Back pain

Overview

Back pain is one of the most common reasons people seek medical help or miss work. Back pain is a leading cause of disability worldwide.

Fortunately, measures can help prevent or relieve most back pain episodes, especially for people younger than age 60. If prevention fails, simple home treatment and using the body correctly often can heal the back within a few weeks. Surgery is rarely needed to treat back pain.

Symptoms

Back pain can range from a muscle ache to a shooting, burning or stabbing feeling. Also, the pain can radiate down a leg. Bending, twisting, lifting, standing or walking can make pain worse.

When to see a doctor

Most back pain improves over time with home treatment and self-care, often within a few weeks. Contact your healthcare professional for back pain that:

  • Lasts longer than a few weeks.
  • Is severe and doesn't improve with rest.
  • Spreads down one or both legs, especially if it goes below the knee.
  • Causes weakness, numbness, or tingling in one or both legs.
  • Is paired with unexplained weight loss.

In some people, back pain can signal a serious medical problem. This is rare, but seek immediate care for back pain that:

  • Causes new bowel or bladder problems.
  • Is accompanied by a fever.
  • Follows a fall, blow to the back or other injury.

Causes

Back pain often develops without a cause that shows up in a test or an imaging study. Conditions commonly linked to back pain include:

  • Muscle or ligament strain. Repeated heavy lifting or a sudden awkward movement can strain back muscles and spinal ligaments. For people in poor physical condition, constant strain on the back can cause painful muscle spasms.
  • Bulging or ruptured disks. Disks act as cushions between the bones in the spine. The soft material inside a disk can bulge or rupture and press on a nerve. However, a bulging or ruptured disk might not cause back pain. Disk disease is often found on spine X-rays, CT scans or MRIs done for another reason.
  • Arthritis. Osteoarthritis can affect the lower back. In some cases, arthritis in the spine can lead to a narrowing of the space around the spinal cord, a condition called spinal stenosis.
  • Osteoporosis. The spine's vertebrae can develop painful breaks if the bones become porous and brittle.
  • Ankylosing spondylitis, also called axial spondyloarthritis. This inflammatory disease can cause some of the bones in the spine to fuse. This makes the spine less flexible.

Risk factors

Anyone can develop back pain, even children and teens. These factors can increase the risk of developing back pain:

  • Age. Back pain is more common with age, starting around age 30 or 40.
  • Lack of exercise. Weak, unused muscles in the back and abdomen might lead to back pain.
  • Excess weight. Excess body weight puts extra stress on the back.
  • Diseases. Some types of arthritis and cancer can contribute to back pain.
  • Improper lifting. Using the back instead of the legs can lead to back pain.
  • Psychological conditions. People prone to depression and anxiety appear to have a greater risk of back pain. Stress can cause muscle tension, which can contribute to back pain.
  • Smoking. People who smoke have increased rates of back pain. This may occur because smoking causes coughing, which can lead to herniated disks. Smoking also can decrease blood flow to the spine and increase the risk of osteoporosis.

Prevention

Improving one's physical condition and learning and practicing how to use the body might help prevent back pain.

To keep the back healthy and strong:

  • Exercise. Regular low-impact aerobic activities can increase strength and endurance in the back and allow the muscles to work better. Walking, bicycling and swimming are good choices because they don't strain or jolt the back. Talk with your healthcare team about which activities to try.
  • Build muscle strength and flexibility. Abdominal and back muscle exercises, which strengthen the body's core, help condition these muscles so that they work together to support the back.
  • Maintain a healthy weight. Being overweight strains back muscles.
  • Quit smoking. Smoking increases the risk of low back pain. The risk rises with the number of cigarettes smoked each day, so quitting can help reduce this risk.

Avoid movements that twist or strain the back. To use the body properly:

  • Stand smart. Don't slouch. Maintain a neutral pelvic position. When standing for long periods, place one foot on a low footstool to take some of the load off the lower back. Alternate feet. Good posture can reduce the stress on back muscles.
  • Sit smart. Choose a seat with good lower back support, armrests and a swivel base. Placing a pillow or rolled towel in the small of the back can maintain its typical curve. Keep knees and hips level. Change position frequently, at least every half hour.
  • Lift smart. Avoid heavy lifting, if possible. If you must lift something heavy, let your legs do the work. Keep your back straight, bend only at the knees, and don't twist. Hold the load close to your body. Find a lifting partner if the object is heavy or awkward.

Buyer beware

Because back pain is common, many products promise prevention or relief. But there's no good evidence that special shoes, shoe inserts, back supports or specially designed furniture can help.

