Diagnosing back pain

Back pain is common and treatable. Your doctor may use several tests to help find the cause of your pain.

Oh, your aching back.

If it's any consolation, you're not alone. More than 80% of people experience at least one episode of low back pain in their lifetime, according to UpToDate.com.

Fortunately, most people who seek help from their doctors for back pain find relief. Most back pain requires simple, conservative treatment.

Causes of back pain

Your back is a complex structure, consisting of:

  • Vertebrae. These are the bones in your spine that are stacked one on top of another.
  • Disks, which are the shock-absorbing material between the vertebrae.
  • Spinal cord and nerves.
  • Muscles and ligaments.

Pain can be caused by problems in any of the above.

According to the American Academy of Orthopaedic Surgeons and UpToDate, some of the more common causes of back pain include the following:

Back strain or sprain. Sprains and strains can be caused by overstretching, using poor form to lift an object, or picking up something too heavy.

Wear and tear. Osteoarthritis and other so-called degenerative processes are often related to aging.

Herniated or slipped disk. As you age, the shock absorbers between your vertebrae harden and can crack or rupture. Sometimes a disk pushes out and presses on a nerve.

Osteoporosis. The loss of bone density and strength that define this disease can cause a weakened vertebra to fracture.

Less common causes for back pain include bone cancer, diseases of the spine such as spondylitis, infection and neurological problems.

Diagnosing back pain

Finding the specific cause for back pain can be difficult.

Your doctor will likely ask questions such as when the pain started, where it is located, and what aggravates or relieves it.

A physical examination might include testing reflexes and strength in your back and legs and examining your posture, stance and walk.

Your doctor also might ask you to undergo:

Blood tests to look for inflammation or infection.

X-rays to look for trauma or diseases of the spine.

Computed tomography (CT) scanning, which offers more detailed images than x-rays. The scanner is shaped like a large doughnut, which you pass through while on a table. You might be given a contrast material either by injection or to drink. The contrast material makes certain structures visible to the scanner. A CT scan can be especially helpful in finding osteoarthritis or other bone abnormalities.

Magnetic resonance imaging (MRI), which uses radio waves and magnetic fields to produce images. You lie on a table and enter a long tube, where the imaging takes place. MRIs are often used to find herniated disks or tumors.

Talk to your doctor

Call your doctor if you have pain in your back. It is most likely easily treated.
