending on the precise cause of the back pain as reviewed above. Symptoms that can be associated with low back pain include numbness and/or tingling of the lower extremities, incontinence of urine or stool, inability to walk without worsening pain, lower extremity weakness, atrophy (decreased in size) of the lower extremity muscles, rash, fever, chills, weight loss, abdominal pains, burning on urination, dizziness, joint pain, and fatigue.
How do health care professionals diagnose lower back pain?
The diagnosis of low back pain involves a review of the history of the illness and underlying medical conditions as well as a physical examination. A complete story of the back pain must be reviewed including injury history, aggravating and alleviating conditions, associated pain symptoms (fever, numbness, tingling, incontinence, etc.), as well as the duration and progression of symptoms. Aside from routine abdomen and extremity evaluations, rectal and pelvic examinations may eventually be required as well. Further tests for diagnosis of low back pain can be required including blood and urine tests, plain film X-ray tests, CAT scanning, MRI scanning, bone scanning, and tests of the nerves such as electromyograms (EMG) and nerve conduction velocities (NCV).
What are treatment options for lower back pain?
So, how is low back pain treated? As described above, the treatment very much depends on the precise cause of the back pain. Moreover, each patient must be individually evaluated and managed in the context of the underlying background health status and activity level.
As has been highlighted by research presented at the national meeting of the American College of Rheumatology, a very important aspect of the individual evaluation is the patient's understanding and perception of their particular situation. British researchers found that those who believed that their symptoms had serious consequences on their lives and that they had, or treatments had, little control over their symptoms were more likely to have a poor outcome. This research points out to physicians the importance of addressing the concerns and perceptions that patients have about their condition during the initial evaluations.
Finally, it should be noted that the conditions listed above are intended for general review. There are many other possible causes of back pain, including upper back pain, that have not been discussed.
Are there home remedies or other treatments for lower back pain?
Self-care remedies for pain relief include cold packs and heat applications, topical analgesic balms, avoiding reinjury, eliminating heavy lifting, and taking over-the-counter pain relievers such as acetaminophen (Tylenol), naproxen (Aleve), and ibuprofen (Advil, Motrin).
What is the prognosis for lower back pain?
The outlook for low back pain depends on its precise cause. For example, acute strain injuries generally heal entirely with minimal treatment. On the other hand, bony abnormalities that are irritating the spinal cord can require significant surgical repair and the outlook depends on the surgical result. Long-term optimal results often involve exercise rehabilitation programs that can involve physical therapists.
Is it possible to prevent lower back pain?
Avoiding injury to the low back is a method of preventing low back pain. Additionally, conditioning exercise programs designed to strengthen the lumbar area and adjacent tissues can help to minimize the risk of injury to the low back. Specific programs to relieve and prevent back pain can be designed with the help of physical therapists and other treating health care professionals.
Which healthcare specialties treat lower back pain?
Physician specialties that evaluate and treat low back pain range from generalists to subspecialists. These specialties include emergency medicine physicians, general medicine, family medicine, internal medicine, gynecology, spine surgeons (orthopaedics and neurosurgery), rheumatology, pain management, and physiatry.
Other health care providers for low back pain include physical therapists, chiropractors, massage therapists, psychologists, and acupuncturists.