In addition, there doesn't appear to be one type of mattress that's best for people with back pain. It's probably a matter of what feels most comfortable to each person.

Diagnosis

Your healthcare professional examines your back and assesses your ability to sit, stand, walk and lift your legs. The health professional also might ask you to rate your pain on a scale of zero to 10 and to talk about how your pain affects your daily activities.

These assessments help determine where the pain comes from and how much you can move before pain or muscle spasms force you to stop. Exams also can help rule out more-serious causes of back pain.

One or more of these tests might help pinpoint the cause of the back pain:

  • X-ray. These images show arthritis or broken bones. But the images alone won't find conditions affecting the spinal cord, muscles, nerves or disks.
  • MRI or CT scans. These scans generate images that can reveal herniated disks or problems with bones, muscles, tissue, tendons, nerves, ligaments and blood vessels.
  • Blood tests. These can help determine whether an infection or other condition might be causing pain.
  • Nerve studies. Electromyography (EMG) measures the electrical impulses produced by the nerves and how the muscles respond to them. This test can confirm pressure on the nerves caused by herniated disks or narrowing of the spinal canal, called spinal stenosis.

Treatment

Most back pain gets better within a month using home treatment, especially for people younger than age 60. However, for many, the pain lasts several months.

Pain relievers and the use of heat might be all that's needed. Bed rest isn't recommended.

Continue your activities as much as you can with back pain. Try light activity, such as walking. Stop activity that increases pain, but don't avoid activity out of fear of pain. If home treatments aren't working after several weeks, your healthcare professional might recommend stronger medicines or other therapies.

Medicines

Medicines depend on the type of back pain. They might include:

  • Pain relievers. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve), might help. Take these medicines only as directed. Overuse can cause serious side effects. If pain relievers you can buy without a prescription don't help, your healthcare professional might suggest prescription NSAIDs.
  • Muscle relaxants. If mild to moderate back pain doesn't improve with pain relievers, a muscle relaxant might help. Muscle relaxants can cause dizziness and sleepiness.
  • Topical pain relievers. These products, including creams, salves, ointments and patches, deliver pain-relieving substances through the skin.
  • Narcotics. Medicines containing opioids, such as oxycodone or hydrocodone, may be used for a short time with close medical supervision.
  • Antidepressants. Some types of antidepressants, particularly duloxetine (Cymbalta) and tricyclic antidepressants such as amitriptyline, have been shown to relieve chronic back pain.

Physical therapy

A physical therapist can teach exercises to increase flexibility, strengthen back and abdominal muscles, and improve posture. Regular use of these techniques can help keep pain from returning. Physical therapists also teach how to modify movements during an episode of back pain to avoid flaring pain symptoms while staying active.

Surgical and other procedures

Procedures used to treat back pain may include:

  • Cortisone shots, also called injections. If other measures don't relieve pain that radiates down the leg, an injection of cortisone plus a numbing medicine might help. A cortisone injection into the space around the spinal cord helps decrease inflammation around the nerve roots, but the pain relief often lasts only a month or two.
  • Radiofrequency ablation. In this procedure, a fine needle is inserted through the skin near the area causing the pain. Radio waves are passed through the needle to damage the nearby nerves. Damaging the nerves interferes with pain signals to the brain.
  • Implanted nerve stimulators. Devices implanted under the skin can deliver electrical impulses to certain nerves to block pain signals.
  • Surgery. Surgery to create more space within the spine is sometimes helpful for people who have increasing muscle weakness or back pain that goes down a leg. These problems can be related to herniated disks or other conditions that narrow the spaces where nerves pass through the spine.

Alternative medicine

A number of alternative treatments might ease back pain. Always discuss the benefits and risks with your healthcare professional before starting a new alternative therapy. Alternative treatments may include:

  • Acupuncture. A practitioner of acupuncture inserts thin sterilized needles into the skin at specific points on the body. A growing body of scientific evidence indicates that acupuncture can be helpful in treating back pain.
  • Chiropractic care. A chiropractor manipulates the spine to ease pain.
  • Massage. For back pain caused by tense or overworked muscles, massage might help.
  • Transcutaneous electrical nerve stimulation, also known as TENS. A battery-powered device placed on the skin delivers electrical impulses to the painful area. Studies have shown mixed results on whether TENS works to treat back pain.
  • Yoga. There are several types of yoga, a broad discipline that involves practicing specific postures or poses, breathing exercises, and relaxation techniques. Yoga can stretch and strengthen muscles and improve posture. People with back pain might need to adjust some poses if they make symptoms worse.

Preparing for an appointment

If your back pain persists despite home treatment, see your healthcare professional. Here's some information to help you get ready for your appointment.
