Quick Scoop

Discitis is inflammation or infection of the space between the bones of the spine, called the intervertebral disc space, and it can cause severe back pain and stiffness. It is uncommon but can be serious, especially if it is not treated promptly.

What it is

Discitis usually means the disc space has become infected, most often by bacteria. The discs help cushion the spine, and because they have limited blood supply, infections there can be harder to treat.

Common symptoms

  • Severe localized back pain.
  • Pain that worsens with movement.
  • Fever, chills, fatigue, or loss of appetite when infection is present.
  • In children, refusal to walk or arching of the back can happen.

Treatment

Treatment usually includes antibiotics, and sometimes limiting movement with a brace or cast. In more serious cases, surgery may be needed if there is an abscess or another complication.

When to get help

Because discitis can lead to complications such as an epidural abscess or sepsis, new severe back pain with fever, weakness, numbness, or trouble walking should be assessed by a medical professional promptly.
