Sciatica: What Is It and How Is It Caused?

The sciatic nerve enables you to feel and control your legs. It is the longest nerve in a human’s body, running from the spinal cord to each leg. Any disturbance to this nerve results in sciatica.

However, sciatica is not a condition on its own, but rather a symptom of an underlying condition. Find out more about sciatica below and its causes.

What Causes Sciatica?

The spinal column consists of disks, vertebrae, and nerves. The disks provide cushion for the vertebra to avoid friction. When the disk slips out of place, the sciatic nerve undergoes pressure, resulting in sciatica.

Also, sciatica may occur when an infection, tumor, or injury affects the spine. A disk may also slip forward and exert pressure on the sciatic nerve. Cauda equine syndrome can also affect your spinal cord’s nerves, triggering sciatica.

Symptoms of Sciatica

If you suffer from sciatica, you may feel pain in your lower back, buttocks, and the back of your legs, which worsens when you move. You may also have weak legs and feel numbness or a burning sensation in your legs. If cauda equina syndrome is the cause of sciatica, you may be unable to control your bowel and bladder.

Predisposing Factors

Some factors may make you more susceptible to sciatica—for instance, sitting for a very long time, lifting heavy objects, or making twisting movements. In addition, as you advance in age, your body parts, such as disks, start wearing out. Smoking may also make your discs’ outer layer wear out, exposing you to sciatica.


Your doctor will try to understand your medical history. They will want to know whether you have any recent injuries. They will also want to know which activities cause the most pain.

The doctor may also conduct tests on the sciatic nerve to observe how it relays impulses. They may also subject you to imaging tests such as MRIs, X-rays, and CT scans to show any abnormalities in your spinal cord.
